I'm writing a novel, The Change Storms: Induction (I'm ~60,000 words in, and you can read it for free on my Patreon). The idea is to answer the question "what would the world look like if superpowers were real and contagious?" Answer: there would be no spandex, and there would be a lot of internment camps.
I'm looking for suggestions on superpowers, ideally ones that are physics-based. I have a bunch of ones that run on phlebotinum (one of the main characters has "powerful telekinetic, but only with things that are triangular"), and I'd like to try doing some that are along the lines of 'in a 1L volume, the strong nuclear force becomes repulsive instead of attractant'. I checked that one out over on /r/askphysics and the effect turns out to be "a massive sleet of ionizing radiation that kills everything in the area" so I decided not to do it.
All suggestions are welcome, regardless of their physics ones. Links to similar threads are also appreciated, although I've trawled a lot of such things already.
