Battlebots Wiki

Tantrum's Discovery Season 5 appearance.

Not to be confused with the robot that competed at Season 3.0.

Tantrum is a heavyweight robot which competed in all three seasons of the BattleBots reboot on Discovery and Science. This four-wheeled robot was armed with a spring-loaded flipping arm with 9,000 lbs of pressure. It didn't do well in its debut, only winning one match and losing two other matches.

For Season 4, Tantrum gained some new upgrades with a new body, hinged wedges at the front, and a new weapon. Replacing the titanium flipper was a unique weapon, a spinning disc that could move back and forth electrically and "punch" an opponent that got too close. This version did slightly better, going 2-2 in the main tournament, but its weapon was barely effective and hardly worked at points.

The team also competed with a similar version called Boxing Champion at the second season of King of Bots, where it had a slightly better performance.

For Season 5, Tantrum retained its puncher once again with a more downward angle to it to hit lower, it had a slightly different chassis, the addition of a wedge to the front, the fists now having flamethrowers, and a self-righter on the back. This has been the best season for Tantrum as they made it to the top 4 in the tournament with two knockouts in the season. They went 2-1 in the pre-season.

Team Seems Reasonable confirmed that they will compete on Season 6 with Tantrum along with a new robot called Blip, a flywheel flipper which was originally called MoonShot.

Discovery Season 3

Tantrum vs. Battle Royale with Cheese

Tantrum's Discovery Season 3 appearance.

Tantrum flips Battle Royale.

Tantrum takes Battle Royale to the screws.

Tantrum's first match was against Battle Royale With Cheese. Before the match, the team added an additional wedge plate on the flipper which resembled a spatula and decorative kitchen utensils on its fists. The match started off well for Tantrum as its opponent was unable to get its weapon going and was able to flip Battle Royale With Cheese almost immediately. Tantrum pushed Battle Royale With Cheese onto the screws and eventually flipped it back over. However, Tantrum remained in control as Battle Royale With Cheese was having trouble spinning up its weapon, barring one instance where Tantrum intercepted the weapon's motion. Time ran out and Tantrum won on a unanimous 3-0 judges decision.

Tantrum vs. Mecha Rampage

Mecha Rampage knocks off Tantrum's left fist

Next up for Tantrum was Mecha Rampage. When the match began, Tantrum was off to a poor start as they lost one of the cosmetic eyes. As the match progressed, Tantrum took another hit that didn't seem to do any major damage. However, Tantrum took another hit from its opponent and lost the left fist. It was also having drive issues resulting from the failed flipper mechanism that in turn pivoted such that the part of the mechanism that rotates with a chain was touching the arena floor. This lifted Tantrum's drive wheels off the arena floor where it couldn't move. Tantrum took a final hit from Mecha Rampage and was counted out, giving Mecha Rampage the win by KO.

Tantrum vs. Tombstone

Tantrum wasn't done yet, however as they volunteered to take part in an exhibition match against Tombstone. Before the match, Tantrum's builder Aren Hill, agreed to give Tombstone's builder Ray Billings a fist if it broke one off Tantrum. Tantrum also had it's left fist recreated by team Witch Doctor to look like a skeletal fist. The match got underway and Tantrum was slow to advance across the arena as it had 3 out of 6 dead motors going into the fight. By the time it reached Tombstone, Tantrum had it's left skeleton fist knocked off. Tantrum's armour was doing well to absorb the next hits but lost the other fist shortly thereafter, which was shot and embedded itself in the lighting conduit tube in the corner, narrowly missing the electrical wiring for the lights and causing a blackout. Tantrum wasn't able to move much as it had a speed controller wire knocked loose and eventually stopped moving. Tantrum desperately move with its flipper. Tantrum was counted out, giving Tombstone the win by KO and one of the two fists as a trophy.

Discovery Season 4

Tantrum vs. Jasper vs. Uppercut

Tantrum's Discovery Season 4 appearance.

Tantrum punches Jasper whilst Uppecut suffers from weapon issues

Tantrum started off its season with an untelevised rumble and fought newcomers Jasper and Uppercut. Tantrum started off strong, getting under Jasper and pushing them into the arena barrier before getting them hooked on their left side. Tantrum did its best to remove Jasper but was unsuccessful until after Uppercut came in and delivered a big hit. Tantrum finally released Jasper without causing any real damage but Jasper had lost drive and stopped moving. Tantrum then took aim at Uppercut and delivered multiple hits with its punching spinner weapon. After Uppercut had stopped moving, Tantrum continued to drive around, mostly around Uppercut as both opponents had stopped moving and were counted out, giving Tantrum the win by KO.

