Space for next in the fight menu, look inside project for all fill in chracters in the "characters" sprite. Stat cards are in the stat sprite cards created for fun, fill in characters will not appear in the actual game, unless Super-Fun-Inc uses them as a base or something like that. Big Boomer is more of a token, not being able to be accessed in battle and is only found in the stat cards.
credit to @Super-Fun-Inc for characters and ring, i just made fill-in fighters. Nintendo for Little Mac inspiration
