American Comics: Start with Serum Injection

The protagonist travels to a parallel world where the Marvel Universe is located, with the ability to copy everything. Thor's power? I want. Spider-Man's powers? I want it too. Iron Man's power? I want more. So what about the infinite stones, I copied them for you. No matter what you are, if it passes through my hands, sorry, I can do it all. Thanos snaps his fingers, right? Without stopping him, I watch you do it, and then I do it again, and you do it again, and I do it again. This novel and its characters are purely fictitious.
