The sprite rips on the Night Warriors: Darkstalkers' Revenge page seem to be from Vampire Savior 2/Vampire Hunter 2, which is a different game(s). The game icon is actually from Night Warriors: Darkstalkers' Revenge, but the page URL also seems to refer to Vampire Savior 2. The naming in the Darkstalkers series is kind of inconsistent and confusing, so it's understandable that issues like this come up. For reference:
Darkstalkers: The Night Warriors (INT) / Vampire: The Night Warriors (JPN) - First game in the series.
Night Warriors: Darkstalkers' Revenge (INT) / Vampire Hunter: Darkstalkers' Revenge (JPN) - Second game in the series. The game the page in question appears to be about
Vampire Savior: The Lord of Vampire (JPN, INT arcade) / Darkstalkers 3 (INT Playstation) - Third game in the series
Vampire Savior 2: The Lord of Vampire & Vampire Hunter 2: Darkstalkers' Revenge - Upgrade version(s) of the third game in the series, sort of a Pokemon Red/Blue type deal where they're the same game but the roster is split across the two versions. This is the game(s) the sprites on the page in question are from.
Darkstalkers: The Night Warriors (INT) / Vampire: The Night Warriors (JPN) - First game in the series.
