Notice the land octopus is the one who looks scared here, and I don't blame him. If I saw that psycho running around with a shotgun and butcher's knife, I'd be trying to shield myself too. The last time I saw a guy looking like that he was trying to kill Reid Fleming.
I actually had bought this comic as a kid. I think you can probably guess why. It wasn't as exciting as the painted cover promised, but then, it was a Gold Key comic. I'd love to have that original painting, though.
