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.
