Juan’s a master of motion, light on his feet with unique climbing & supernatural teleportation skills: he’ll come out of nowhere! His katana can kill the entire bill if he gets close enough. O.P. may be the no-gun assassin but those ninja stars aren’t toys, watch out now!
Juan is a ninja warrior, he has a sword, capable of applying bleed, which does a damage over time. He has shurikens, and has an amazing dps. He is considered Overpowered and OP By many, and even in his name is "O.P." I guess he's meant to be this way.
