— BattleBots: The Official Guide

BioHazard was a heavyweight robot built by Carlo Bertocchini's eponymous team, which competed in both 1999 BattleBots events and all five seasons on Comedy Central.

All iterations of BioHazard which fought in BattleBots featured the same design: a six-wheeled, box-shaped chassis equipped with a four-bar lifting arm which, when combined with its low profile and hinged skirts, found success in getting underneath an opponent, then lifting and throwing it over. Although BioHazard remained successful throughout its career, this tactic proved especially efficient early in its career as very few robots could run inverted and even fewer could self-right. With four heavyweight titles to its name, as well as one runner-up and two quarter-final finishes in that time, BioHazard is one of the most decorated robots in BattleBots history. BioHazard also won two heavyweight rumbles during its highly successful career.

BioHazard was also the first recognized BattleBots competitor to be designed entirely on a computer before a single part was purchased, and one of the shortest heavyweight robots in the sport's history at just 4" (10cm) in height. Bertocchini stated designing BioHazard's low profile frame was one of his greatest engineering accomplishments.

Having won all but one of its fights during the 1999 events, Carlo Bertocchini upgraded BioHazard again for BattleBots on Comedy Central. Its iconic lifting arm was powered by twin linear actuators run by 12V motors being operated at 24V instead, allowing for greater power output. As such, BioHazard was able to lift 220lb heavyweights quickly and efficiently and Carlo Bertocchini quoted each of the modified actuators as having a force of 1,400lbs. In Season 1.0, BioHazard advanced through its first two fights before coming unstuck in a quarter-final loss to Voltarc. It would, however, win the heavyweight rumble at the end of the competition.

In Season 2.0, BioHazard saw off M.O.E. and Suicidal Tendencies before bettering Nightmare in the last eight. A semi-final win against frenZy was followed by revenge against Vlad the Impaler as Carlo Bertocchini's team earned a second Giant Nut.

Returning as champion for Season 3.0, BioHazard comfortably dispatched of Little Sister and Incoming to reach the quarter-finals once again. Two wins by judges' decision followed against fellow veterans Tazbot and OverKill, but in a tense title-decider, BioHazard relinquished its title to Son of Whyachi.

BioHazard returned again for Season 4.0 and began with dominant wins over Stealth Terminator and Jabberwock. Rematches against Nightmare and OverKill ended in wins for BioHazard, and as it entered its third title fight in as many seasons, BioHazard defeated OverKill to regain the Giant Nut.

Entering Season 5.0 as a three-time champion, BioHazard saw off Center Punch, Greenspan, MechaVore and Aces and Eights to reach yet another final. Here, Bertocchini's team earned revenge over the robot which beat it in Season 1.0, now called Voltronic, as a fourth heavyweight title and Giant Nut was won by BioHazard.

Outside BattleBots

BioHazard also competed in US Robot Wars events and won the heavyweight title twice, both in 1996 and 1997. These accomplishments made it one of the the most successful bots in the history of combat robotics. Originally, it had two forklift-like plates on its lifting arm and no anti-wedge skirts, but it had a spring-loaded anti-intrusion device underneath its frame which prevented wedges from getting underneath. The anti-wedge skirts were added in 1997 for more protection against flipping.

Carlo Bertocchini and BioHazard continued to appear in combat events until the November 2005 ComBots Cup, event where it suffered two extremely destructive losses at the hands of more powerful horizontal spinners. Despite a strong performance against Megabyte in the preliminary round, where it deflected and at one point lifted the latter against the corner, it was eventually immobilized while also suffering significant damage to its lifter and skirts. Against Brutality in the loser's bracket, BioHazard suffered even more severe damage to its chassis, leading to its retirement from robot combat.

BioHazard remains in the possession of Bertocchini to this day, stored in his garage with his silverware from competing, though the robot resides in his basement still bearing heavy damage from its final event. Bertocchini himself remained partially involved in the sport beyond its Comedy Central years, most recently providing Lisa Winter with the kit chassis during the construction of Plan X. In honor of its pedigree in the sport, BioHazard cemented its place in The Combat Robot Hall of Fame in 2003.

