For me the ultimate ability is time control or telekinesis. For time control you could disguise it as teleportation as people cant see you when time is stopped or even actually teleport by sending yourself forward in time to where you want to be without actually going to a future timeline. You can also heal wounds by reversing your bodies time to before you were injured (i got this idea from kurumi from an anime).
On the other hand telekinesis can be disguised as super strength by not using it until you've picked something up (made a whole dnd character around this, he carries an 800 pound sword) and both powers have a wide variety of uses. Time control though is way more versatile
