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
Lord Wily can be seen as the primary antagonist of the Battle Network franchise. He himself appears as the main villain of "Mega Man Battle Network", "Mega Man Battle Network 3" and "Mega Man Battle Network 6". He manipulates Sean Obihiro into leading the NetMafia Gospel in "Mega Man Battle Network 2", and his son Dr. Regal is the main villain of "Mega Man Battle Network 4" and "Mega Man Battle Network 5". He becomes jealous when his robotics research is pushed aside in favor of Tadashi Hikari's breakthroughs in network technology, and devotes his life to destroying network society. "Battle Network 6" reveals that, for a time, Wily had put aside his thirst for revenge; however, the death of Baryl's father caused him to reconsider.
