Die Fledermaus (later renamed to Die Flendermaus Zwei) was a middleweight (later heavyweight) robot which competed in Seasons 3.0 and 5.0 of BattleBots. It was originally a two-wheeled silver weaponless box, and it won one battle before losing. It returned for Season 5.0 as a heavyweight armed with a small spinning bar, but it lost its first battle.
Die Flendermaus's first opponent ever was Agsma. Die Flendermaus won on a 26-19 judge's decision moved to the next round.
Die Flendermaus Zewi's only fight was against P.T. Brusier. Both robots went straight at each other and P.T. Bruiser's spinning bar was ripped right off from the impact. However, P.T. Bruiser still was able to control the match and win on a 26-19 judge's decision, eliminating Die Flendermaus Zewi from the tournament.
