Xanxus from Katekyo Hitman Reborn! Grew up as the extremely spoiled, bratty, and hot-tempered son of a powerful mafia don, mostly because his "dad" was too nice of a guy/too busy to raise him correctly. Had a huge case of RAAAAAGE when he found out at 16 that he was lol adopted and couldn't inherit the family. (also latent case of DADDY DOESN'T LOVE ME ENOUGH BAWWWWWWW RAAAAAAAAGE)
I just think hitting him would be really funny, though.