Robot History

Long Beach 1999
BioHazard vs. Kill-O-Amp After receiving a bye in round one, BioHazard went up against Kill-O-Amp. The fight began with Kill-O-Amp charging straight forward at BioHazard, but Kill-O-Amp would harmlessly bounce off the front skirts of BioHazard. Minutes would go by with Kill-O-Amp repeatedly failing to gain any kind of advantage. BioHazard won by knockout and advanced to the next round.
BioHazard vs. Monster Monster drives over BioHazard. BioHazard's next fight came against Monster in a rematch from the 1997 US Robot Wars event. Carlo Bertocchini's robot proved consistently lower than its opponent as Monster was reduced to driving over BioHazard. Both robots survived the distance and BioHazard won by crowd vote.
BioHazard vs. Tazbot BioHazard flips Tazbot onto its back. In its next fight, BioHazard faced Donald Hutson and Tazbot. Bertocchini's opponent moved slowly hoping to test their new tail and anti-wedge devices which circled its perimeter. The only chance that Tazbot had to get under BioHazard was when it drove itself over the killsaws and a skirt was lifted for one second, but Tazbot missed this chance. BioHazard soon pushed Tazbot against the arena wall where it got underneath Tazbot and flipped it onto the killsaws. During the remaining four minutes, Tazbot tried to self-right with its arm before it was counted out. BioHazard won by KO at 2:34.
BioHazard vs. KillerHurtz BioHazard moved on and now faced John Reid and KillerHurtz. BioHazard picked up another win by knockout and advanced to the finals, stretching its unbeaten streak to four fights.
BioHazard vs. KillerHurtz BioHazard lifts KillerHurtz onto its side. BioHazard to the Gigabot finals, where it immediately got a rematch against KillerHurtz. The Team Hurtz robot performed better this time around, but was lifted by BioHazard, who won the crowd vote after both bots survived the full duration of the match.
Gigabot Royal Rumble BioHazard lifts Malicious Mischief onto Juggernaut. BioHazard and The Mauler being separated after the rumble ended. BioHazard also participated in the Gigabot Royal Rumble at the end of the tournament. In the beginning, BioHazard pushed Juggernaut against the spikestrip and tried to flip it, but missed and backed away. BioHazard headed toward the left side of Malicious Mischief and flipped it against Juggernaut. BioHazard then went after Rhino and flipped it onto its back. BioHazard then got underneath the right side of The Mauler and nearly flipped it onto its back. After BioHazard pushed Punjar against the spikestrip, the rumble was halted due to Juggernaut catching fire. When the rumble resumed, BioHazard started pushing S.L.A.M., Punjar, and Kill-O-Amp. BioHazard got underneath The Mauler again and started lifting it, but BioHazard got its lifting arm stuck under the front of The Mauler and couldn't free itself. As this was happening, Tazbot got its lifting arm underneath The Mauler and tried to free it from BioHazard. For the rest of the rumble, BioHazard pushed The Mauler against the arena wall and dragged it around the BattleBox. In the end, Razer was declared the winner of the Gigabot rumble and BioHazard lost overall.
Las Vegas 1999
BioHazard vs. frenZy BioHazard lifts frenZy against the wall. BioHazard returned to BattleBots later that year as the reigning champion. Like last time, BioHazard was given a first round bye and faced frenZy in the Round of 16. BioHazard dominated the fight, flipping frenZy numerous times until BioHazard managed to tip frenZy onto its back, and for some reason, frenZy was unable to self-right, so BioHazard won the fight by knockout.
BioHazard vs. Vlad the Impaler Vlad the Impaler flips BioHazard over the killsaws. BioHazard advanced to the quarter-finals where it fought Vlad the Impaler. BioHazard immediately drove across the BattleBox to meet Vlad, but its front skirts got lifted up, allowing Vlad the Impaler to get underneath BioHazard and push it into the arena spikes. This upended BioHazard against the arena Lexan and it landed directly on top of Vlad the Impaler's rear. Vlad then charged across the BattleBox with BioHazard still mounted on its back. It got BioHazard caught on a set of killsaws, damaging a skirt before reversing and ramming BioHazard onto another set of killsaws. The resulting impact combined with BioHazard's arm being raised at that moment flipped BioHazard. BioHazard tried to self-right, but the lifting arm jammed against something when it tried to move back into its socket, preventing it from retracting fully and therefore hindering BioHazard's attempts at righting itself. BioHazard was counted out and eliminated from the tournament.
