Tony & Hulk Friendship + Super Villain Tony

[dls_fandom]

Hi all,

I'm looking for:

1) Fics where Tony and Hulk are friends - either them hanging out or Hulk being protective or Tony calming down Hulk. I've read snippets in bigger fics where Hulk considers Tony a friend but usually in passing only.

2) Fics where Tony is a super villain (because let's be honest, he could totally and easily conquer the world as Tony Stark).

Thanks in advance!
