Did You Know?
In the comics, Dr. Walter Langkowski was trying to unlock the power of the Hulk with gamma rays. However, the gamma rays did not directly mutate his cells; rather, the gamma energy breached an inter-dimensional barrier, and allowed Langkowski to channel a mystical being called Sasquatch (which explains why he's the only gamma-irradiated being who isn't green). Of course, Langkowski thought that it was due to the gamma for a long time. See more
You've got a lot of nerve, Langkowski!
I've more than that, Bruce.
