Well considering Hellboy ages much slower than humans, one has to ask, how far in the future is this set? If not that far then, how are they "Hell Seed"? Is their mother human? I hope to God the studio doesn't make them stupid fly by wire martial artists with ridiculous super speed abilities. What made Hellboy a hit for me was the fact that his super power, besides strength and toughness, was his crusty, gritty attitude.
