The Stickman ultimate Fight

This world is inhabited by stickmans who have powers and their mission is to fight each other until they die so that the ultimate winner comes out and makes his wish.

These Stickmans have several varied powers. Some good, some bad and some that don't make sense but it doesn't matter since their mission is to fight each other in a clean 1vs1. The most common powers are: Being able to control crystals. Being able to control fire. Telekinesis. Controlling ice. Being good at martial arts or with weapons without even knowing how to use them. Being able to control vegetation. And being able to control blood. Although as I said, the powers are infinite. Most of these stickmans take advantage of their powers to attack defenseless Stickmans who have no power causing a total massacre.

These Stickman types are totally normal. Without any power or gift that makes them stand out from the rest. They are just simple civilians who can die even from a simple shot. These are the ones who resort to dying more by being close to a fight of Stickmans with superpowers or dying at the hands of these same ones.

The most common battlefields are:
"The walled city". "The arena of the forts". "The sacred temple", or even a simple empty battlefield with nothing that could ruin a duel to the death.

The stickmans with powers kill each other and fight since the prophecy says that the last Stickman with powers that remains standing will have a celestial white Crystal appear before him that will open and from it a kind of Milky Way will come out that will transport the "winner" to a dimensional plane that is a representation of space itself and from there a voice that calls itself "The Watcher" will manifest before him and will tell the "winner" that he has been chosen to be the last Stickman standing, after this the voice will ask the "winner" to make a wish. Watch out, only one stickman with superpowers must remain for this to happen.
