Kanji Tatsumi from Persona 4. He's always been really likable to me. He's loyal, kind, funny, and not afraid to be true to himself. Furthermore, Troy Baker steals the show as his VA.
Don't let this cute Mexican pineapple thing fool you, he is one dangerous mother fucker. Let your guard down and he will slap you in the face, suck the life out of you, melt your skin off with scaling hot water, and shoot an mexibeam of ice at you.
