Biollante

Locker Room Challenger
A man who was challenged to an epic duel that would determine the destiny of the world to whoever gained the title of Lord of the Locker Room.

Episode 3
Apparently, due to the time shenanigans with Van 's time travel, the epic conflict happened in the backstage instead, and this epic conflict could be counted as an "The Final Rumble" official event which gave TFR some of it's greatest ratings ever. Sadly, this also seems to have affected the outcome of the match, having Van wins instead.

Extra Episode
Later he would go on to confront his second opponent, Aniki the fearsome, and lose again

Legends say he still haunts the locker rooms, but nobody can confirm it since no one has lived to tell the tale.
