creating respective orange and blue portals with my hands, that link to each other
i think there was a game made about this, or two.
compared to teleportation:
pro: can assist others in teleportation, rather than just myself. i can also please a certain group of fans with my amazing power
cons: i have to have line of sight on my destination
and before you say "you would also die if you do any velocity jumping", teleportation is equally dangerous. You could accidentally teleport in a wall and instantly die.
plus i would be able to go places a lot faster :)
