Nega Beast Boy is an evil clone of Beast Boy created by Trigon.


Since Cyborg, Starfire and Beast Boy are protected from Trigon's powers thanks to the Ring of Azar, he refuses to expend more of his energy to destroy them and uses his powers to extract the evil sides out of each of them and pits them against each other, each against his or her own clone.

Nega Beast Boy matches Beast Boy form for form, but Beast Boy holds his own quite well. Shortly after, Nega Beast Boy taunts Beast Boy by reminding him of Terra's duplicity. Nega Beast Boy says that Beast Boy is weak, and that's why Terra betrayed him. Beast Boy fights with even more vigor then before after this comment, with tears in his eyes.

Later, as the tide of the battle above ground starts to turn against the Teen Titans, they decide to switch combatants in hopes of regaining the advantage. Therefore, Cyborg fights against Nega Beast Boy and easily beats him by a punch. He then evaporate into wisps of red energy that return to Beast Boy.


  • During the battle, Beast Boy turned into a Tyrannosaurus Rex and Nega Beast Boy turns into a Spinosaurus, and the resulting battle resembles a scene from the movie Jurassic Park III.
  • Nega Beast Boy and the other evil duplicates of Cyborg and Starfire weren't destroyed after they were defeated, but instead returned to their counterparts' body. This is because Nega Beast Boy wasn't a clone of Beast Boy, but rather the "bad side" of him that he always had inside himself.
