IMO only as the base that is like Accelerator, as soon as he in get in a class he is different, Lunatic Psyker look like a strong man, a brawler, which is not much like Accelerator, Mastermind is well dressed intelligent looking man that have a entirely different hair style, and Diabolic Esper is the closest to Accelerator but he feel twisted in a different way than Accelerator.
the art here shown Lunatic Psyker classes but it not very well drawn IMO, look at the official art.
