Copycat is such a powerful and precise metamorph that she can duplicate another being down to the cellular level. Because of this she is able to replicate superhuman powers, abilities, and even mental imprints so closely that telepaths have trouble identifying her. Copycat simply requires knowledge to duplicate someone's appearance, but needs physical contact to duplicate anything else. Weapon X modified her powers by accelerating the rate at which she could duplicate others. However, as a side effect of this enhancement, Copycat began to lose her memory and was unable to hold any solid form for long periods of time.
