I have an idea @Masterking2
How about a guy that can control water but usually bloodbends and has a scary like face and he has never seen his reflection at all, people are scared of him wherever he goes, he thinks they respect him. When he finds out he was a lab experiment and his "parents" are training him to be a weapon for war, he runs away but he finds a time travel helmet and he is cornered so he time travels at a random place and he ends up in China in the 1600 AD's. His time travel helmet gets stolen and he has to complete a series of challenges called the tournament to get back his helmet, what he does not know is that all the other people participating also have enhanced abilities, The protaganist gets paired up with a character that is weak. They bond and the main character finds out that the weak character's powers are freezing the minds of people for a short amount of time, the weak part is that he doesn't have a way to kill people when they are frozen, he can only use his fists, he's too poor to get any weapon, so our main character gives him a gun and tells him how to use it. Then we find out the weak character wants respect, he does not want the reward when he wins. He thinks if he wins this tournament, he will get respect to the main character will tell him how to get respect. When the challenges start, people who come across the main character die a brutal death so the people in the challenge stay outta his way. The main character tells the weak one that this is how you get respect, people are extremely obedient to you when you do stuff like this, the weak one replies with, they don't respect you.. They fear you. That night when the first challenge is over, the main character looks at a pond and sees his reflection for the first time, then he whispers to himself that he is really a monster.

Thinking of the rest of the story rn.
