Lumine

Lumine is the Reploid that X, Zero, and Axl encounter in Mega Man X8. At the end of the intro stage, Vile "kidnaps" Lumine and takes him away. After vanquishing Sigma in Normal/Hard mode, Lumine reveals that Sigma had fulfilled his purpose (thus, this game is considered "the end of Sigma"); Lumine is the first Reploid to turn Maverick at will. Thus, he is the final boss of Mega Man X8. In the first round, Lumine will be surrounded by 8 colored orbs--the same colors corresponding to the transporters in Gateway, and thus the same powers of the Maverick in said transporter. When he absorbs an orb, he will gain the Overdrive attack and weakness of the chosen Maverick. After his first form, you are transported to "Heaven's Gate", where Lumine transforms into his Seraph form. He does multiple attacks, and in "Overdrive" he, after a few seconds, says "Paradise Lost!" (the subtitle of the game). In that, the sky darkens, and you must defeat Lumine before the screen completely darkens, or you lose a life.
