Dorulumon (Fusion)

Dorulumon is one of the main characters in the upcoming Digimon anime, Digimon Xros Wars, an unoffical member of Taiki's Xros Heart army. While Dorulumon is first introduced in the second episode, he doesn't make a major appearance until the next when he Xros Digivolves with Shoutmon and Ballistamon to form Shoutmon X3. Although he leaves shortly after beating MadLeomon, Dorulumon ends up helping Team Xros Heart again at both the Island and Magma Zones. Though offered a place in the group, Dorulumon turns down the offer because he used to be a member of the Bagura Army. It is revealed by Tactimon that while Dorulumon served under the Bagura Army, he helped destroy and enslave countless Zones as Tactimon's right-hand man.
