The Kree Empire

The Kree Empire is one of the oldest and most powerful races of the galaxy.

The Kree are ruled by the Supreme Intelligence, and their culture is based on the supremecy of science and technology.

The Kree have been locked into a war with the Skrull Empire for centuries.  When the Kree identify a planet they desire, they dispatch a Kree Sentry robot, which "pacifies" the native race on the planet.  If the planet's inhabitants are advanced enough to defeat the Sentry, the Sentry robot detonates the Nega-Bomb it carries within its form, which will kill everyone on the planet, making it suitable for Kree habitation.
