Joe Meach use to be a world famous diver who had been having some bad times he had an idea to make him self known again. His idea was to from a tall building into a tiny bucket. Unfortunatly, the bucket thing he was aiming for had already sprung a leak so he would be jumping to his death. As he lept  Superman came and saved Joe. Joe was mad at what he had done but Superman pointed out he would have been jumping into an inch of water. He was mad at the fact he had no job or anything now. After hearing of his misfortunes Superman too pity on him and offered Joe a job at the superman museum. He had been working their for a while till one night when it was raining and stormy Joe happened to be next to the legion of super heroes statues and thunder had come through the window striking him and the statues knocking him out. When he had woken up he had not only the powers of Superman and the Legion of Super Heroes, but a new persona out to get destroy Batman and Superman.

His name was composite Superman Joe had change half his body to look like batman the other has Superman and his skin color the same as brainiac 5 although all brainiac’s have been seen green. He eventually called the two heroes and asked them to join their team and threaten if he could he would expose their identity. He easily learned their identity by reading the minds. Then batman and Superman had a talk with Superman trying to see his face but composite man had covered it with a layer of lead. They agreed to let composite join them while in reality composite Superman really wanted just to get back at Superman and for some odd reason batman and his side kick robin. He started planning trouble to get to the super heroes one of them was when he turned part of a building to Kryptonite and as it was falling Superman was opposite side of the building not knowing where the kryptonite was and as it fell and people watched while superman struggled to push it up composite came bring back to building. Saving the day and embarrassing superman making him look weak. Next had been with batman and robin late at night as they were watching two crooks try and steal batman told him to stay back and let robin and batman handle this. As composite say batman and robin going down ropes to sneak in he instantly made them to heavy making their ropes to cut as he did so he then stretched his hands out takes the bad guys away and eventually he ended up saving the day. Superman and Batman started getting suspicious of composite superman an as they were planning as he had been a clown in the back ground listeng to them. The later on he had changed into a robin and got in batman’s car suddenly the top had closed on him and robin curious asked what’s wrong. Batman said he wasn’t robin because robin and batman practiced wearing seat belts while driving. The robin turned to composite and said did he really thought he was going get held here flew out while knocking batman out and took him away.
 
Eventually while in his layer met up with superman but before superman had been looking around realizing that composite superman wasn’t just trying to take over the planet but infact the whole dc universe which he most likely would have been able to do. His strength was 3 times stronger then superman and invulnerability in terms of raw strength. He and superman talked then had a small fight eventually with superman only getting one punch composite another and superman getting trapped in a regular ring and composite turning it into kryptonite. He then flew off with superman and batman to lay waste to the two but while flying batman and composite both noticed that composite was flying slower as the moments passed and that he also was lowering down. He then dropped the two heroes and flew back to the museum. Their he was about to try and zap the statues and himself but he ran out of juice and couldn’t then he tried to write on the paper of how he could turn back but stopped about mid way. Mean while superman and batman were falling down to their deaths batman figured that if he pulled the ring off superman he could fly them away from their death he managed to pull the ring off waking superman up instantly from his coma like state and flying the two to safety. Meanwhile in the museum Joe had woken up with a piece of paper in his hand reading what composite superman had left behind for him to see but couldn’t make it out due to the fact that it wasn’t finished leaving the heroes clueless to who composite superman’s real identity was.
