MMA stars show off Halloween spirit, Dominick Cruz wins best costume

Dominick Cruz couldn't just be a zombie or a vampire for Halloween. He had to make his costume personal (and hilarious).

Decked out in Muay Thai shorts, a floppy blonde wig, a black eye and - the best accessory of all - a jar of peanut butter, Cruz fired shots at UFC bantamweight champion T.J. Dillashaw and his mentor and coach Duane "Bang" Ludwig.

Both men recently departed Sacramento's Team Alpha Male for greener pastures at Colorado's Elevation Fight Team, and with a title shot against Dillashaw looming on Jan. 17, Cruz decided now would be a good time to heat things up a bit.

Check out Cruz's get-up and others from fighters such as Paige VanZant, Joe Lauzon, Daniel Cormier, Miesha Tate, Felice Herrig and more below:
