Richter first appeared in Rondo of Blood (and Castlevania: Dracula X as an alternate retelling). He has to fight Dracula who has just been resurrected. Along the way, he saves his girlfriend, Annette, and the villagers, Maria Renard, Tera and Iris.
He appears as a secret boss in Castlevania: Portrait of Ruin. He only is a memory of the Vampire Killer but, when he is defeated, the whip is stronger. He is also a playable character in the Alternate mode.
