Mario is immortal.

Mario eats with his mouth even though he doesn't need to being Immortal.

Mario is actually immortal, a bit like that bloke in Highlander (except Mario couldn't be killed even if a fellow immortal lopped off his head. He'd just grow a new one back in seconds.)

In the far East, a hero was born. He was the offspring of a dragon and sorceress, he grew to be strong and immortal and became a legend through the ages.

Mario killed that man.
