9. Rulk
The Red Hulk (Rulk?) has been described by many comic book fans as one of Marvel's stupidest creations, and it's not hard to see why. Though there was some initial excitement surrounding his identity, that quickly evaporated when it was revealed that this murderous Red Hulk was in fact General Ross, Betty's father and the man who had spent most of his life trying to take Bruce Banner's Hulk down. It all ended up being a nonsensical mess. And no, where his moustache goes when he transforms was never explained. This led to a number of longtime Hulk supporting characters Hulking out, including Betty Ross and Rick Jones. A lot of what makes the Green Goliath special faded away as a result, but it might not actually be all that surprising for Marvel to turn to the Red Hulk for inspiration when they eventually make another Hulk movie. After all, these Hulks do star in their own successful animated series, so being in a movie might not be a huge leap.
