Allistair Roo's hatred for the idea of a Wonderful 101 rep is bordering on fanatic. :lol
Funnily enough, I was taking a trip down memory lane earlier today to see how my wants list changed between pre-Brawl and pre-4 (current time). It seems like I was pretty cool with Lip just for the novelty of her summoning L blocks and dropping them on people, conjuring viruses from Dr. Mario to sic on people and generally representing the Nintendo Puzzle League with a Smash spin.
You do not understand how badly I want this character in. I blame it on watching the totally awesome Kenshin vs. Sojiro fight from Rurouni Kenshin recently, but between that and brainstorming an idea for a "draw and sheathe" swords person for my own pet platform fighter idea, I don't see a situation where a samurai wouldn't bring some hype into the game. For example, I imagine a "gimmick" where one of Takamaru's specials (neutral B) could be dedicated to drawing or sheathing his sword. When drawn, it lets him use nimble sets of slashes for his moves but he wouldn't really have any knockout blows. When sheathed, his normals, tilts and Smashes get ridiculous knock back but a bit more startup as he draws (and sheathes) his blade for every move. What's more, maybe they could go a little further and have it so that pressing B during certain timings could let him quickly switch between a drawn stance and a sheathed stance during his offense or maybe just during his other B specials. Give him a throwing star projectile that has explosive effects and a lightning based move and he's good to go.
