Robot History

Season 5.0

Little Whacko's first ever match in BattleBots was against Aggravated Assault. Little Whacko won on a close 23-22 judge's decision and advanced to the final preliminary round, where it faced Shockwave. Little Whacko won on a 30-15 judge's decision and advanced to the TV rounds, where it faced Dark Steel.

In the match, Little Whacko thwacked Dark Steel several times but it could not do any damage to it. Dark Steel was able to push Little Whacko around the BattleBox and was pushing it toward the killsaws when Little Whacko thwacked Dark Steel's side and the removable link came loose. Dark Steel suddenly stopped moving and Little Whacko pushed it under the pulverizer. The immobilized Dark Steel was being counted out and Little Whacko won by KO. This win put Little Whacko to the round of 32, where it faced The Big B. The Big B won on a close 25-20 judge's decision and Little Whacko was eliminated from the tournament.

As of 2015, it is unknown if Little Whacko participated the lightweight consolation rumble at the end of the tournament. Even if it did participate, it wouldn't come back for the lightweight royal rumble due to an incident with Nightmare in the heavyweight consolation rumble which resulted in all the rumbles getting cancelled.
