To start I’m keeping the most of voices of Shantae and her friends the same as of Seven Sirens, (though I may recast Sky for…reasons) Risky on the other hand, mainly because it’d be a lot more work for Cristina to fully voice the main hero AND villain in a potential animated series. As for who I’d like to see play Risky, my top picks at the moment are
Rena Strober (same English VA for Azura from Fire Emblem Fates BTW) or
Laura Post
-After hearing Ira Gamagoori's English voice from Kill la Kill, I cannot hear anyone else other than Patrick Seitz for Ammo Baron. His hammy yet militaristic sounding voice I feel is perfect for this guy.
-Maybe Griffin Puatu for Squid Baron (Spitz from WarioWare Gold)
-For Techno Baron, I'm thinking maybe Kirk Thornton, his Frog-Man voice from One Punch Man, albeit brief, sounds like it'd work, though Matt Mercer with his
Victor voice from Critical Role could also work. Just someone that sounds raspy and small
-Maybe it's because he looks so much like a Dungeon Master but I could totally see Matt Mercer or Kaiji Tang (with his
Kurogane voice from Tales of Berseria) as Hypno Baron.
-I definitely think Christopher Corey Smith would work for Abner after hearing his voice for
Albus from Skullgirls.
-Poe I’m thinking Sungwon Cho along the lines of his Express Owls voice from A Hat in Time
-As much as it is type-casting, I definitely want to see Twitch voiced by Sarah Williams (
Jinx- League of Legends, Nonon Jakuzure-Kill la Kill)
Vinegar I'm having a little trouble with but I'm leaning towards Carrie Keranen. (Initially I went the same route as you picking just one voice actress, the one I had in mind was Stephanie Komure aka Patricia Wagon)
-I’m still unsure about who I want for Mayor Scuttlebutt, but two actors I could see are either Chris Cason or Edward Bosco (something like his 18-Volt voice from Warioware Gold) Trying to think of a character or actor with a doofy sounding voice
-for the Chef Girl, considering how well she’s able to handle long-winded nonsensical rants if her Mako voice from Kill la Kill is any indication, I think Christine Marie Cabanos would be perfect for the role (though the exact voice she could use would be more like her Delthea voice from Fire Emblem Echoes)
-and for miss Holly Lingerbean, I dunno what it is, but something about this character just screams Kira Buckland to me, specifically her Hydra Bell voice from Blood Lad
