SkullSatamon

SkullSatamon is an Undead Digimon whose name and design are derived from "Skull" and the mythological Satan. Pursuing strength and destruction, it fell to the Dark Area as a Fallen Angel Digimon with its appearance a ruin of what it once was. However, its wickedness was refined even more, so that its dark powers are unfathomable. Its DigiCore, concentrated with mighty powers of darkness, is the characteristic of Demon-species Digimon called the "Dark Core".

SkullSatamon was a follower of the dark lord Daemon and appeared in Tokyo just after Christmas, to find Ken. He and LadyDevimon found the Ichijouji apartment. They reported back to their master, and the next day, terrorized the city in order to lure Ken out. As MarineDevimon and LadyDevimon attacked a cruise ship and highways, SkullSatamon attacked the main city, drawing the DigiDestined to him.

Though he had to deal with MetalGreymon, MegaKabuterimon and Paildramon, he easily defeated them with his superior speed. Paildramon digivolved to Imperialdramon, but SkullSatamon attacked him immediately following his digivolution, using his Nail Bone attack to corrupt his data and leave him paralyzed. The other DigiDestined and their Digimon arrived, but were unable to do any better, and soon de-digivolved. SkullSatamon then grabbed a nearby bus full of children, and hoisted it into the air, threatening to use it to destroy both the Digimon and the children. The rest of the digimon then transferred their energy to Imperialdramon, freeing him and allowing him to mode change to Imperialdramon Fighter Mode. SkullSatamon mocked the new Digimon, only to be obliterated by it in a single blast with his Positron Laser Attack while still holding the bus in the air.

In Ultima, SkullSatamon was resurrected by Padro Lodo to serve as a Harbinger in the Organization. He commands the various Skeleton Phantoms and Demonic Imps found in Chernabog's Army of Darkness
