Aliens are actively abducting people and jacking them up cybernetically and shooting them up with gene boosting serums like in Deadpool then wiping their memory.

Check out this alien implant on my ankle. The scar tissue is my doing I tried to cut it out but it has its own blood supply and I have another in the back of my skull so I left it.

I have no idea how you volunteer for these kind of enhancements and experiments if you'd want to.
