The Prawns from the 2009 film, District 9, are an invasive and aggressive alien species colonizing on the planet Earth.
After arriving, the alien species are quarantined to a small district in Johannesburg.
Their population quickly expands, in part due to their asexual reproduction, and they become a danger to the surrounding human population.
The Prawns are stronger and taller than humans with a hard exoskeleton. They are also skilled weaponry engineers and create a range of extremely powerful energy weapons that can only be activated by their species.
