Scorpiomon

Scorpiomon is an Ultimate Level Crustacean Digimon. His Japanese name is Anomalocarimon which comes from Anomalocaris, a crustacean from the Cambrian period.

Digimon Adventure
Scorpiomon is a minion of MetalSeadramon, the Dark Master of the digital ocean. Shortly after the DigiDestined's first battle with the Dark Masters, they found themselves on a beach, and managed to escape an attack by Shellmon, to come across what appeared to be a snack bar. Rushing toward it, Mimi Tachikawa tripped and Joe Kido hung back to help her, while the others ran on ahead - only to be attacked by Scorpiomon! He used his Scorpion Storm attack to knock them out, and then MetalSeadramon appeared to give Scorpiomon his reward - clams! Scorpiomon LOVES clams to the point of obsession. However, as soon as MetalSeadramon realized that two DigiDestined were missing, he ordered Scorpiomon to search for them, which he did, chasing Mimi and Joe across the beach. Fortunately for them, he was not the fittest of Digimon, and couldn't keep up - but when they started interfering with his clams, he attacked them again. Zudomon and Lillymon knocked him out, and dragged him back to the snack bar, where they rescued the other DigiDestined, and left Scorpiomon in their place. When MetalSeadramon found this out, he grabbed Scorpiomon, hoisted him high into the air, and let him fall. He disappeared in the dust cloud created by his impact (whether he died or not is unknown).

Digimon 02
Four years later, when wild Digimon were appearing all over Earth, a Scorpiomon appeared in Australia, near the Great Barrier Reef. Joe and Ikkakumon were there, along with Cody Hida and Submarimon, and Ikkakumon Digivolved into Zudomon to fight the Scorpiomon, but the ferocity of their battle threatened to destroy the reef. Also present was Derek, an Australian DigiDestined boy, and his partner Crabmon, who Digivolved into Coelamon to help Zudomon and Submarimon defeat the Scorpiomon, destroy the Control Spire and send the Digimon back to the Digital World.

The Adventurer's Battle
A Scorpiomon was among the Digimon who were sent by Mephistomon to capture Minami Uehara, so she could be used to force the location of the V-Pet vaccine program out of her father. The Scorpiomon attacked the shrine that was home to Takato Matsuki’s cousin, Kai, and his grandfather, but Guilmon engaged it in battle, managing to defeat it with the help of an Aero Wing Modify Card.