Gigabot Rumble BioHazard flips Blendo. BioHazard later returned for the Gigabot Rumble at the end of the competition, lifting several robots into the air such as Tazbot and Mortis, and even flipping Blendo completely over. By the end of the fight, its arm was stuck open, but the remaining robots were luckily clumped together as the time ran out. BioHazard ended up winning the rumble on a judges' decision.
Season 1.0
BioHazard vs. Mjollnir BioHazard pushes Mjollnir to the killsaws, which causes Mjollnir to lose one of its wheels. BioHazard returned for the first televised BattleBots competition on Comedy Central and in the first round, faced Mjollnir. Nothing very much exciting happened in the battle as BioHazard had a hard time lifting Mjollnir's awkward frame with its arm. BioHazard and Mjollnir were hit hard by the killsaws, which caused sparks to fly from BioHazard and Mjollnir's tires to come off. In the end, BioHazard won on a unanimous 9-0 judges' decision.
BioHazard vs. Blendo BioHazard lifts Blendo. This win put BioHazard to the Round of 16, where it faced the highly destructive Blendo. In the match, BioHazard went straight at Blendo and Blendo managed to rip off the lifting front of BioHazard. However, this impact caused Blendo's engine to stall and BioHazard flipped Blendo up and over for the KO.
BioHazard vs. Voltarc Voltarc drags BioHazard into the killsaws. Now in the quarter-finals, BioHazard took on Stephen Felk and Voltarc. The match began with both bots moving around each other, and BioHazard almost lifted Voltarc twice. However, the tide turned when Voltarc was able to get underneath BioHazard and lift it up with its articulated arm. BioHazard was completely at Voltarc's mercy for the rest of the match and visited every killsaw in the BattleBox which caused many sparks to fly from BioHazard's armor. Since the rule in Season 1.0 only directly prohibited pinning the opponent against the wall, Voltarc was able to completely control the fight. Voltarc won on a unanimous 9-0 judges' decision and BioHazard was eliminated from the tournament.
Heavyweight Royal Rumble BioHazard again entered the Heavyweight Royal Rumble at the end of the main competition. BioHazard started lifting the back of Voltarc and attempted to flip Vlad the Impaler, but failed to overturn it. BioHazard then went after Punjar and its arm was stuck underneath the wedge-shaped robot before flipping Mauler against the spikestrip. BioHazard then flipped the walker Gammatron on its side near the corner and went back for Tazbot, Voltarc, and Vlad the Impaler for the rest of the rumble. In the end, BioHazard was announced the winner of the Royal Rumble.
Season 2.0
BioHazard vs. M.O.E. BioHazard flips M.O.E. BioHazard entered BattleBots once again for Season 2.0. In its first match, it was pitted up against M.O.E. BioHazard dominated, slamming M.O.E. into the spikestrip and then pushing it over the killsaws, destroying its plastic frame. M.O.E. was flipped over and high-centered by the killsaws, and it was counted out. BioHazard won by KO at 2:22 and advanced to the Round of 16.
BioHazard vs. Suicidal Tendencies BioHazard lifts Suicidal Tendencies into the pulverizer. Next up for BioHazard was a British bot in Suicidal Tendencies. BioHazard's anti-wedge skirts prevented Suicidal Tendencies' wedge, whose two forks were bent upwards, from getting underneath it. To make matters worse for Suicidal Tendencies, BioHazard was too low for its pickaxe to reach. After nearly getting stuck under the spikestrip, BioHazard managed to get the upper hand and pin Suicidal Tendencies under the pulverizer with its lifting arm. After driving some more, BioHazard eventually pinned and flipped Suicidal Tendencies over the killsaws, taking one of its tracks off. BioHazard chased its competitor down and pinned it against the Lexan. With only a few seconds left, BioHazard managed to pin Suicidal Tendencies between the pulverizer's mounting and the Lexan wall, suspending the bot in mid-air. BioHazard did its victory dance and won on a unanimous 45-0 judges' decision.
