Starmon

Starmon is a Champion Level Mutant Digimon that is said to have born from the data of a space exploration software. He only fights for justice and is partners with Deputymon.

Digimon Adventure 02
Starmon first appeared as a sheriff of a ghost town in the Digital World. He was a victim of the Digimon Emperor's Dark Ring and locked Biyomon up in his cell. He later imprisoned Davis, Yolei, Cody, and Sora along with Veemon, Hawkmon, and Armadillomon. After Starmon left, Deputymon appeared and freed Sora and Yolei so that he could play cards with them. When Starmon found out from Davis and Cody, he went after Deputymon, allowing the two to escape. Starmon found Deputymon and brought him down with his Meteor Shower attack before being sent flying into the Control Spire (disguised as a water tower) by Flamedramon. Starmon was freed from the Dark Ring and he and Deputymon played cards with them. Later, a Starmon was among the Digimon seen during the final battle against MaloMyotismon.
