Doctor Greyman looks like a typical alien, with grey skin, and large dark eyes, along with dark purple eyelids. He has a slim build and no hair. Although his body is mostly naked, he wears a dark blue fedora hat, with a purple scarf, a long white beard, long light blue socks, and blue shoes.
He now goes around in a floating, white wheel-chair, with purple cushion. He still has his dark blue fedora, but he now has a fake white beard (as seen in "Final Exams").
The full extent of his personality has yet to be shown, but it can be assumed that he is more cautious than the others by the way he reacted to Foxtail's reckless driving. Going by the traditional depiction of aliens, it can also be inferred that he is the brains of the team. This claim is further backed up by the fact he was the one to handle the test scores and portfolios during the induction ceremony.
He seems to be somewhat of a carefree person, acting in a friendly and casual way towards his teammates. However, he is serious about fighting crime much like the other members of P.O.I.N.T.
Abilities and Powers
In "Let's Take a Moment", a flashback shows that, while young, he has lost his powers due to a mysterious weapon. In "Bittersweet Rivals" it was again stated that he has lost his powers, and in "Final Exams" Foxtail calls him "powerless", making it clear that the effect was permanent.
Doctor Greyman's exact power level is still unknown, but he was powerful enough to be one of the three top members of P.O.I.N.T.
Levitation Skills: Much like Rad, Greyman could shoot beams from his fingers that could levitate objects or even himself, though, his beams were aqua-green colored.
