Teleportation. I suppose it would be somewhat limited by the fact that teleporting to a place where other people might be would be tricky, since I absolutely don’t want to be caught.
Even with hesitation to teleport to populated areas, the ability to teleport home would be massively useful as a utility. I could also teleport out of danger in an emergency. I wonder if I pick up a person would allow me to teleport them with me, in which case then it’s got hero potential too.
