Terry

Terry is a secondary and missable character that can be found near the end of the Nerd City's road to warn you about Heavy loser (green), and near the end of Hell's road to fight you for revenge if Anitta is dead.

He is Anitta's brother. He warns you about her being suicidal, and he will try to get revenge if she die.

If you miss his dialog in Nerd City or see his dialog while you don't have Anitta in your party, he will be mentioned as ??? for the rest of the game.

He can be unlocked as a bonus character with the "gothBF" secret code. His quirk in battle is basically being a physical attack version of Anitta, minus the randomness.

The game itself describes him as:

"Garbage goth boy. Likes gambling. Loves his sister."
