Castlevania: The Bloodletting

In 1996 Konami was developing a Castlevania title for the Sega 32X, however the game was quickly canceled. It never had an official name, but it's working title became known as Castlevania: The Bloodletting. The only images that exist from the game are sprites for 3 of the main characters who were intended to be in it. Richter Belmont and Maria Renard, who were the heroes, and a Rival to them, who never received a name.

Shortly after the game's production was ceased, Castlevania: Symphony of the Night was announced for the Sony PlayStation. Several members of the team that were working on Bloodletting, joined the development team for Symphony of the Night. Hardly any info was ever revealed as to what the storyline would have been for Bloodletting, except for that the unnamed Rival character was to be Richter's main nemesis in the game. No screenshots of any gameplay were ever released.

Richter's sprite from Bloodletting became the Fake Trevor sprite in Symphony of the Night:

The Rival's sprite was transitioned into Richter's sprite in Symphony of the Night:
