In a 1994 interview with the game's planner Junichi Ohno & Capcom producer Noritaka Funamizu published in Gamest magazine, they stated that they considered putting monsters from all regions in the series. From the beginning, there were lots of yōkai (traditional Japanese monsters), but they cut the number of them down due to the team realizing that most international players would not recognize them.

Some "weird" characters from the beginning of Darkstalkers: The Night Warriors' development that were rejected include:
•An old man who was dressed head-to-toe in a salaryman’s suit.
•A nurikabe yōkai that could not move and was always in a guard state, which the game's planners mentioned would be easy to finish due to there being little about the character to animate.
•An Invisible Man where the only thing about it the player would be able to see was his floating gloves, which was done so the development team could draw fewer graphics.
