Raiden - god

Raiden – Japanese god of lightning Raiden is said to love people or at least their navels, as meals. He owns a thunder beast called Raiju which he sends to earth in the form of a fireball and may go to sleep in one’s belly button if they sleep outside in a thunderstorm. If so Raiden has to wake him with a fire rrow which would be quite unpleasant to wake up to.
