15 days until Hellboy Day - James H. O'Donnell
One of the more mysterious wards of the B.P.R.D., J. H. O’Donnell easily seems to be just a crazy guy. Once a prodigy, now devoured by psychosis, O’Donnell still manages to be a valued member of the Bureau due to his vast knowledge, even if that knowledge is very difficult to access due to his condition.
James’s condition was brought upon during a failed mission with Hellboy. I say mission, however it really was just a trip to pick up some things. O'Donnell and Hellboy entered the mansion of a late necromancer in order to gather information from its library. Becoming separated, O'Donnell accidentally stumbled upon a secret library, where a ceremony of undead paranormal researchers from throughout time were gathered. While the events cannot really be explained, they somehow seem to have attacked him, rendering him psychotic. After Hellboy destroyed the house (there was a big monster, you know Hellboy stuff), he found O'Donnell wandering down the street aimlessly.
O'Donnell requires special support in order to live. As he cannot care for himself, he has a nurse that tends to him. He is still fully capable of reading and studying and is in fact one of the B.P.R.D.’s most important scientists. After his incident, he is even able to recite information from books that haven’t been seen by humans in 500 years. This knowledge is important; James has vast knowledge about the “Hems”, which gives the bureau a major edge during their invasion. Not an action hero, O’Donnell has few notable moments in the books, and mostly served as a portent of bad news, or a resource for understanding the current situation.
O'Donnell would die during the B.P.R.D.’s dash towards Cavendish hall during the apocalypse. Using himself as bait in order to buy the team time to get into the bunker, O'Donnell was a huge factor in why the team has survived this long.
