Brauner is the main antagonist in Castlevania: Portrait of Ruin. In his past life, he was an artist prior to his vampirism. He is the one who created the many portraits which the player must travel through to get to different areas.
An elder vampire with a resemblance to Count Orlok, Brauner recreated Dracula's Castle using the souls of the dead from World War II in order to destroy humanity. Unlike most other vampires in the series, he has no loyalty to Dracula due to his repeated failures in the past. Brauner disdains humanity because his two real daughters were killed 30 years ago, during World War I, and he has deluded the vampiric Stella and Loretta into believing that they are his daughters. After the player defeats him in battle, Death comes in and finishes him off, saying his presence is what kept Dracula sealed.
And he is reprised by Jamieson Price in the English dub and Hisao Egawa in the Japanese dub.
