I recently showed the trailer for X-Men Origins: Wolverine to my wife, and was explaining the different characters that seemed to be shown in it. Most obvious to me (besides Gambit and Sabretooth) was the big fat guy, that I assume is the Blob. I described him as being the opposite of Juggernaut; once he sets himself down, he can't be moved. He's also super-strong and his fat makes him really soft so it absorbs bullets and punches, so you can't hurt him. My wife pointed out that he has a bunch of powers, which is odd when you think about it. It finally occurred to me that the Blob really only has one power; he's super-fat. All his powers are super humanly enhanced stereotypes of fat people; being really heavy so you can't move him, being really soft and rubbery, even having his own gravitational pull. Kind of offensive when you think about it.
UPDATE: I had a tasteless joke at the end, but I've deleted it.
