UFC bantamweight champion Ronda Rousey is one of the many stars in Sylvester Stallone's 'The Expendables 3,' which is her first role in a major motion picture, and she portrays one of the toughest female characters ever seen on the big-screen.

It is no surprise that the 2008 Olympic bronze medallist in judo suits her character very well, but this undoubtedly doesn't follow the usual stereotypical female characters cinemagoers have seen in the past. Rousey is getting tired of this, especially in comic-book movies.

"I'm tired of watching this thing where the woman's superpower is dumbed down," she recently said to USA Today. "In 'The Fantastic Four,' the woman is the invisible one. In 'X-Men, [telekinetic] Jean Grey gets tired all the time. Wonder Woman is cool, but she has bulletproof bracelets, while Superman is a bulletproof dude. It's like she has really cool accessories. I think about that a lot."

Rousey also successfully combined sexiness with toughness in the action-packed flick, but this was a hard feat to accomplish and she ran into a bit of trouble along the way. While shooting her first fight scene, wearing a figure-hugging red dress and 6-inch stiletto heels, the 27 year-old athlete chose not to change into some more suitable attire, and as she went to hit a beer bottle of a guy's head, her heel snapped.

"It was broken, unsalvageable," Rousey recalled. "Someone had to go out and buy shorter heels to do the scene."

The MMA fighter also told USA Today that she does like getting all dressed up and looking glamorous, but it isn't something she would want to do every day.

"I try not to look my best every day," Rousey said. "If you are designered up every day, you cannot step it up. I'm all about flipping switches. I can go from jock to red carpet. It takes a little more to get glamorous than it does to get into killer mode. But I like to have that ace to pull out."
