List of Mega Man characters
Lumine is the main antagonist of "Mega Man X8". Due to being a new generation Reploid, he can transform into other Reploids. Lumine is introduced as the director of the Jakob project, the Orbital elevator in the beginning of X8. He was soon kidnapped by Vile, due to his knowledge of the elevator. After defeating Sigma (originally thought to be the instigator of the events of the game once more) on normal or hard mode, Lumine is revealed to have been manipulating a weakened Sigma this time around, though he really means that he is essentially Sigma himself, and is carrying out his plans. He knows that Sigma could not do what he did in the whole series forever. He goes onto claim that this was Sigma's final death and that would be unable to return.
