Hellboy - World's Greatest Paranormal Detective (SDCC)

Originally published in black and white in 1993, as a part of San Diego Comic Con. Reprinted in color in Hellboy Vol. 1: Seed of Destruction.

Synopsis
Hellboy investigates an abandoned town in 1952. Stumbling upon a lone dog, the dog grows into a hulking beast, who Hellboy identifies as the god Anubis. After getting pummeled by the beast, Hellboy hits a rickity sign-post, and the large arrow mounted on top falls, striking Anubis in the head. The beast falls backward onto an old gas pump, causing it to explode. Anubis is destroyed as Hellboy is blown back from the explosion.
