DC Animation Verse (Harem) x Male Reader

The DC Animated Universe is a vast universe filled with countless heroes, villains, and adventures. And you've become part of it: you're a master of Rokushiki and Haki. The Six Powers are a set of superhuman martial arts techniques. Haki is a mysterious power that allows people to harness their spiritual energy to perform various superhuman feats. You've mastered all the basics (but later in the story, you'll achieve Advanced techniques in both styles). With these powers, you've helped the heroes in a major event and become part of the Justice League, the world's most powerful heroes.
You're a hero, saving people, falling in love with girls who fall in love with you, fighting evil, and saving the world. A dream come true.