Tantrum vs. Gemini

Tantrum pops Fred into the air

Tantrum's next match was against veteran multibot, Gemini. Tantrum went with a more traditional front wedge to deflect blows from Gemini. As the match got underway, Tantrum had little trouble dealing with Gemini as they mostly either bounced off the wedge or went up the wedge and were thrown into the air by its spinning weapon. Tantrum continued its attacks, eventually high-centering the black Gemini robot before taking it out on the red one. However, the red Gemini got the black Gemini free from debris and Tantrum resumed the action. Tantrum managed to throw the red Gemini under the pulverizer before the black Gemini stopped moving. The match went the distance but the judges awarded a 3-0 unanimous decision to Tantrum.

Tantrum vs. Skorpios

Tantrum's next opponent was veteran Skorpios. This time, Tantrum was back to its more typical setup for the fight with its two wedgelets to accompany its spinner. Tantrum got into the match without the ability to do much as their weapon wasn't able to reach Skorpios, which resulted in them having sparks shaved off. Tantrum continued to have trouble making contact with Skorpios at all and consequently couldn't mount much of an offense at all. Still, Tantrum remained mobile for the entire fight, but the judges awarded Skorpios a unanimous 3-0 decision.

Tantrum vs. Yeti

Tantrum is smashed against the rails near the Pulverizer by Yeti

Next for Tantrum was Greg Gibson and the "Alaskan Assassin" Yeti. Tantrum got off to a bad start as it immediately had it's left fist dislodged by Yeti's and it's far right fork was bent. Nevertheless, Tantrum was doing well to absorb the attacks from Yeti and its front forks served as a shield against Yeti's drum. Tantrum continued to stay squared up to Yeti, of whom was being less aggressive than usual and careful not to drive over Tantrum's weapon. As the fight wore on, Tantrum was backed into a corner of the Battlebox and was left with it's backside exposed to Yeti's drum spinner. Tantrum's rear began taking serious abuse from Yeti, as it was continuously smashed against the rails whilst being pounded by the Pulverizer. Tantrum's bottom plate was starting to suffer damage and was hindering Tantrum's ability to drive. Tantrum was left almost motionless and was counted out, giving Yeti the win by KO.

Tantrum vs. Lucky

Tantrum is flipped upside down by Lucky

Tantrum wasn't done yet as they had an exhibition match against fellow veteran Lucky. Tantrum opted to remove its front wedgelets and just use its spinner for attacks. After a tentative start, this proved to be a poor decision as they were soon tossed by Lucky. Tantrum stayed upright but didn't really have the weapon system to take on Lucky and were tossed again. After a third toss, Tantrum attacked Lucky's side, not causing any major damage. Lucky had been having drive issues from the start of the fight but Tantrum was then tossed over, where it struggled to self-right. Eventually, Tantrum's drum mechanism gave up and caused smoke to pour out. Both robots were counted out, sending the fight to a judges decision, which ruled surprisingly for Tantrum.

Discovery Season 5

Tantrum vs. Valkyrie

Tantrum started off the 2020 season with a match against Leanne Cushing and Valkyrie.

Tantrum pins Valkyrie against the Rails

The match was off to an okay start as Tantrum pushed Valkyrie around and took only minor damage in return. Tantrum continued to control Valkyrie and managed to disable their opponent's weapon by shoving them into the arena barrier. However, these exchanges made the mechanism that allows Tantrum's weapon to move forward lock up, leaving it only to spin from its starting position. Nevertheless, Tantrum continued to control the fight until it became more of a pushing match that drained Tantrum's battery, leaving it immobile on the arena floor. Tantrum was counted out, giving Valkyrie the win by KO.

Tantrum vs. ATOM94

Tantrum gets thrown the air by ATOM94's drum.

Tantrum's next fight was against newcomer ATOM94. Tantrum removed its fists that housed its flames in favor of using the remains to self-right if needed. Tantrum started off very poorly as they were thrown onto their head right into the screws on the first hit. Luckily, Tantrum righted itself and began to take control of the fight by shoving ATOM94 into the arena barrier, nearly ending up in the screws in the process. With ATOM94's weapon spinning down, Tantrum continued to control the fight and eventually flipped them over. ATOM94 was no longer moving and was counted out, giving Tantrum the win by KO.

Tantrum vs. Gamma 9

Tantrum gets under, punches and slams Gamma 9 against the Screws

Tantrum fought Gamma 9 as the final match for their regular season in 2020. Tantrum quickly took advantage of Gamma 9's drive issues by shoving them across the arena but wasn't able to do much damage. Tantrum continued to attack, eventually flipping Gamma 9 over and ripping off their side armor. Gamma 9 righted itself so Tantrum attacked it again, causing additional damage. Finally, after over 2 minutes of attacking, Gamma 9 was suffering from Tantrum's assault and driving in circles. Gamma 9 was counted out with seconds left on the clock, Giving Tantrum the win by KO.

