Ok I got a good one check this out. As you know Mimic can only copy 5 power sets at one time. So what if he copied Madrox that means Mimic can make at lest 25 duplacates of himself. Now all of the duplacates have the same Mimic power the real one has and every Mimic duplacate copied 4 power set of different mutants. so then the real Mimic pulled all of the duplacates back into himself then all of the power sets the duplacates copied are his. is that even possible?
Real Mimic - Madrox, Deadpool, X-Man, Beast, Cyclops + Duplacate Mimic - Jean Gray, Vulcan, Colossus, Wolverine, Madrox = Real Mimic - Madrox, Deadpool, X-Man, Beast, Cyclops, Jean Gary, Vulcan, Colossus And Wolverine. Now thats just 2 but I think you get the idea.
