|This article is about a/an Nighlok Monster in Power Rangers Samurai.|
Negatron is a Nighlok. He has 3 glowing eyes on his back, one on bottom left, one on bottom right, and one above them in the center. He has spikes on his head. By tormenting its foes to a series of insults, the insults are so bad 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.
- "You lame-brain louses! You just turned me into a Mega Monster!"
- ―After turned into a Mega Monster.[src]
- Negatron appears in Power Rangers Samurai SMASH! as one of the three recurring bosses. His attack involves laughing at the Ranger fighting him. The sonic waves from the laugh takes up the half of the screen where he is situated.
- The insults to injure the rangers except Emily were:
- Mike - That his bike had training wheels until Mike was ten.
- Kevin - He was boring / Mentor's Little Pet.
- Mia - Lousy Cook.
- Jayden - A liar and that Jayden had a secret.
