Hellboy: Blood and Iron is the second in the Hellboy Animated series (the first being Hellboy: Sword of Storms), written by Tad Stones and Mike Mignola. It first aired in March 2007 on Cartoon Network.
In 1939, young Professor Bruttenholm (affectionately nicknamed "Broom" by his colleagues and students) destroyed Erzsebet Ondrushko, a vampiress who bathed in the blood of innocents to stay young after selling her soul to the Queen of Witches, the goddess Hecate. Years later, a haunting at upstate New York is brought to the BPRD's attention. The elderly Professor Bruttenholm decides to investigate it himself, taking top BPRD agents, Hellboy, Liz Sherman and Abe Sapien, who are more worried about his welfare than a haunting.
Much to Broom's horror, it turns out that the ghosts are the victims of Erzsebet Ondrushko, who is soon resurrected by her two harpy/hag servants. While the others deal with her minions and Broom settles his affairs with Erzsebet once and for all, Hellboy ends up battling Hecate herself, who has been watching him for some time and desires him to embrace his true destiny: one that includes the destruction of mankind.
