I think a lot of people don't know the Hellboy animated movies even exist. There is Hellboy: Sword of Storms and Hellboy: Blood and Iron. Both feature the voices of the actors from the original live action movies by director Guillermo del Toro. They were released direct to video in 2006 and had the potential to become a full scale animated series. Unfortunately that never happened.

I wish they made a full TV series out of this
