Has Captain America's shield, which one of the materials used in it doesn't exist in the real world.
Large Gym is starting location.
Everyone should be able to stomp the clones with ease. All you have to do is use the fact that there is a large amount of distance between you and the clones, and run like hell, taking the shield with you. Quickly find the nearest military base or whatever, and pawn it off to the government. Use the money to then temporarily hire the same government people who you sold it to to KO the clones, then sell the clones to them as well. :P
