In a 1998 interview with the game's general producer Noritaka Funamizu published in Sega Saturn Magazine, he stated that the woman who designed Victor von Gerdenheim had a thing for butts, which lead her to make more butt moves for Victor.
According to former Capcom artist Katsuya Akitomo, Q-Bee's design is a ripoff of Chika, a character from Yoshitoh Asari's manga Space Family Carlvinson. Like Q-Bee, Chika was fully an insect, and only imitated humans through mimicry and by wearing a disguise. Katsuya Akimoto made the original character creppier and removed the original comedic parts.
According to general producer Noritaka Funamizu in a 1997 Gamest magazine interview, he was asked why the rounds mechanic was removed in the game? He responded:
"The structure of the rounds is one element of fighting games that’s hard to change, but for this game, we didn’t want the flow of the fights interrupted. The Damage Gauge System was originally part of a different game’s system. We tried inserting it here and it turned out to be really interesting, so we kept it."
According to general producer Noritaka Funamizu in a 1997 Gamest magazine interview, he was asked why he wanted to make Darkstalkers 3 just two years after Night Warriors: Darkstalkers' Revenge was released? He responded:
"Well, we’d been planning to make a sequel since we finished Revenge. But there was a feeling we had of wanting to re-evaluate, from zero, the very concept of what it means to be a “monster.” We have a guy on our team who we call the “one many army”, who does planning work, and he handed us the initial game plans for Vampire Savior. From there we officially formed a team and got down to work. But the setting and story came first, in those plans."
According to general producer Noritaka Funamizu in a 1997 Gamest magazine interview, he stated that the original plan for the Dark Force system was to make it so that "you could just completely pummel your opponent" while in Dark Force. However, there were problems with the idea, so it morphed into the form that was used in the final game, having been developed with an emphasis to making Dark Force feel unique to each fighter in the game.
According to general producer Noritaka Funamizu in the Gamest magazine interview, he named the third game for Japan “Vampire Savior” because he wanted each title to have a unique name instead of just calling it by it's early name 'Vampire 3'. He added "As for the meaning, I’ll leave that for players to discover."
