1 What if "Jumper"

Ok this is the "What If" idea

In an alternate world of earth that everyone at there birth will receive a unique skill that as long as you're alive will not appear to any other person other than you and as long as you keep training your skill to higher lvl you will get a ability connected to your unique skill. And here is the plot you're Mc's unique skill is jumping and everyone thought of him as a useless,retarded, and idiotic person because of it and the other reason is that he still training his skill to higher lvl's even though it's only a skill about jumping but at a certain day he finally get his skill to the max lvl and gain the ultimate ability of his unique skill and that is "ULTIMATE JUMP"- your ability to jump is at the ultimate lvl that you can jump into other reality.and at the same time jump to at a specific time and place you want to be at the moment you jump to another reality you will have the ability to jump at someone and take there body but if you jump back at your own reality you will only get the power you got at that person's body when you were inside it and not there body and features.
