I'd actualy prefer to NOT have the Wasp in an Avengers movie. I've never cared for the character. I bet I could name 20 Marvel female hero's I like better. Hmmm....lets see...

Black Widow, Scarlet Witch, Electra, Black Cat, Invisible Woman, Rogue, Storm, Jean Grey, Psylocke, Shadow Cat, She-Hulk, Medusa, Crystal, Silver Sable, Ms. Marvel, Polaris, Valkyrie, .............well, close!

Notice how many started off as villains? It seems everytime Marvel came up with a great female hero they'd make her turn good. Oh yeah- Mystique- she's good now, right?
