Billy Numerous is a former student of the H.I.V.E. Academy.

Billy Numerous has the power to duplicate himself as many times as he wants. His clones are effectively all independent entities who share both Billy's personality and duplication powers. The exact numerical limit of clones he can effectively create is unknown, though it ranges well beyond a hundred. If Billy overtaxes his power, however, all the clones will forcibly re-merge with him, which will lead to a massive shock to his system.
