okay how about lowering the speed to something that is actually physically possible, like rivaling a car, get rid of the energy beams until later notice, increased strength only to equal that of an amatuer weightlifter for inproportionate body strength, make the head only about twice as dense as a regular humans, as in able to stop a slow moving bullet, and pull the expert swordsman back a bit two silver medal fencer. You've got to have something to build up from, so eventually you can get up to tha level...while were at it, have the entire teleportation thing have a bi t of a drawback to begin with, like within range of sight, only in times of extreme mental stress, and/or extreme feeling of inertia.
