Dynamic Powersets: Do they exist?
I've seen lots of talk on the forums about "Dynamic Powersets" as applies to certain characters, that is to say that certain characters are able to climb in and out of rigidly defined power tiers when the need arises.
Here's my question: do dynamic powersets exist or are they merely abstractions created by posters to rationalize ultra-high-end showings that are obvious outliers? Case in point: Superman lifting (with Captain Marvel's help) a book that weighed more than the Universe in FC: Superman Beyond.
Was this an example of Superman's dynamic powerset coming to play or was it just a one off fluke?
Personally I'm on the fence.