BioHazard vs. Nightmare BioHazard takes a light hit from Nightmare. Nightmare hits BioHazard with its disk, causing a shower of sparks. Nightmare is lifted under the pulverizer by BioHazard. BioHazard then moved on to the quarter-finals once again, pitted against the feared Nightmare. Both bots came out and BioHazard drove over the killsaws accidentally while trying to get behind Nightmare. After dancing around for a few seconds, Nightmare made direct contact to the side of BioHazard with its deadly blade, causing BioHazard to be hurled across the BattleBox in a shower of sparks. This impact cut through BioHazard's anti-wedge skirt, causing part of the skirt to lift off the ground. After a few more seconds, Nightmare drove over the killsaws and its blade was forced into the ground, stopping it. BioHazard seized the opportunity and drove under Nightmare, lifted up and pinned it underneath the pulverizer, which disabled Nightmare's drive system. Nightmare was being counted out and BioHazard won by knockout after 1:36.
BioHazard vs. frenZy BioHazard under frenZy near the pulverizer. This win put BioHazard to the semi-finals, where it faced frenZy again. During this match, BioHazard experienced trouble flipping frenZy because of its round shape. Eventually, frenZy was clipped by the killsaws and flipped on its back, causing it to become immobile due to its axe ceasing to function seconds earlier. frenZy was now being counted out and BioHazard won by KO at 2:14.
BioHazard vs. Vlad the Impaler BioHazard lifts Vlad the Impaler to the pulverizer. BioHazard entered the second championship match of its BattleBots career - a rematch against Vlad the Impaler. This fight started out with both bots meeting in the middle of the box. After a few seconds, BioHazard made contact with the side of Vlad and flipped it over. Vlad self-righted and retaliated by getting underneath BioHazard and pushing it a little. BioHazard then caught the front of Vlad and tried to lift it on its side, but couldn't. Vlad got underneath BioHazard again and managed to slam Vlad into the spikes. Vlad then got underneath BioHazard a third time and rammed it into the spikes again. After a few more bumps by both bots, BioHazard finally seized the opportunity for another flip. Vlad, of course, self-righted again. Vlad then made the mistake of driving near the pulverizer, to which BioHazard responded by pinning Vlad under the pulverizer with its lifting arm. After a few hits, the pulverizer broke off its shaft. The remainder of the match involved both bots driving around each other looking for the opportunity to strike. Carlo celebrates BioHazard's Season 2.0 victory. The buzzer sounded and it was left up to a judges' decision. The judges voted 27-18 in favor of BioHazard, making it heavyweight champion for a second time.
Heavyweight Royal Rumble BioHazard also competed in the Heavyweight Rumble at the end of the tournament. In this rumble, BioHazard suffered a direct hit from KillerHurtz's axe to its lifting arm actuators, breaking them in two and damaging the motors powering it. Despite this damage, BioHazard was one of the robots still alive at the end of the tournament, but lost to Tazbot.
Season 3.0
BioHazard vs. Little Sister BioHazard flips the immobile Little Sister. BioHazard was a veteran competitor, so it was allowed to skip the qualifying rounds set in place for this season because of the large number of robots that entered. It first came up against Little Sister. The fight began with Little Sister maneuvering around BioHazard, but BioHazard responded by driving the robot into the pulverizer for a quick smack. Little Sister then took damage from the nearby killsaws. BioHazard then drove toward Little Sister, who turned around to face it and fired its flipper, almost flipping BioHazard over. Little Sister managed to get under BioHazard a second time, but its flipper was ineffective thanks to BioHazard's anti-wedge skirts. After a few moments, BioHazard was underneath Little Sister and toppled it on its back. Little Sister used its arm to self-right. BioHazard then drove Little sister into the pulverizer and then flipped Little Sister over a second time. Little Sister self-righted, but the British robot's arm appeared to be malfunctioning, as it would not come down. With one final flip, BioHazard toppled Little Sister over a third time for a knockout and moved on to the next round.
