Negatron

Negatron (voiced by David Van Horn) is a three-eyed Nighlok with a smart mouth and a unique battle style: tormenting his foes to a series of insults that are so harsh that the emotional pain becomes physical. His insults however, have no effect on Emily, as she has long since taught herself not to let insults hurt her. He is not a very good fighter and relies heavily on his 'insult' powers.
