A normal eel, Eelar was mutated into a humanoid creature after exposure to the radiation from a Badoon Mento-Programmer that implanted the Badoon's mission of conquest over the planet Earth. The creature would battle both the Defenders and the 31st Century Guardians of the Galaxy who had traveled back to the modern area at that time. With the truth regarding Eelar's mutation realized upon the discovery of the Mento-Programmer, the combined efforts of both the Guardians' Vance Astro and the Defenders' Dr. Strange, Eelar was restored to a normal eel, never to menace mankind again.
