While Powers in this game are limited really by your imagination and your willingness to to do math, a few obvious categories are worth describing in some detail.
Super Normal - one of those people who's naturally good at everything.
Super Stat – a basic Stat or other ability elevated to superhuman level.
Rule Exemption – where a particular rule does not apply to the character
Special Status – such as undead or robot
Artifact based - powers granted from Props.
Cybernetic Powers - or other implants or prosthetics.
Psionics - powers that come from your brain.
Magic – which gets weird quickly
Miraculous Powers - where some outside entity is helping.
