Ridley (Metroid)
Ridley's status within the ranks of the Space Pirates is unclear, with some sources stating that he is the leader of the entire Space Pirate race, whereas others portray him as simply the Pirates' military commander or even a mere enforcer within the Pirate military ranks, subservient to Mother Brain or Space Pirate High Command. Regardless, he is consistently depicted as a ruthless and cunning tactician who never passes up an opportunity to bring his considerable ferocity to bear on the battlefield, opting to overwhelm his opponents with an unwavering onslaught of attacks from his mouth, claws, and tail. He is also incredibly cruel, actively taking pleasure in the killing and torment of others; at one point in the official manga he taunts Samus by claiming he may have devoured her mother's corpse after killing her, and a Space Pirate log entry in "Metroid Prime" notes that being the mainstay of the Pirate security force is "a job he will certainly relish."
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.
