Kamemon's appearance is turtle-like Digimon and based on a PC mouse; the ball on his stomach is the track-ball, his shell is the back of the mouse, and his tail as that of a wire of a mouse. This Kamemon sounds the same to Yushima's Kamemon in Digimon Data Squad.
Kamemon is a Digimon who's constantly underfoot in Rodney's house, kindly serving drinks to both human and Digimon alike. He want Veemon and Gatomon fall in love. In the movie, Kamemon play with Veemon and Gatomon in swinging play ground. He likes to eat kinds of food and drink green apple juice. He falls down with his shell like Squirtle in Pokemon. He gave Armadillomon a sandwich nicely.
- Met Knuckle: Rushing towards the opponent by rolling the ball on his stomach, and knuckles by the helmet on his head.
- Pointer Arrow: A secret compartment at the top of his helmet opens up and a green arrow shaped missile is fired at the desired target.
- Cora Guard: Hides into his body-armour and rebounds the opponent's attacks.
- Cora Attack: Butts the opponent with his head.
The name "Kamemon" refers only to the Rookie form of this Digimon. Kamemon can Digivolve into several more powerful forms, each with a different name and special attack. The vast majority of his time is spent in the Rookie level.
MetalKoromon is Kamemon's Fresh form. The name "MetalKoromon" comes the Japanese word "Metal", which means 'metal' or 'koro'. He can be seen in Rodney's flashback of when he and his partner first met.
Gwappamon is Kamemon's Champion form. Kamemon first digivolved into this form in movie 10 to distract and stop Diaboromon. When Omnimon went back into the Internet to deal with him again and, with some help from ExVeemon, Angewomon and Gawappamon (who held Diaboromon down), Omnimon blew off his head and he was destroyed for good.
