I feel like I'm going crazy here. Very possible I dreamed this or something. I remember reading somewhere that there was an alternate version of Bruce Banner's backstory of child abuse, one that got significantly darker than the ones that were released, which went unused by Marvel. As such, the writer ended up editing the work and making an original graphic novel about it. Iirc, the Bruce analogue is always drawn as a giant, Hulk-like monster. I think the title might be something similar to "Monster", and that it was possibly in black and white, but I'm unsure.
Has anyone heard of this comic?
