<<Powers and abilities
Copycat is such a powerful and precise metamorph that she can duplicate another being's appearance down to the cellular level. Because of this she can replicate superhuman powers, abilities, and even mental imprints so closely that telepaths have trouble identifying her. However, as a side effect of her copying even brain patterns, Copycat often deludes herself into believing herself to be the one she is copying; when she copied Domino, Vanessa acted nearly exactly as how Domino would have acted in most situations. Weapon X modified her powers by accelerating the rate at which she could duplicate others. >>
