Those Upon Whom I Look

Let's say, hypothetically, that I've written an Avengers fic that's a complete AU (although one based on 616 and the MCU, characterization-wise, at least). One where the various characters know each other because they're on a team in a MMORPG that's along the lines of WoW or something similar.

Now, the characters' real names are just going to be their, you know, real names. Steve Rogers. Tony Stark. Carol Danvers. They'll also have names in-game, though, ones that will fit with the fantastical setting but still be reminiscent enough of their superhero identities to make it obvious who they are.

The problem is that I'm still trying to think of in-game character names. :-/

Right now, I have their names listed as [Steve] and [Tony] and the like, so that I can easily replace those names with whatever I decide on. I just... haven't figured out yet what I've decided on. And, you know, I could use some help, if anyone has suggestions.

The characters who make appearances in said fic (or, at least, are mentioned) are as follows: Bruce Banner, Bucky Barnes, Carol Danvers, Clint Barton, James Rhodes, Janet van Dyne, Jessica Drew, Natasha Romanova, Pepper Potts, Steve Rogers, Thor, and Tony Stark.

With some of them, their superhero names (or lack thereof, in the case of, say, Thor) would probably fit well enough that they wouldn't need to be changed. With others... not so much.

So... any suggestions?
