Impmon is a playable character in Digimon Rumble Arena. You can’t use him at first. You have to beat the game with all of the season three characters, Renamon, Terriermon, and Guilmon.

Impmon's attacks are Summon and Bada-Boom. He's, in my opnion, the strongest Rookie, and can beat Reapermon easily with the use of Summon. He digivolves to Beelzemon, and his attack sare Darkness Claw and Dark Laser.
