This is Godzilla vs. Heisenberg, a Godzilla and Breaking Bad mashup mashed together by AwesomenessX (who also made last week's Guardians of the Galaxy/Parks and Rec mashup). Mashups -- that's an unusual hobby to have. Like licking bus seats, but with a little more potential for a Youtube revenue stream.
Keep going for the video.
Thanks to Hoffmanberg and Dustyn, who could both bare-knuckle box Godzilla to death if they wanted and may or may not be secret biological weapons developed by the Pentagon.
