I know that HolyCarp mentioned this already, but I'll expand on it. When a character is killed by Leixia's CH 6BA, they say something different for their deathscream (different from when killed by Yoshi's CE) Here are some I remember. Elysium: Incomprehensible.. Leixia:Mother... Tira: All broken... Viola: How.... Pleading (?) The announcer cuts Viola so I can't hear what she says. I think it's really cool how PS gave every character at least 3 different death cries. Now only if they were used random instead of situational....
Viola says a bunch of different stuff when she gets ORB backgrab depending on the character. Such as... Fall.. Star of Chaos/Full moon/New moon/Crimson moon and so on.
Viola can JG an orb GI.
Taki is somewhere in America (?) looking for Toki which is when she goes missing.
When you customize a character with Viola's hood, you can't even see her hair drills unlike in her default 1P.
