There are a many of superheros/supervillains with powers that are shunned and ignored for their lack of manifestation as a contender to normal and we'll known ones. Here are some that I think are underrated:
  1. Memory Manipulation
    "Ability to erase or enhance the memories of another. " Having the ability to change someone's memory to erase bad and scarring experiences, or change their memory of you. For example, a person hates you for some situation that happened between you in the past. You can change how they remember to be neutral, or even positive towards you. Jedi mind tricks much?
  2. Animation
    "Ability to bring inanimate objects to life... " Ever wanted a pet rock? Yeah, that'd be more than possible. Having the ability to raise an army for yourself out of literally anything is nothing to sneeze at. Sentient cars. Living statues. Endless possibility.
  3. Liquification
    "Ability to turn partially or completely into a liquid." Good luck trying to catch a criminal who can liquefy. You'd need more than fingerprints to find someone made of water. Dive into the ocean, and poof. Easy escape. Secondly, last time I checked, turning into water is a good defense mechanism. Liquefying would make you immune to bullets.
