THE LEGENDARY TRASH MAN

THE LEGENDARY TRASH MAN is a recurring character that appears multiple times if you collect enough trash.

You need to first fight his goons, then defeat him twice, including his second form, and in his last interaction, he marries you (as in the player) and joins your party.

His quirk, aside from being one of the strongest characters in the game, is his identity and theme related to trash, similar to Anitta.

The game itself describes him as:

"Your husband. Actually smells nice??? You shouldn't be able to read this."
