|“||Yikes! Aah! My insults backfired!||„|
|~ Negatron’s final words before his destruction.|
Negatron is a three eyed mouth/insult themed Nighlok with unique battle style: tormenting his enemies to a series of results and emotional pain becomes physical. He serves as the main antagonist of the episode "Sticks and Stones".
Negatron was one of Nighloks. He possessed unique ability to torment his enemies to a series of insults and emotional pain becomes physical. In the sixth episode Negatron arrived at Master Xandred's Junk and told that will fight the Samurai Rangers. Dayu didn't like Negatron.
She considered him a loser who can only abuse his enemies. Then Negatron attacked Panorama City and at first abused Bulk and Spike. Then he encountered the Power Rangers. He easily defeated Rangers with his insult attacks, but his ability didn't work on Emily, because she taught herself in the childhood not to let insults hurt her. Then he left.
Nighlok returned to the junk of Master Xandred and "trained" his ability on Dayu, making her angry. Then he returned to the city and again battled the rangers. Now Emily defeated him and Mike shut his mouth with stones and Jayden destroyed him with Fire Smasher in bazooka mode. Then Negatron returned as Mega Monster and could fire lightnings. He was again destroyed by the Beetle Blaster Megazord.
Negatron later attended a Halloween party at the Nighlok Heaven. He recounts his battles with the Samurai Ranger.
Negatron was arrogant and confident Nighlok who enjoyed his ability to torment his enemies emotionally. He was angry when Emily resisted his insult attacks and finally defeated him.
