MetalEtemon

MetalEtemon is an Android Digimon whose name and design is derived from "Metal Etemon". It calls itself the "King of Digimon", and was once called the strongest Digimon. It went out to fight harsh battles in order to search out a mighty person, and though it was able to acquire valuable combat data, it was also considerably injured due to the constant battles. It then studied its own weaknesses from the data acquired through battling, and has now been perfectly reborn as an ultimate combat machine by converting its body to full metal. Its body surface has a full coating of the Chrome Digizoid metal used by Metal-species Digimon. Its combat abilities have been raised to their maximum, giving birth to an invincible fighter which has acquired Strong- and Dirty-style wrestling skills.[4] MetalEtemon is on good terms with WaruMonzaemon, and it is said that the WaruMonzaemon plush toy it wears on its waist is something that WaruMonzaemon sent to it.[5] The characters on its chest read "Strongest" (最強 Saikyou?).

In the Spongebob series, Etemon of the Villain League will soon become this form in a reinforcement battle in a future adventure while battling the Shell Louge Squad.
