Moving on from the Direct for a second, I know folks keep talking about Sliding Slinger, but I'm imagining Ghost Factory being an interesting/outright scary move. I imagine it being like a counter of sorts that makes Elma invincible (but maybe immobile) for a split second or so (think Obito from Naruto). If it's slightly longer than that and/or she can move around, maybe give the move a cool down period or something. IDK, but I just think Ghost Factory is her coolest attack lol.
Elma seems like a rushdown character that excels at mid range but would probably be really light to compensate (and if they go by the gravity in X, she probably is floaty in the air and jumps pretty high). They can give her a stealthy attack in the fashion of Greninja, since she has an art that allows you to briefly go undetected. Shadowstrike can work like Backslash, that is, it does more damage if you attack the enemy from behind.
Has anyone suggested if weapon switch might work depending on if smash attacks are charged or not? That is, uncharged is short range and charged is long range. I like the idea of her tilts being swords and smashes being guns or vice versa, with the special button attacks assigned to her signature arts. Actually dedicating a button to switch may work, too. I've seen that suggestion probably more than the others. Regardless, I hope she uses the swords/guns roughly equally.
If Elma gained "TP" mid-fight like Cloud gained Limit, that'd be nuts. Imagine going overdrive after meeting certain conditions.
