Regulusmon

Regulusmon is an Evil Dragon Digimon. It plots to rule through rage and fears. As an Ultimate-level Digimon, Regulusmon boats power reminiscent of Megidramon of the famed Four Great Dragons, and its advent alone spells disaster. It is the source of the "GRB contagion", and it is said that Digimon infected by the GRB factor undergo a twisted change in personality and run amok. However, Black Digitron, the secretion said to cause the blackening, has not been confirmed to cause infections in Digimon who have it in their systems.

 * Dead End Spike: Stabs foes with its two-pronged tail.
 * Gran TrES: Spits out a ball of dark hellfire that swallows all things. Not only physical matter, but even light itself is consumed, leaving not a trace behind. It is Regulusmon's most threatening move.
