No doubt Dwayne "The Rock" Johnson has the biggest muscles in Hollywood. However, there's a new threat to the throne!
Oddly enough, the guy who's giving The Rock a run for his money is actually a cat! And the dude is ripped! At first it looks like some sort of computer animated special effects, but then he comes closer to show off his bulging shoulders!
Ok, we wouldn't wanna cross this cat in a dark alley.
