In Alien Force and Ultimate Alien, Octagon wears an orange-black jacket, red overalls, orange hat, and black gloves, belt, and belt pouches.
In Omniverse, Octagon looks slimmer. He has an oval face, different jacket, and orange gloves. His orange hat now has goggles on it.
Octagon has quite a large vocabulary, and can say things that are quite deep, but despite his more mature, serious, and down-to-earth personality, he can still be easily distracted, such as when Gwen distracted him and Rhomboid with bubble wrap.
Octagon often finds himself at odds with Rhomboid, while he often attempts to talk or negotiate in situations, Rhomboid will start blasting away before he can really get talking.
Powers and Abilities
Since Octagon is somewhat smarter than Rhomboid, he could be considered as the strategist, while his brother provides the muscle. What he lacks in brute force, he makes up for with tenacity and is able to use a wide variety of weapons.
Octagon can survive in space.
Like his brother, Octagon has a form of immortality as his memories and experiences are always transferred to a cloning chamber whenever his present body is destroyed or he otherwise dies in some manner. How many times this has actually happened is unknown, but Octagon has admitted that sort of situation has occurred on a fairly regular basis.
Though he is a bit more intelligent than Rhomboid, Octagon's criminal plans normally backfire due to the fact that he doesn't think things through enough, nor does he consider any consequences. This usually leads to him and Rhomboid being blown up or killed, only to be resurrected with new cloned bodies. Typically, they do not learn from their previous mistakes.
Like his brother, Octagon can be easily distracted, (such as with bubble wrap), and he has a deathly fear of his mother, Ma Vreedle.
