Can someone tell me when and how Chamber got his powers back? I thought he had a gaping hole in him again and was being treated by Kativa? I know previously he was shown to be a descendant of Apocalypse and had a new look. But I know he reverted post Age of X. When did he re-power?
I know he's there to play up the Apocalypse connection (also he looks cool), but I think it was an oversight. Thoughts?
