Etemon

Etemon is a Puppet Digimon resembling a monkey puppet. His name comes from etekou, a Japanese word for personified monkeys.

Etemon is an Elvis impersonating rock star with a massive superiority complex. He refers to himself as the "King of Digimon" or the "Strongest Digimon Ever". His form is a humanoid literally wearing a monkey suit with sunglasses and a Monzaemon beanie strapped to his waist. It is said that his rival is Volcamon, as both of them like to sing.
