A Dinosaur Digimon whose body was eroded by a malicious computer virus. Originally a Tyrannomon-type Digimon, DarkTyrannomon was infected by a malicious virus that caused the data composing its body to bug out and transfigure it into a frenzied creature. Its body has been dyed black, and its arms have grown even stronger than those of Tyrannomon, increasing its attack power. DarkTyrannomon has become absolutely ferocious, and treats everything its eyes spot as an enemy to attack. It uses its special move Fire Blast to shoot a super-powerful flame that transforms the surrounding area into a sea of fire.
