Negatron

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, like " Nice job on inhaling that sandwich piggy!", " Hey roadhog, get of the streets and get some glasses", "Hey nice makeup. You're in the circus!", "Samurai wannabes, you guys are joke!", "So who are you dissing about gossip girls, blah blah blah!", "Your bike had training wheels until you were 10!", "And you Blue Ranger, you're just boring!", "Lousy cook!", You're a red face liar, liar pants on fire. you've got a secret!", "Save more money? You shopaholics could empty a mall and still not be happy!" and "Mentor's little pet!". His insults however, have no effect on Emily, and he is not a very good fighter and relies heavily on his 'insult' powers.

Trivia

 * 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.
