The Nagmas are a sapient, spacefaring alien species who visited Earth in the year 50 BC, when they were in the middle of a war against the Tadsylwiens. Physically, they resemble tall, yellow-skinned humanoids, and usually wear golden armor. They hail from a planet called Gmana.
While the Tadsylwiens fight with their armies of Superclones, the Nagmas prefer to create armies of deadly robots.

- Just as the Tadsylwiens serve as a parody of American comics, the Nagmas serve as a parody of Japanese comics, better known as manga (which Nagma is an anagram of).
