Algon is one of the first Element Men created by Ra.
Hoping to escape the Kingdom of Elements, Algon uses the Orb of Ra to begin terraforming the Earth and replace himself with Rex Mason so he can leave. The Terrifics chase after Rex and find themselves in separate parts of the Kingdom of Elements, but regroup and manage to trap Algon in their with the orb.
As an element man, Algon's body is made of every element in the periodic table. He is capable of shapeshifting into whatever element he desires, as well as stretching great distances at ease. Because of how much older he is than Rex, he is implied to be much more skilled and knowledgable at being an Element Man.
