Etemon

Etemon is a Puppet Digimon whose name and design are derived from a personified monkey (猿公 Etekou?). It is an unidentified Digimon that suddenly appeared in the Digital World. It calls itself the "King of Digimon", and its fighting strength is beyond imagination. And, well, it's rumored that it pulls the strings of the mysterious Digimon "Monzaemon". It is dressed in its reinforced "Monkey Suit" (サルスーツ Saru Sūtsu?) which can endure every attack, and even today it bustles about the whole world for the sake of its unending battles.

Digimon Adventure
Etemon is the second main villain that the children encounter and come into conflict with when they arrive on the continent of Server.

History
Etemon can pinpoint their location via his Dark Network, and has a large army of Digimon working for him. The Champion forms of the children’s Digimon are not powerful enough to defeat him, and it is revealed that they need to Digivolve to their Ultimate levels to win. However, in order to do that, they have to find the crests. Through their battles with him, they each find their crest, but it turns out that more is needed to Digivolve to Ultimate.

Etemon has the character of an Elvis Presley impersonator. He is often frustrated when people fail to acknowledge his over-inflated ego. Etemon considers himself to be a great singer, and often forces his minions to praise his terrible music. His personality is later copied (without the arrogance) by SuperStarmon in Digimon Frontier.

Etemon is ultimately defeated when the children go into an upside-down pyramid to find Sora’s crest. However, they also find Datamon, a prisoner of Etemon, who kidnaps Sora and tries to use her to defeat Etemon. The children come up with a plan to infiltrate the pyramid to save her, and while carrying it out, Tai is forced to accept his courage, activating his crest. Datamon, in a last ditch effort, programs the Dark Network to absorb all Digimon in its reach, including himself and Etemon, but Etemon fuses with the Network and uses its power to attack the children. However, Greymon digivolves to MetalGreymon and uses his "Giga Blaster" to defeat Etemon. The Earthquake of MetalGreymon
