vulnerable form. It was once believed that Johann was vulnerable to psychic attack and his ectoplasm could be taken over by stronger spirits, but it was discovered that he is immune to possession and can take dominance over malevolent spirits - even an Ogdru Hem. The only protection Johann has from dissipation is his B.P.R.D.-built containment suit; once the suit is breached, he must find a new container for his essence or he will cease to exist. In other media Johann Kraus appeared in the 2008 film Hellboy II: The Golden Army. In the film his name is spelled "Johann Krauss". His character's movements were supplied by British actors John Alexander and James Dodd, and his voice was performed by Seth MacFarlane. Thomas Kretschmann was previously cast for the voice, but was replaced. Krauss is head of the B.P.R.D.'s Ectoplasmic Research division in Washington, D.C., and is sent to the Bureau's headquarters to take command of the team, after Hellboy embarrasses the Bureau and the government by revealing himself to the public. The cause of his condition is not explained, but he hints that it was connected with the loss of the woman he loved - a fiancée or a wife, whose ring he still carries around with him. He said that his containment suit was designed by the B.P.R.D.'s former head, Trevor Bruttenholm. According to the film commentary, Guillermo del Toro stated that, in the planned story for the third Hellboy film, Krauss would also have some history with the character of Nazi scientist Karl Ruprecht Kroenen. Krauss immediately strikes Abe Sapien and Tom Manning as knowledgeable and efficient, while Hellboy dislikes him, possibly because he feels overshadowed, and as Hellboy himself says, Johann's name "sounds German... I don't like Germans", due to his hatred of Nazis. Krauss is punctilious, strait-laced, and scrupulously "by-the-book". In the commentary, Guillermo del Toro said that he used the character to express his idea of the perfect bureaucrat: lacking a face, body, or any individual identity. This is a departure from the comics version, where Krauss is portrayed as quite compassionate and feeling, often playing an avuncular role towards the rest of the team. Both the comic and film version of Johann can leave their containment suit at will, though it is uncertain how long he can do so without dissipating; once freed from his suit, his ectoplasmic form can physically manipulate objects