BioHazard vs. Incoming BioHazard lifts Incoming. BioHazard's next match was against Incoming. After BioHazard lifted Incoming multiple times, the time eventually ran out and BioHazard won on a 42-3 judges' decision.
BioHazard vs. Tazbot BioHazard gets locked with Tazbot. This win put BioHazard to the quarter-finals, where it faced Tazbot again. The buzzer sounded and both bots clashed in the center of the BattleBox. Both bots bumped each other around for a little bit, but then BioHazard gained the upper hand, first with a slight lift and then another, pinning Tazbot against the wall in the process. BioHazard then proceeded to maneuver Tazbot into the pulverizer for a few seconds. After escaping the pulverizer, Tazbot and BioHazard took shots from the killsaws. After a few more lifts, BioHazard finally flipped Tazbot over in the last remaining seconds of the match. BioHazard won by a 27-18 judges' decision.
BioHazard vs. OverKill BioHazard lifts OverKill. BioHazard advanced once again into the semi-finals where it faced OverKill. Ahead of the fight, OverKill's builder Christian Carlberg locked the giant knife blade so that he could try to use the wedge more. This, however, proved ineffective and the two bots drove around each other, with BioHazard getting in a couple of flips. BioHazard once again won by a 38-7 judges' decision and advanced to the title decider.
BioHazard vs. Son of Whyachi The initial hit between the 2 Heavyweights. BioHazard made it to the championship round once again, however it found itself against a more challenging opponent: BioHazard came up against Son of Whyachi. The fight had a heavy hype, as it was the first time in Season 3.0 that BioHazard had gone up against a robot built for destruction, rather than a lifter or thwacker. The fight began with BioHazard charging at Son of Whyachi, but Son of Whyachi had already got its hammers up to full speed. The resulting hit tore off BioHazard's front left skirt and sent BioHazard spinning across the BattleBox floor. BioHazard then charged at Son of Whyachi once more, but got promptly thrown across the BattleBox again. This hit caused one of Son of Whyachi's red support rods to become broken free at one end. As a result, Son of Whyachi's weapon got stuck at the Spike Strip and its body spun at full speed. This allowed BioHazard to lift Son of Whyachi into the pulverizer but once Son of Whyachi got out, BioHazard pushed Son of Whyachi into the pulverizer further, where it got hammered for 30 seconds. BioHazard then lifted Son of Whyachi into the arena Lexan, nearly flipping it. However, this hit seemingly incapacitated BioHazard, as it did not move for quite a while. During this time, Son of Whyachi got itself free from the corner of the BattleBox, spun its now-unstable hammers back up to speed, and ripped off the entire right side skirt of BioHazard. The referee then began counting out BioHazard, as it had stopped moving, but just as he reached 7, BioHazard regained control of its left side drive, and it crab-walked into the center of the BattleBox. BioHazard plowed straight into the front of Son of Whyachi and locked up its already disabled right side drive, leaving it spinning in circles. This time around, BioHazard was counted out but since BioHazard was still mobile on one side, it was changed to a judges' decision. The final scoring was 29-16 for Son of Whyachi, meaning BioHazard had lost its championship, becoming runner-up instead.
Season 4.0
BioHazard vs. Stealth Terminator BioHazard flips Stealth Terminator. BioHazard returned once again for BattleBots Season 4.0, largely unchanged from the previous season. Its first match of the season was Stealth Terminator. In the match, BioHazard attempted to flip Stealth Terminator, but both robots got caught on the killsaws. As Stealth Terminator was on the floor spinner, BioHazard finally flipped Stealth Terminator and Stealth Terminator was being counted out. BioHazard won by KO at 1:42 and advanced to the Round of 16.
BioHazard vs. Jabberwock BioHazard lifts Jabberwock against the arena wall. Now in the last sixteen, BioHazard fought Jabberwock. After BioHazard was lifting Jabberwock towards the arena wall for much of the fight, the time eventually ran out and BioHazard won on a dominant 41-4 judges' decision. However, Jabberwock's ram hit and broke a vital part to BioHazard, and so Carlo returned to his nearby shop and made a new piece for BioHazard's next battle.
