i remember coming up with one once, the ability to flash step, like teleportation, but it uses up the same amount of wear and tear on your body(and clothing/footwear) and stamina as if you walked a straight line there (say you were Stepping to the top of mount everest, the same amount of physical exhaustion and bodily wear and tear as if you tilted the earth, laid a flat board to the summit, and walked across it, and untilting the earth, all in an instant). where the only convenience obtained is time saved, but there would also be the issue of being constantly exhausted, the near limitless amounts of food needed to be consumed, and the constant need for sleep would make this power essentially useless except for convenience, you COULD say this is similar to stopping time, but with far more limitations, as its only used for moving from one place to another
