Regent (Battleship)

The aliens (called "The Retards") from the 2012 Movie Battleship are a race of sapient, spacefaring species.

Biological Appearance
The Retards are a tall mammalian species that appear humanoid. They were bipedal and wore dark armor with bronze-gold highlights on top of a skintight suit. They had four fingers on each hand, miniscule ears, flat faces, a strange porcupine-like bristle on their chin and green spectral eyes that are extremely sensitive to exposure of sunlight. They also had two extra nostrils underneath their eyes.

To add with their armored uniform, they had oxygen helmets that was equipped with an unknown gas and an identification friend or foe system that can detect enemies through red-green vision. The helmets also had extreme-sunglasses lenses to aid with seeing in the sunlight.

History
The Retards were a species that lived in an unidentified homeland much like Earth, to which humans named it "Planet-G", to which they spent most of their lives raiding other planets before destroying them. In 2005, the planet was discovered and the humans sent a message, to which no reply came through. 7 years later, in 2012, the aliens respond by flying to Earth in five ships, one crashing in Hong Kong.

Upon landing in the Pacific, the Retard mother-ship created a force-field that blocked all naval ships from entering (other than the American and Japanese navy battleships) and covered all of Hawaii. After the ships attack the three assault ships, they shoot cannons that explode upon contact with their enemies, destroying the USS John Paul Jones, the USS Sampson and the Myōkō; a Japanese missile destroyer.

The Retards then attacked Hawaii with strange machines called "Shredders" that tore through a military base, highway roads, buildings and nearly killed a boy playing baseball. The aliens then go to Oahu and use the satellite communications to send messages to their homeland.

However, upon using the gigantic and retired warship "USS Missouri", they sidetracked the alien ships and destroy all, including the mothership. They also send a warhead that destroys the aliens in the Oahu observatory.

Apparently, it is believed that they may have survived or have returned to Earth, as in a post-credits scene, schoolboys and a handyman in Scotland discover a strange object. Apparently excited to see inside, the handyman manages to open the ship, but before they can look inside, one of the Retards' hand appears, making the boys and handyman to run screaming.
