Vlad the Impaler
Biohazard was the first robot to self-right in combat, against Vlad the Impaler in the 1996 tournament, however since the match had ended it made no difference to who actually won. Terminal Frenzy had attempted to right itself when it earlier came up against Biohazard, but failed to do so. The next year Vlad the Impaler fought Biohazard again, and the former used its special pneumatic lifting arm to self-right numerous times, yet it still lost the judge's decision.
