Rihanna shows off masculine side in an international character poster for "Battleship". Portraying a tough Petty Officer Raikes, the Bajan singer is devoid of her signature fashionable look. She is seen holding a machine gun while sporting a tattoo on her arm and having dirt on her face.

Aside from RiRi's one-sheet, Universal Pictures revealed posters for Alexander Skarsgard's Stone Hopper, Liam Neeson's Admiral Shane and Taylor Kitsch's Lt. Alex Hopper, each in their naval uniforms. There is additionally a poster of a robotic alien, which is the major enemy in the sci-fi movie.

Back in September 2011, Rihanna discussed her heroine character in "Battleship". She told ET Online that Raikes is a "badass weapons officer; she knows everything about weapons, not only hers, but all the weapons on board."

The "We Found Love" hitmaker went on explaining her weapon specialist character, "It really got me into the emotion of the character. She's a fighter. She's a killer. She's not afraid of anything. She likes a challenge because she can handle it."

The anticipated action movie centers on an epic action-adventure that unfolds across the seas, in the skies and over land as the Earth fights for survival against a superior force. It follows an international naval fleet at Pearl Harbor which engage in an intense battle against an alien race known as "The Refents".

Based on Hasbro's classic naval combat game, "Battleship" is directed by Peter Berg with Erich Hoeber and Jon Hoeber writing the screenplay. Also supporting the movie are Brooklyn Decker and Hamish Linklater. Universal has set a May 18 U.S. release date for the film.
