Background Characters you'd like to see again

One thing that alternately annoys and amuses me about comics is how background characters that are relatively important at some point just kind of disappear because series get cancelled or creative teams change or things like that.

And it's a shame because a lot of those characters are legitimately awesome. Buck Wargo, anyone?

So I was wondering, what vanished minor character would you like to see again? (It doesn't matter if they just disappeared, or got killed off, or anything like that because, hell, it's comics.)

For me, it's Buck Wargo from Warrior. Because nothing beats an awesome millionaire scientist cowboy who actually serves as a functional father/older brother-type figure for Guy. Also, probably the single greatest author-avatar character ever.

A runner up character I'd like to see again is Dawn Fury. Her few appearances in Howling Commandos were fairly awesome!

But as far as I know, she's never appeared in any comics set later than WWII. Which sucks because Jake Fury got to be a damn supervillain, and Jake was a tool. Dawn seems like she'd be fun to just add somewhere, maybe to SHIELD since Dugan and Jones are pretty clear indications that Nick likes nepotism.

It'd be funny if she were like a SHIELD psychologist or something. Just because I'm intensely amused by the idea of a Fury who's also a shrink.

So what minor and disappeared character would YOU like to see again?
