[@ERode] Haven't really decided yet but the plan was more teleporting downward at the peak of the jump so he doesn't fall as far rather than just warping at the last minute to negate fall damage. Although that does fit the video game glitch aesthetic.

Momentum cancellation via your quirk does add a new level of power to it.  Good for defense (like your falling) but also knock back.
