Power Mimicry – The ability to copy the powers of another being.
Amazo (DC) is an android that copies the powers of the Justice League (DC Who’s Who V1 #1).
The Composite Superman (DC) is probably the first example of a power mimic but absorbs his powers from statues not superheroes directly (World’s Finest Comics V1 #142).
H.A.R.D. Corps (Valiant Universe) can upload one Harbinger power at a time but can switch powers pretty quickly (Valiant Universe Handbook FCBD, 2014).
The Mimic (Marvel) copies the powers of the X-Men but cannot copy the powers of the Super-Adaptoid and vice-versa (Uncanny X-Men V1 #29).
The Super-Adaptoid (Marvel) generally mimics the powers of the Avengers. The Super-Adaptoid like most power mimics can become overloaded (Avengers V1 #45). Amazo and the Super-Adaptoid are both androids. The Justice League and the Avengers are the premier superhero teams of their respective universes. Coincidence?
