There are a lot of reality benders out there, and I'm surprised that there isn't a tag for it somewhere. I was thinking "Let me get a whole list of them and see if this could be a tag."
Turns out: The list I just posted has only 10%ish of the reality bending SCPs. Using a quick search, there are 393 results for articles with "reality bending/reality bender" that are SCPs.
So yea, tag proposal: Reality-Bending. Anything that explicitly bends reality/reality restructuring event in the article.
THIS TIME WITH MORE FIRE!
