i just imagined teleporting people had pocket dimensions that stored any of that energy so they could tap ibto it for big jumps,(reply>), @Wolfrover there is still the energy needed to go up or down. does his little dimension provide and store that energy,(reply>), Some do.  Marvel's Nightcrawler, for instance, is a short-range teleporter at least partially because he's actually switching to another dimension, walking to the appropriate point in that dimension, and switching back.  That gets problematic over long distances, however, due to potential differences in terrain.