BioHazard vs. Nightmare Nightmare proceeds to rip in to BioHazard. This win put BioHazard to the quarter-finals yet again, where it faced Nightmare in a rematch. At the start of the fight, the two bots met in the middle of the arena, Nightmare smashing the front of BioHazard and causing a tremendous shower of bright sparks. This attack damaged one of the actuators for the lifting arm, causing the lifting arm to malfunction for the remainder of the match. BioHazard was struck in the front again by Nightmare, sending more sparks flying. BioHazard was seemingly dazed and skidded over the killsaws, making even more sparks. Luckily for BioHazard, Nightmare's disk motor was fried, causing the disk to slow to a stop. As a compromise, Nightmare tried to push BioHazard. Because of BioHazard's low profile, Nightmare just ended up driving onto the top of BioHazard almost every time Nightmare attempted to push its low profiled foe. This continued with both bots trying to get into a position so they could shove each other around. Nightmare had started losing power to its right side drive motor, resulting in it hobbling around on one wheel, trying to avoid the killsaws. However, Nightmare managed to get its tail end on top of BioHazard, crippling BioHazard's arm and pushing BioHazard over the killsaws one last time. But it wasn't enough for Nightmare and BioHazard won on a 32-13 judges' decision.
BioHazard vs. Tazbot BioHazard lifts Tazbot. BioHazard's next opponent in the semi-finals was another rematch, this time against Donald Hutson and Tazbot. The match started with Tazbot and BioHazard immediately ramming into each other, causing BioHazard to spin 180 degrees in the air and Tazbot to be turned away from BioHazard. BioHazard was then pushed towards a pulverizer, but it escaped and Tazbot nearly got hit instead. After bumping each other a couple of times, BioHazard attempted to topple Tazbot but only succeeded in lifting the turret armed robot up. BioHazard then got under Tazbot and pushed it before letting it go and raising the lifter. BioHazard got under Tazbot again and tried to lift it, but was clipped by the killsaws and Tazbot escaped. Tazbot ran away but was clipped by the killsaws and BioHazard then pushed its opponent before firing the lifter. BioHazard got under Tazbot again and pushed around in a circle before trying to topple Tazbot. Tazbot then ran at BioHazard, driving onto and off BioHazard before fleeing with BioHazard in close pursuit. BioHazard's front skirt was hit by the killsaws before BioHazard continued to chase Tazbot around raising the lifter slightly, before turning and catching Tazbot and trying to put Tazbot on its side, only for it to fail and Tazbot's axe to get under the lifting arm, preventing the arm from going down. Tazbot removed the axe and escaped BioHazard before the low down robot got under Tazbot again. Tazbot's wheels weren't on either side of BioHazard's body, preventing it from escaping. BioHazard drove over to a pulverizer where Tazbot fell off BioHazard's back and BioHazard nearly got hit by the pulverizer. BioHazard drove at Tazbot again, getting under and attempting to topple its opponent, but Tazbot slid off and escaped. BioHazard got under Tazbot again, lifting it slightly before trying again to turn over Tazbot, only to lift it up. Tazbot escaped and headed towards the blue square. BioHazard followed and was clipped by the killsaws. Both robots started pushing each other before Tazbot ran away and BioHazard got under for a brief moment before Tazbot escaped. BioHazard ran at Tazbot but stopped. Tazbot drove onto the low down robot, which started to move again. BioHazard continued to stop and start for the last 20 odd seconds of the fight, before Tazbot got one of its small wedges stuck on BioHazard's skirt. BioHazard raised the lifter one last time before the fight ended. BioHazard won on a close 24-21 judges' decision and advanced to the heavyweight finals again.
