What is a boy name that means changeling?

Transformo> which also suggests an electrical appliance- you know Ac to Dc, altering the voltage, etc. That is the only one I could think of. Prometheus, maybe, but that is a different sort of character, the Titan ( not usually depicted as a Giant man, though) who stole fire from the Gods to help mankind- there is a statue of him with a large golden-brass ring , at Rockefeller Center. The Ring may symbolize gravity or the orbit of the earth. sorry,cant help you. Transformo sounds like some comic-book super-heroe, but I can"t recall one with this handle.
