Omnitrix force in marvel

I do not own Marvel or Ben 10. I came up with this idea while reading Ben 10/ Marvel fanfiction or novel. If there is already a novel or fanfiction about this please let me know as I will take this down as long as a different person came up with this idea before I did unless he or she allows me to continue this. Long story short: A guy reincarnated into Marvel mcu with an Omnitrix. He decides to make a force composed of only himself and his aliens in the Omnitrix. He makes it seem like he was chosen to be a part of their force that is composed of many different aliens. when in reality he is just having fun being a hero and getting shield and the other heroes worried about a huge alien force with the potential to invade Earth. Note: As of now this is only an idea. If I decide to start writing chapters do know that it will likely not be often. If someone wants to take over this idea and start making chapters I would allow it, but if multiple people want to do so, then I would be fine since I would like to see it as a multiverse where and you guys, gals, or both can make a chapter from two different viewpoints where the MC's interact with each other. Please do let me know. But if you decide to end it or put it on indefinite hiatus. Then I have full permission to allow others to either continue from where you left off in their own novel or fanfiction and make it a near identical universe where the two MC's did the same thing until that point in time and it changes from there. The cover is not mine. If it is yours and you would like me to take it down. Please let me know and I will do so.
