Biological Manipulation (self) – This is the ability to control one’s own biological make-up. Biological Manipulation (self) is also known as Anatomy Manipulation, Body Manipulation, Corporikinesis and Self-Manipulation.
The DC universe has had some really interesting examples of self-inflicted biological manipulation.
Krypto (DC) turned into a female collie due to red kryptonite (Superboy V1 #101). Krypto was thinking about a female collie at the time so Krypto did have some control over his transformation. How he/she has puppies without sex is not explained in typical Silver Age manner.
Lois Lane (DC) becomes a black woman using technology in Superman’s Girl Friend V1 #106!
Jimmy Olsen (DC) gets muscles in Superman’s Pal #73
