Beelzebub from the game Obey me is the demon avatar of gluttony. As his title implies he has a massive appetite that seems like cannot be satisfied constantly craving for food and having zero self control around it, he always find a way to stuff himself and pig out, his eating habits caused him to gain weight noticeably but that only gave him more room to eat so he doesn't mind, he loves his family and you almost as much as he loves food and can get very angry if he doesn't get fed.
