    Comics History

    A German scientist working for the Nazis, and a member of the Thule Society, Dr. Kroenen became one of the top scientists for Project Ragna Rok, and a close disciple of Grigori Rasputin, along with Ilsa Haupstein and Leopold Kurtz. He was present with Rasputin at the secret ritual in Scotland that brought Hellboy to the world.

    Kroenen, Haupstein, and Kurtz were frozen inside a secret Nazi base, until they were resuscitated by industrialist Roderick Zinco, acting on Rasputin's orders. Kroenen resumed work on several of his former projects, including making an "Apocalypse Army" by combining corpses with robotics. He also convinced Zinco to retrieve the head of his colleague, Herman von Klempt, from South America. Kroenen retained an affection for his colleague, though Rasputin had rejected von Klempt as unsuitable for Ragna Rok. When von Klempt's head was re-animated, he tried to convince Kroenen to abandon Rasputin's plan - to awaken the Ogdru Jahad - and instead to use the Army to retrieve von Klempt's work in South America. Overhearing, Kurtz became furious and attacked von Klempt's head, screaming, "Rasputin is master!" In a panic, Kroenen seized a knife and killed Kurtz. When their plan failed, an enraged Rasputin struck Zinco blind. Wandering around, Zinco accidentally pressed a self-destruct button in the base, destroying it completely and taking Kroenen with it.
