I was bored, so I made this. I hope you get a kick out of it.
Darkstalkers in a nutshell:
Demitri: This was supposed to be MY franchise. I was supposed to be the protagonist.
Morrigan: Not anymore. I guess the fans love me more, Demitri.
Demitri: But wait. Capcom has never officially declared the TRUE protagonist of the Darkstalkers series, and, unfortunately, I don’t think they’ll be making a new game anytime soon…
Morrigan: Yeah, that's a shame…but I’m in crossovers, and my theme is catchy.
Demitri: Well, so is MY theme.
Morrigan: It is pretty catchy, I’ll give you that, but I think my theme is a bit more memorable. And besides, your Midnight Bliss is a little…questionable sometimes.
Demitri: But it’s one of my most iconic moves!
Morrigan: Remember when Capcom wanted to get you into the MVC series as a character?
Demitri: Yes, but Marvel didn’t want their characters to be hit by Midnight Bliss, even though Capcom insisted on including me and that move.
Demitri: But still, they let a succubus, a half-naked cat lady, and a jiangshi in MVC3, but not ME, a VAMPIRE, which is the name of the Darkstalkers series in Japan?!
Morrigan: Yep. Pretty much.
Demitri: I hate you so much…
Morrigan: Love you too, Demitri.
Morrigan: Just be glad you weren’t in MVCI. That game didn’t do as well as we would’ve hoped, and it had me and Jedah in it.
Demitri: I hate that delusional want-to-be vampire even more…
Morrigan: So do I. He’s crazy.
-Kellen Goff as John Talbain. Dude can nail that bestial feel in one's voice, if you've heard his performance as the Father Spider Demon in Demon Slayer.
-Erica Lindbeck as Morrigan. If you've heard her as Jessie in FF7R, you know she could pull off the flirty voice. She could also pull off a mature voice from her performance as Saber of Red in Fate/Apocrypha.
-Keith Silverstein as Dimitri Maximoff. Keith definitely has that sort of charisma in his voice. Zhongli in Genshin Impact, En in Dorohedoro, he has that sort of deep baritone and silky smooth voice that could definitely fit Dimitri.
-Ray Chase as Jedah Dohma. His voice is great. When I think about Jedah Dohma and how he could sound, I imagine an evil Bucciarati, or Lancer of Black if he played up the sinister.
These are the four that stand out on the top of my head.
