Nigeris Prime

Nigeris Prime is the leader of a special resistance force known as the Iacon Rebels. An ex-Autobot Colonel, he was one of the few Autobots to have been deserted on Cybertron after the "Ark" and several other evacuation ships took off, leaving them behind. Now, neither Autobot or Decepticon, he lives in exile, plotting assaults on the Decepticon sector surveillance squad lead by Shockproof (NOT Shockwave).

Personality
Nigeris Prime is a brave, charismatic leader, always removing himself from the equation, just so he can get a few explosions here and there. Some say however, that he has gone soft; he is friendly and very cheerful around "lesser" beings and "organics". This note has been ignored on several occasions, and he is indeed headstrong and cunning like most known leaders on Cybertron.

Reputation
Nigeris' name has been hindered as an insult to Decepticons, who have time and time again been thwarted, tricked and killed by the Rebel. Shockproof sees him as a "pile of old parts that should be recycled into a cleaning utensil". Optimus Prime, leader of the Autobots personally contacted him on many occasions, congratulating him and his rebels on their countless successes and fights against the Decepticon menace, and even offered him and his team (despite some of them being Decepticon rogues) to join him in his resumation of Autobot activity elsewhere across the universe, though all times have been honourably declined.

Shockwave, the designated ruler of Cybertron as Megatron has transported to Earth, does not think too much of an impurity among his kingdom, which is why he sends Shockproof, his most annoying subject to dispose of him.
