The Xorda are a warlike alien species from the planet Xorda. They are somehow capable of intergalactic travel despite residing in an aquatic environment. In the 21st century of Earth, their emissary came to offer an alliance with the humans, but was captured and dissected by Dr. Ivan Kintobor and his science team. Enraged, the Xorda attacked Earth using Gene Bomb weaponry. They then left Earth, thinking they had killed all human life, when in reality the surviving creatures attained human DNA and evolved into what are now known as Mobians, and Earth was renamed Mobius by the new inhabitants.