Tantrum vs. Fusion

Tantrum bends its spinning disc and sends Fusion flying

Tantrum managed to get into the Top 32 tournament for the first time seeded the No. 18 seed and was pitted against the No. 15 seed Whyachi Bot, Fusion. The match began with Tantrum using its speed to get under Fusion, halting Fusion's horizontal spinner against the Tantrum's front. As Fusion turned around to let its horizontal spinner spin up, Tantrum capitalized by shoving Fusion against the Rails. Backing away from Fusion's vertical spinner, Tantrum turned to its side and lands a hard driving punch to Fusion. Fusion moved away and turned 360 degrees that caused it to balance on its rear end from the angular momentum of its weapon. Tantrum went in for a huge weapon collision which sent Fusion flying into the side of the Box, causing Tantrum's weapon mount to nearly come out of its track in the exchange. With Fusion pinned against the wall, Tantrum still managed to spin up its weapon despite being bent. Tantrum backs off and chases an inverted Fusion before taking a hard shot that temporarily leaves Tantrum motionless.

Tantrum carries a burning Fusion on its head

After crab-walking temporarily, Tantrum slammed into Fusion, throwing them off-balance before taking another hard shot. Tantrum raised it's self-righter and breaks free from it's drive issues as both robots' primary weapons stop spinning with Tantrum's issue the result of a fried weapon speed controller. Tantrum charged at Fusion, whom ends up on top and bursts into flames. Tantrum carried Fusion around the Battlebox while information from both the teams and Trey Roski conflicted with one another until Fusion was extinguished and the bots were separated (this separation was cut from the TV airing). Fusion was then counted out (the countout was moved earlier from where it actually took place), giving Tantrum the win by KO and a spot into the Top 16.

Tantrum vs. Bloodsport

Tantrum then faced No.2 seed Bloodsport in the Round of 16, who had opted for the "Thicc bar" which saw them beat End Game earlier in the season. The fight started with Bloodsport attempting to find space to spin up to speed, but Tantrum chased them down. Bloodsport inevitably did spin up, but the first meaningful impact saw their own wedgelets be ripped away. Tantrum was able to tank the glancing hits Bloodsport gave, but persisted in chasing its opponent and prevent it from spinning up to full speed. It then held Bloodsport against the side of the box, getting in underneath and pinning it momentarily. Tantrum's drum was spinning, but had yet to land a punch on Bloodsport. It got underneath Bloodsport again, attempted to hold the No.2 seed against the wall, and then rammed it against the red square's screws. Bloodsport escaped and finally got up to speed, but took a hit from the pulverizer after being coerced into the corner by Tantrum. Aren Hill's machine held Bloodsport under the hammer and allowed it to deliver blows to their self-righting pole, bending it out of shape in the process. With under a minute to go, Tantrum chased Bloodsport around the box and continued to smother its attempts to spin up. A wheel then fell out of Bloodsport, allowing Tantrum to pin it under the opposite pulverizer for the remaining seconds of the fight. Tantrum won by a split decision, and moved on.

Tantrum vs. SawBlaze

Jamieson Go's SawBlaze awaited Tantrum in the next round, who made a fast start to the fight, rushing over to Tantrum's square. Tantrum drove to the center of the box and SawBlaze drove over it, taking a small hit from the drum in the process. SawBlaze's front prongs began to wheelie, but still managed to get underneath Tantrum and activate the flamethrower. Tantrum slipped away however, and took advantage of having the lower ground clearance, attacking SawBlaze head on. It then landed a punch with its drum, popping SawBlaze into the air. Struggling to get its own primary weapon into play however, Tantrum was able to outdrive SawBlaze, using its agility to pin its opponent against the screws and hold it upside-down. SawBlaze used the arm to self-right, but Tantrum again was able to slide underneath the three front prongs and render the hammer saw useless. Now halfway through the fight, Tantrum pinned SawBlaze against the wall, right in front of Jamieson Go and his team. Tantrum took the opportunity to spin its drum up to speed and deliver a punch, but this only freed SawBlaze and did not cause visible damage. Tantrum remained aggressive, overturning SawBlaze several times in the closing moments and ripping a panel away from the underside. In the closing moments however, SawBlaze managed to grip Tantrum and landed two lasting hits on its opponent. The fight went to the judges, and Tantrum won by a unanimous decision.

Tantrum vs. End Game

Next up for Tantrum was New Zealand's End Game. The fight started with Tantrum on the attack, getting around to End Game's side and ramming it into the corner. But despite trying to punch with its weapon, it failed to make the desired impact and End Game recovered. Tantrum then slid under End Game's front forks and punched more successfully, sending sparks flying on impact. It backed away for a run up, and shoved End Game into the wall again. Unfortunately for Tantrum however, smoke began to billow from the top of the robot and the weapon came to a halt. The speed controller powering the weapon and srimech had died, though Tantrum was not deterred. With a place in the final at stake, Tantrum again got underneath End Game, but retreated to the center of the box. End Game began to deliver glancing hits to Tantrum's chassis, one of which ripped a fork clean off, and then hit Tantrum with a deadly and decisive uppercut, flipping it over. Unable to self-right due to damage sustained to its speed controller earlier in the fight, Tantrum was counted out, and its run was over.
