KillerB's Season 4.0 appearance.

KillerB was a heavyweight robot built by Ed Haas, Jim Gadd, and Chuck McManis and driven by Matt Kottlowski of Team KillerBotZ that competed in the final three seasons of BattleBots. It was a yellow, black and red-striped robot armed with a wedge and a piercing stinger. KillerB appeared to be a basic two-wheel drive robot, but had two omni-directional wheels underneath the robot that helped the robot move. It performed acceptably in BattleBots, reaching the televised rounds in Season 4.0, but bad luck and reliability issues prevented it from getting further than the round of 32.

KillerB also competed in the first season of Robotica and was named for the noise it made when its wheels moved.

KillerB pushes Sharkbyte against the arena wall.

Due to previously competing in Season 3.0, KillerB was allowed to skip the preliminary rounds of Season 4.0, where it eventually fought Sharkbyte. In the beginning of the match, Sharkbyte moves out of the way and KillerB slams itself into the screws. KillerB bounces back and heads toward Sharkbyte, whose weapon is spinning at full power. KillerB is able to get its wedge under Sharkbyte without getting hit by the spinning disc and drives Sharkbyte into the wall. The angle that Sharkbyte hits the wall at rips off one of the Lexan strips separating the spikes from the wall. KillerB shoves Shark Byte again and another Lexan strip is shattered. KillerB drives Sharkbyte towards the pulverizer and Sharkbyte took one hit from the pulverizer. KillerB gets underneath Sharkbyte and Sharkbyte lands on top of KillerB. KillerB slams itself against the arena wall and Sharkbyte bounces off KillerB. KillerB gets underneath SharkByte again and pushed it under the pulverizer. Sharkbyte was spinning its disc again and the fake "shark jaws" gets caught on the disc, which came off from the impact. After a few more hits from the pulverizer, Sharkbyte finally escaped and KillerB suddenly stopped moving as its speed controller had overheated. Sharkbyte then pushed KillerB under the pulverizer and KillerB was counted out. Sharkbyte won by KO at 1:52 and KillerB was eliminated from the tournament again.

KillerB was scheduled to compete in the heavyweight consolation rumble at the end of the tournament but due to technical issues, KillerB was forced to pull out.

Season 5.0

Despite reaching the round of 32 in Season 4.0, KillerB had to go through the qualifiers again in Season 5.0. However, due to lack of participants, KillerB received two byes in the final preliminary rounds. Because of this, KillerB was already back in the TV rounds, where it faced El Diablo Grande. El Diablo Grande won on a 37-8 judge's decision and KillerB was eliminated from the tournament once again.

Because it lost in the round of 64, Killer B couldn't participate the heavyweight consolation rumble at the end of the tournament. Even if it did, it wouldn't come back for the heavyweight royal rumble due to an incident with Nightmare in the heavyweight consolation rumble which resulted in all the rumbles getting cancelled.