BioHazard vs. OverKill BioHazard and OverKill face off. BioHazard pushes OverKill onto the killsaws. In its third title fight in as many seasons, BioHazard took on OverKill again. This time, Christian Carlberg opted against locking OverKill's knife blade. Both robots drove out of their squares and BioHazard drove straight into OverKill, nearly flipping it over. While OverKill was swinging its blade, BioHazard got underneath OverKill, lifted the arm and headed toward the arena wall, tipping it onto its side. OverKill landed right side up and drove back. BioHazard then took a few hits from OverKill's blade and BioHazard's skirt was lifted by the killsaws. OverKill drove itself on the killsaws and went straight at BioHazard, flipping it onto its back again. The flipped OverKill drove over the spikestrip and flipped itself back over. After it does this, OverKill tried to run away, but one of the big holes in the blade was caught on a spike on the spikestrip. BioHazard came over and started pushing on OverKill, bending the blade in the process. OverKill was now on its back and BioHazard pushed it to the middle of the BattleBox. BioHazard flipped OverKill back over again and BioHazard's lifting arm was stuck in the up position. OverKill kept hitting BioHazard with its blade and OverKill drove over BioHazard. BioHazard drove into OverKill, flipping it and started pushing OverKill. BioHazard drove straight into OverKill's wedge, but ran away before the blade could hit BioHazard. BioHazard's front skirt was flipped upwards and OverKill was caught on the killsaws again. BioHazard's arm was still seemingly stuck upwards and the front skirt fell back down on the BattleBox floor. OverKill drove onto BioHazard and BioHazard pushed OverKill onto the killsaws. Both robots tried to push the other, but neither gained an advantage before the time ran out. BioHazard won on a 27-18 judges' decision and was declared the heavyweight champion for the third time.
Season 5.0
BioHazard vs. Center Punch BioHazard lifts Center Punch. BioHazard's first fight in Season 5.0 was against Center Punch. In the match, Center Punch was driving over BioHazard and slammed itself against the spikestrip. After this, BioHazard started lifting the rear of Center Punch. However, BioHazard's lifting arm was locked on the front of Center Punch and Center Punch started pushing BioHazard toward the spikestrip. Both robots were soon separated after this and BioHazard started lifting Center Punch again before the time ran out. BioHazard won on a close 23-22 judges' decision and advanced to the Round of 16.
BioHazard vs. Greenspan BioHazard overturns Greenspan. Next up for BioHazard was Greenspan. This match was over quickly as BioHazard maneuvered over to Greenspan's side of the arena and flipped it over after having some sparks shaved off by Greenspan's spinning disk. Since Greenspan did not have a self-righting mechanism, it was counted out and BioHazard won the match by KO at 1:08.
BioHazard vs. MechaVore BioHazard lifts MechaVore over but loses its arm in the process. This win put BioHazard to the heavyweight quarter-finals, where it faced MechaVore. BioHazard started by driving at the sides of MechaVore. After getting MechaVore side-on two times, BioHazard then lifted MechaVore over completely. However, as MechaVore went over, it ripped off BioHazard's lifting arm before BioHazard finished its flip, leaving MechaVore to turn 90 degrees and gash the Lexan wall with its flywheel. MechaVore came to a rest and BioHazard balanced MechaVore on one of its top's sloped sides before MechaVore was counted out, giving BioHazard the win via KO.
BioHazard vs. Aces and Eights BioHazard gets underneath Aces and Eights. After having its lifting arm fixed, BioHazard drew Aces and Eights in the heavyweight semi-finals. Aces and Eights' driver had added two forks to the front of his machine in the hopes of getting under BioHazard's skirts. After an uneventful fight where BioHazard failed to flip Aces and Eights, BioHazard did manage to get underneath Aces and Eights multiple times during the fight. The fight went to a judges' decision, which BioHazard won 28-17.
BioHazard vs. Voltronic BioHazard lifts Voltronic against the wall. In the fight to decide the champion, BioHazard had a grudge match against Voltronic. Early on, BioHazard got under Voltronic's ground clearance and then lifted Voltronic by the side towards the wall. Voltronic escaped and BioHazard lifted Voltronic up against the wall for a second time, then reversing away and pulling Voltronic away from the wall. BioHazard then pushed Voltronic again, this time beaching Voltronic on its back with no way of self-righting. Revenge had been taken by BioHazard and it had won its third televised BattleBots championship and fourth overall.
