Mighty Moe is an amazingly old man obsessed with eternal life, which he can get by earning bonus years with good health. He discovered that almost every piece of healthy food and rep in an exercise adds twelve minutes to your life, so Moe has dedicated his life to being as healthy as possible. His long life is actually due to the fact that the underworld's outdated methods aren't able to be adjusted to take the good health habits into account. Due to this Grim admits that Moe could potentially live forever.
