Ridley (Metroid)
Ridley returns in his Meta form once again in "", where he, along with the Space Pirate legion under his command, are corrupted by Dark Samus. He encounters and battles Samus on Norion, a Galactic Federation-occupied world, and the two fight while free-falling down an air shaft. Ridley is later supercharged with Phazon, becoming "Omega Ridley", and is charged with guarding the Leviathan Seed on the Space Pirate homeworld. He is confronted once again by Samus, and despite being defeated, he survives the fight and is later cured of his corruption after Dark Samus' defeat later on. Between the "Prime" trilogy and "", the Space Pirates reorganize on Zebes and hatch another plan to clone and weaponize the Metroids, while Ridley gradually begins to regenerate from his past injuries, gradually shedding his cybernetics. In the remake of the second game, "", Ridley, in his semi-regenerated form of "Proteus Ridley", attacks Samus on SR388 to steal the last remaining Metroid. Samus and the baby Metroid work together to defeat Ridley.
List of Ben 10 villains
Octagon and Rhomboid Vreedle are a pair of "Repo men" who happen to be the sons of the infamous criminal Ma Vreedle, having very limited intelligence and theirs occupation includes bounty hunting and mercenaries for hire. Octagon is the older brother, slightly more intelligent with more mature, serious and down-to-earth personality, yet can still be easily tricked such as when Gwen distracted him and his brother with bubble wrap. Rhomboid is the least intelligent of the siblings who is the brawn of the two with a habit of always blowing things up with a large weapon. As he is the younger brother, despite being larger in size, he usually follows Octagon's orders with occasional foul-ups on his end. The Vreedle Brothers are physically weaker than most of Ben's enemies and appear to be no stronger than a normal human. However they make up for this with a large arsenal of various Alien weapons; and have a tendency to blow things up, which results in them having numerous run-ins with the law. The Vreedles are revealed to be multiple clone pairs created by their parents using an "expired cloning kit". Despite being basically defective clones, the Vreedles have a form of semi-immortality, meaning even if they are killed, usually by explosions they caused, their memories are transferred into another "set" of clones who will take their place.
