I'm also thinking about the taunt(s). There's a lot of good ones to choose from both aesthetically if I wanted to go cool taunt wise and funny if I wanted to go meme taunt wise. So standing and crouched will both have their own taunts!
I think standing will be an over dramatic salute, like Samus's taunt from smash. Or something cool like that.
I'd love to have crouching taunt be a Ghost Stare reference. But idk how to get that to work under these conditions... These mfs ain't got any eyes or any facial features for that matter...
