Batman (OTR's Version of the past)

Batman is a super hero-in training. He travels through time into the future where he joins Batman's Super Squad. Luckily when he travels, the time in the past is frozen, so when he comes back physically no time has passed at all. He is at the point in his life where he's still not yet Batman, but he is training. Being this as so, he receives training (along with his future sidekick Dick Grayson) from his future self Batman. While past Batman is not aware Batman is his future self, the Batman of the future is aware that he is but doesn't say anything about it. The only people who know this Batman is the Batman who is leader are the present Batman, and the Joker (which he reveals to past Batman in the final comic of the Batman's Super Squad series).
