"New character Greymalkin from Young X-Men has this as his origin story. He was buried alive by his abusive father roughly 200 years ago. The trauma caused his mutant powers to appear, and it just so happens said powers are superstrength and invincibility except in total darkness." I thought it was the exact opposite, that total darkness increases his powers rather than counteracts them.
