Ebidramon

Ebidramon is a Champion Level Crustacean Digimon that resembles a shrimp since Ebi is the Japanese word for shrimp.

Digimon 02
The first Ebidramon the kids encountered was under the control of one of the Digimon Emperor's Dark Rings. While the Digi-Destined were on a mission to destroy a Control Spire in the frozen part of the DigiWorld, Cody Hida and Armadillomon remained behind with Joe Kido and Gomamon while the other went ahead, to let Cody recuperate from a fall into a freezing river. While in a cave, Joe and Cody were attacked by the Emperor and a Shellmon, but Digmon took him out. The Emperor then summoned Ebidramon, and Digmon took him on, but thankfully, the other kids destroyed the Control Spire, allowing Gomamon to Digivolve to Ikkakumon, to help battle Ebidramon. Oddly, Ikkakumon apparently destroyed the Ebidramon with his Harpoon Torpedo (although Ebidramon should have been freed from the Ring with the Spire's destruction).

When Digimon started to appear in the real world, an Ebidramon was seen attacking a cargo ship on the news. The Digi-Destined headed off to various spots around the globe to round up the wild creatures, and Joe and Cody ran into an Ebidramon - possibly the one who attacked the ship, possibly not - when they were in Australia. They found Derek, an Australian DigiDestined, and his Digimon Crabmon being menaced by an Ebidramon, a Shellmon and a Gesomon, but Ikkakumon and Armadillomon scared them off with thoughts of sea-food!

The Adventurer's Battle
Ebidramon was one of the Digimon who Bio-Emerged when Mephistomon was using V-Pets to plunge Earth's electronics network into chaos. Appearing in Okinawa, he attacked a ship, and then engaged Henry Wong and Terriermon in battle. Terriermon's Bunny Blast couldn't deal any damage Ebidramon's shell, but then he Digivolved into Gargomon, and destroyed him with a Bunny Pummel.
