Serial Box Killer (originally Cereal Box Killer and occasionally mistakenly referred to as Serial Bot Killer) was a lightweight robot that competed in all five televised seasons of BattleBots. It was a robot shaped and painted like a Frosted Flakes cereal box armed with a thwacking arm. The original version of the robot, however, was a simple metal box that relied on pushing power to win. It won most of its matches with good driving, and was seeded for the Season 5.0 competition.
Its name was a play on words, mixing the phrases cereal box and serial killer.
Cereal Box Killer's first and only match in Season 1.0 was against Alpha Raptor. Alpha Raptor pushes Cereal Box Killer against the spikestrip and flips it over the spikestrip. Cereal Box Killer couldn't escape and was counted out shortly after. Alpha Raptor won by KO and Cereal Box Killer was eliminated from the tournament.
Cereal Box Killer wasn't finished, however, as it participated one of two consolation rumbles at the end of the tournament. It performed really well as it won overall with Rott-Bott 2000, Sallad and Mouser Mecha-Catbot. All four robots would later participate the lightweight royal rumble right after and Mouser Mecha-Catbot won overall.
Serial Box Killer's first and only match in Season 2.0 was against Grunion. In the beginning, Serial Box Killer got stuck underneath the spikestrip and Grunion tried to free Serial Box Killer. Serial Box Killer eventually got free and got its wedge underneath Grunion. Grunion managed to escape and got caught on the killsaws. Serial Box Killer was then counted out and Grunion won by KO at 1:32. This meant that Serial Box Killer was eliminated from the tournament again.
Lightweight Consolation Rumble
Serial Box Killer wasn't finished, however, as it participated the lightweight consolation rumble at the end of the tournament. Its unknown how well it performed but it won overall with Sublime II and both advanced to the lightweight royal rumble.
Lightweight Royal Rumble
Upon receiving the referee’s signal to start, Serial Box Killer immediately rushed to the center of the arena where it collided with several robots including Scrub, Sublime 2, and Das Bot. It soon after drove itself into the spike strip, its axe becoming wedged in such a way that caused the wheels to be high centered off of the floor. It somehow eventually managed to escape, after which it was seen tangling with Mecha Tentomushi. After spending a few seconds spinning in place, it spent the remainder of the rumble attempting to push other robots, including Beta Raptor, No Tolerance III, and an immobile Toe Crusher. Eventually, it decided to attack a destroyed Scrap Daddy LW55 as it was being lifted by Das Bot, which resulted in its pickaxe being wedged underneath the jewelry-case-like robot. After a lengthy period of being pinned under Das Bot, the two bots eventually separated off camera, and Serial Box Killer roamed around the box until the time ran out. Despite managing to be among the few that remained running in the rumble, Serial Box Killer was removed from contention for the crowd vote, and lost overall to Hammerhead.
Due to its seeding, Serial Box Killer was allowed to skip the preliminary rounds of Season 3.0, where it eventually faced Junkyard Dog. Serial Box Killer won on a close 24-21 judge's decision and advanced to the round of 32, where it faced Manic Aggressive.
Serial Box Killer won on a 30-15 judge's decision and advanced to the round of 16, where it faced Gamma Raptor. Gamma Raptor flipped Serial Box Killer and pushed it underneath the pulverizer. Serial Box Killer was being counted out and Gamma Raptor won by KO. This meant that Serial Box Killer was eliminated from the tournament again.
Serial Box Killer wasn't finished, however, as it participated the lightweight royal rumble at the end of the tournament. It fell under attack by Wedge of Doom. It didn't do much after. It then thwacks Sallad. Next it tackles Gamma Raptor, who got its lower prong stuck in the Ramrods. It then got shoved into the entrance-ramp and Herr Gepoünden attacks and gets stuck in the spikes. It remained for rest of the rumble and Ziggo became the winner.
Unfortunately, Serial Box Killer was no longer seeded for this tournament and therefore, it had to go through the qualifiers again. Its first match saw it up against Claymore.
Without even touching anything, Claymore got up on edge and began to wobble around as it spun up. Serial Box Killer took the opening and rushed across the BattleBox to hit Claymore. Serial Box Killer stayed on Claymore and pushed it, not letting Claymore spin up. Eventually, Claymore's fuel line disconnected, leaving it defenseless. Serial Box Killer pushed it around the box easily, though Claymore did strike back a bit, Serial Box Killer's drive had a momentary glitch and Claymore shoved it into the spike strip, where it got stuck. However, Serial Box Killer was saved by the bell, and the match went to the judges. Serial Box Killer won on a close 24-21 judge's decision and advanced to the final preliminary round, where it faced Wham! Bam!. Serial Box Killer won on a close 23-22 split judge's decision and advanced to the TV rounds, where it faced LocoMotion. Serial Box Killer won on a 37-8 judge's decision and advanced to the round of 16, where it faced former lightweight champion, Ziggo.
Both robots went straight at each other and Ziggo hit Serial Box Killer. Ziggo was hit by Serial Box Killer and bounced back into the screws. After both robots were chasing each other, Ziggo hit the front arm of Serial Box Killer and bent it. Serial Box Killer ran into Ziggo with the arm once more and the arm was severely bent. Serial Box Killer used its bent arm frame to attack Ziggo, but the next hit from Ziggo removed Serial Box Killer's arm and the front frame, sending the bot spinning away. Serial Box Killer immediately tried to ram Ziggo again, now with much less keeping the internal components from being damaged. Serial Box Killer got hit so hard by Ziggo, it left the ground for a bit and spun around in the air at least two or three full revolutions. After landing, Serial Box Killer suddenly stopped moving and Ziggo hit it from the center of the box, knocking it all the way to the wall. Serial Box Killer came back to life, but then died again shortly after. Ziggo hit Serial Box Killer again as it was being counted out. Ziggo won by KO at 1:32 and Serial Box Killer was eliminated from the tournament.
Serial Box Killer didn't participate the lightweight royal rumble at the end of the tournament most likely due to damage in its last match against Ziggo.
Due to its seeding, Serial Box Killer was allowed to skip the preliminary rounds of Season 5.0, where it eventually faced Skid Mark. Serial Box Killer won by KO after Skid Mark's electronics self-destructed. Serial Box Killer then advanced to the round of 16, where it faced Gamma Raptor again. Gamma Raptor won by KO and Serial Box Killer was eliminated once again.
Serial Box Killer couldn't compete in the lightweight royal rumble because the rest of the rumbles were cancelled due to an accident with Nightmare during the heavyweight consolation rumble.
