During the ABC Reboot however only 3 bots would be in the box during the rumble, though a 9 way rumble was planned but never went ahead due to timing restraints. The reduced number of robots for the rumble was due to the fact that having so many robots in the arena at once made it pretty well impossible to film it all and make it look good for TV.
During ABC's second season rumbles had a much more important role, as they helped decide with which 4 robots out of the 12 competing would qualify. However, despite this UltraViolent qualified due to HellaChopper being unable to complete due to issues regarding the crowd's safety.
