Option 1:

In a cold dark world, a hero emerged called Louis Belanger. He was born tall with dark hair. He outgrew his native planet to live in Canada, which he later renounced to join France. There, he stood tall to defend the rights of hockey player that sucked like @HillsHaveHats . He needed to make sure that even though these players could not be proper hockey player, they still believed they could. Unfortunately, Oliver grew jealous of Louis and travelled from England to Louis's native planet to become a villain taking on some powers that Louis had, this is how Oliver had the skills to play in the SHL. Doing this, he became Louis's kryptonite. Louis only had one weakness on the ice and it was to see Oliver in his locker room before a game. When that happens, Louis needs helps breathing so he doesn't destroy Oliver with his superior brain and physical strength. This explains why Oliver has to change alone in a dark locker room before each game.
