Steve, Tony, Peter, Quill, Clint, Scott, Bruce, Wade, Wilson, xavier, Charles, Logan, Eric, kurt, Henry, Hank, Phil, Luke, Nick, plus a ton more of more regular names too!
Or, go down the really different and go for something like Drax, Storm, Magneto, Maximof, rocket, Cyclops, or Thanos. I'd really not recommend any of those, your child will get 
looks their whole life!
Thanos is a normal Greek name I believe although I'd say its pretty rare in the UK!
