Hellboy is a 2004 supernatural action-thriller film directed by Guillermo del Toro. The film is based on the Dark Horse Comics work Hellboy: Seed of Destruction by Mike Mignola. It was produced by Revolution Studios, and distributed by Columbia Pictures.

In 1944, the German Nazis work with the undead Russian mystic Grigori Rasputin on an isolated island off the coast of Scotland to build a dimensional portal. They intend to use it, with Rasputin's help, to awaken the Ogdru Jahad, monstrous entities that have been imprisoned and asleep since an undisclosed time, to destroy their enemies. But Rasputin secretly intends to use the entities to bring about the destruction of the entire Earth. He is aided by his servant, Ilsa von Haupstein, to whom he has granted eternal life, and Nazi Lieutenant Colonel Karl Ruprecht Kroenen, Hitler's finest assassin and leader of the Thule Occult Society. The United States sends a small Army team to destroy the portal, guided by a young doctor, Professor Trevor Broom, who is well-versed in the occult. In the ensuing battle, the German scientists and soldiers are killed and the portal is destroyed, in the process absorbing and apparently killing Rasputin. Ilsa and Kroenen escape capture. As the Army team surveys the ruins for anything that may have sneaked into their dimension through the portal, they discover an infant demon with a stone right hand. Broom coaxes it into his arms with a Baby Ruth candy bar. They name the little creature "Hellboy."

His adventures have also been captured in various media, including animated films, novels, comics, and a range of merchandise.
