As pointed out, it seems he is corrupted, with odd scars on his body. Could this be
- "the first clone" (maybe even the new Match)
- the eradicator
- Cyborg Superman; His name begins with an H, what if he later adopts the name "Hank" after getting cybernetic implants after being seriously injured or degraded? -> a stretch, i know
- A replacement/amalgamation of 2 or more of these characters?
Or do we get a new villain altogether before some of the old favorites return?
