[MCU] Are there copycat heroes?

So I was watching this movie called The Dark Knight and in the beginning a bunch of dudes who have no business fighting crime dress up in hockey pads and try to do what Batman does. Does this really happen? Are there guys trying to build Iron Man suits in their garage or trying to get superpowers to be like the Avengers? What happens to them? Any memorable stories?

It's happened a few times, but in the MCU you can kind of sort of get *actual* powers if you try hard enough.

Consider a young Peter Parker who tried to stand up to the combat drones when he was like 8 years old wearing a Halloween mask.  Six years later he's swinging around on webs.  

Karla Gideon grafted scalpel blades to her finger tips and used them to protect herself from her abusive boyfriend.  After she killed him she went crazy and went on a murder spree.  SHIELD categorized her as "enhanced".

Calvin Zabo made his own super soldier serum by mixing a bunch of weird things together, like gorilla testoserone and peppermint, to become super strong.

Trish Walker really, *really* wanted superpowers like her adopted sister.  She spent her life training in the martial arts and ran across combat enhancement drugs a few times.  Finally she forced the guy who gave her sister powers to give her some of her own.  We have yet to see how that plays out, but it looks like she's definitely got heightened reflexes now.
