・Kalypso Bite ・Iphigenia Pierce ・Dead End Spike ・Gran TrES
An Evil Dragon Digimon that plots to rule through rage and fear. As an Ultimate-level Digimon, Regulusmon boasts power reminiscent of Megidramon of the famed Four Great Dragons, and its advent alone spells disaster. Its body is the source of the "GRB (Gulus Realm Burst)" 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.
As for Regulusmon's special moves, its Kalypso Bite technique sees opponents seized by the jaws of its left arm's shield, while three penetrating lasers are fired from this shield during its Iphigenia Pierce move. For Dead End Spike, Regulusmon stabs foes with its two-pronged tail. Lastly, in its most threatening move, Gran TrES, Regulusmon 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.
