Freeze time, I mean if we all fought each other with our powers the people who could freeze time would win. Walk away learn how to make a nuke, nuke the area where you all are.
Freezing time is better than invisibility cuz: If you were hiding in a closet (just an example lol) and you heard/saw the person then you could freeze time, open the door, exit and close the door.
Better than knowing everything too cuz you could freeze time, learn everything and start time again.
The possibilities are truly endless.
