I've got three on my mind, now please hear me out: Waluigi, Mona, and Travis Touchdown.
I know that Waluigi's been in just spin-offs, but you can seriously base a moveset off of all those games. Like the Up-B could be temporary flight like Pit's, but it would be with him swimming through mid-air. Here's what else I thought, it's kinda like PT: he has three weapons, a tennis racket, a golf club, and a baseball bat. B would be your basic charfe-up smack, with different damages and reaches for each one. Forward-B would be that he takes the respective ball for each weapon and hits it. The tennis ball would go higher rather than farther, the golf ball would go straighter without much height, and the baseball, would arch inbetween. Down-B would be swapping between them in a cycle, and your A moves wouldn't change with your weapon, just the slight damage and reach change. Final Smash? Dance of Destruction, of course. Akin to Luigi's Negative Zone, Waluigi starts dancing, but instead of a bubble of death, explosives rain down for a short period, like what happens in a Sudden Death.
I chose Mona over Ashley because I thought she would be more versitile. Having many different jobs all the time gives her alot of options to choose from. I'm with this guy's ideas: http://angstyguy.deviantart.com/art/Mona-s-Moves-36236311
Seriously, if you can put in Solid Snake, and you have beam swords as an item, you should have no problem with Travis Touchdown. I know alot of people would probably start the whole "we have enough sword users in Smash" crap, so I'll just say something cheesy right here: it's not a sword, it's a beam katana. But yeah, you've got a bunch of wrestling moves for any grab you can think of, and he even has a projectile. I say put him in.
So, what do you all think?
