Storm trance is no different than other supers. If you see them coming from a distance you can try killing him before he reached you or run. If they activated the super close to you, there's a small window were you might be able to kill them quick. But unlikely. Storm trance is a little different because it doesn't kill you instantly like Nova Bomb or Fist of Havoc. So you do have a "slightly" better chance than you do versus other supers.
