When they finally come to destroy the earth (they'll have to go through you first)

When they finally come to destroy the earth (they'll have to go through you first)

Kind of stupid name. But in light of my previous post, this is the Tony Stark & Bruce Wayne friendship story you were always wanting. There's Tony and Steve pre-slash, but I especially liked Tony instantly identifying Batman, and Bruce learning to be a playboy billionaire from Tony, and Alfred and Bruce reacting to the "I'm Iron Man" press conference. The whole story is just a joy for the fan of both franchises.
