Since Capcom isn’t bringing Darkstalkers back, perhaps character concepts from that can go into KI.
Except Sabrewulf was made before Jon Talbain. Lord Raptor is a zombie but Spinal is an undead skeleton.
As for the others…
Kan-Ra: Anakaris
HIsako: Bishamon & Hsien-Ko
Fulgore: Huitzil
Cinder: Pyron
If there were other Darkstalker-like characters…
- Felicia - Catwoman
- Demitri & Donovan (except he’s a half-breed) - Vampire
- Morrigan & Lilith - Succubus
- Victor - Frankenstein
- Rikuo - Merfolk
- Sasquatch - Cryptid
- B.B. Hood - Hunter
- Q-Bee - Insect
- Jedah Dohma - Demon (but a “grim reaper”)
