Circuit Breaker was a heavyweight robot built by Team Circuit Breaker which competed in the final four seasons of the original run of BattleBots. It was a robot with a sloped circular body made from a titanium-composite air turbine (which made its armor much stronger than most other robots) and armed with a spinning mace for Season 2.0, a full-body spinning shell for Season 3.0, and an overhead spinning bar for the final two seasons of competition. It didn't do well in battle, only winning one fight, but it made a television appearance in the Season 2.0 consolation rumble.
Circuit Breaker's first and only match in Season 2.0 was against Kill-O-Amp. In the beginning of the match, Kill-O-Amp began to attack Circuit Breaker immediately and pushed it under the spikestrip. Kill-O-Amp lined up for another shot, but got stuck under the pulverizer and got hit multiple times. Kill-O-Amp stopped moving and Circuit Breaker was being counted out. Kill-O-Amp won by KO and Circuit Breaker was eliminated from the tournament.
Circuit Breaker wasn't finished however, as it participated the heavyweight consolation rumble at the end of the tournament.
Season 3.0Due to its seeding, Circuit Breaker was allowed to skip the preliminary rounds of Season 3.0, where it eventually faced FrostBite. In the match, FrostBite got underneath Circuit Breaker and pushed it onto the killsaws. FrostBite backed up and it was waiting for the killsaws to toss Circuit Breaker to the middle of the BattleBox. Circuit Breaker stopped moving and it was being counted out. FrostBite won by KO and Circuit Breaker was eliminated from the tournament again.
Because it lost in the round of 64, Circuit Breaker couldn't participate the heavyweight consolation rumble at the end of the tournament.
Circuit Breaker's first fight in Season 4.0 was against Technofool. Circuit Breaker won on a 36-9 judge's decision and advanced to the TV rounds, where it faced Greenspan. Greenspan won by KO and Circuit Breaker was eliminated from the tournament again.
Circuit Breaker was scheduled to fight Super Collider, but Team Circuit Breaker was banned from the event due to security and safety violations and so Circuit Breaker was forced to forfeit its only match. Super Collider won by default and Circuit Breaker was eliminated from the tournament once again.
