Nega Beast Boy is a villain in the Teen Titans episodes "The End Part 2" and "The End Part 3". He is an evil clone of Beast Boy created by Trigon.


Since Cyborg, Starfire and Beast Boy are protected to 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 create evil clones out of each of them and pits them against each other, each against his or her own clone.

Shortly after, Nega Beast Boy taunts Beast Boy by reminding him of Terra's duplicity.finding his weakness saying no wonder why she dumped him which crush beast boy feelings which mocking him saying Did he hurt his feelings.

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.
