Imperialdramon has gone on a rampage. Shadows have taken over Imperialdramon's heart in its Dragon Mode (Black), transforming it into a draconic warrior form with the Virus attribute. It abhors Digimon of the Vaccine attribute, and specifically pursues Digimon belonging to the Virus Busters to eliminate them.
In addition to being able to shoot the Positron Laser equipped on its left arm, it can utilize the heat sink with its Positron Laser Lance in another strong attack. Also, by inserting the Positron Laser into the dinosaur head in its chest, it can increase its offensive power by an unfathomable amount by releasing all of the energy in its body as a destructive wave of energy called Giga Death.
