The Spartan soldier, Aeon Calcos, like Sophitia, was one of the twenty-four warriors to receive an oracle from the god Hephaestus to destroy Soul Edge–one for every letter of the Greek alphabet. Armed with the holy Xi Sword and Game Shield forged for him, he set off on his journey. However, he became lost in a vast desert and eventually collapsed. A group of kindly desert travelers rescued a dehydrated Aeon and brought him to their village, and he was about to repay them by teaching them swordplay. He was unable to exchange their kindness, however, as the Evil Seed rained down and temporarily changed Aeon into a mindless killer, causing him to slaughter everyone in the village.
Kunpaetku, the grand priest of the cult order Fygul Cestemus, eventually heard stories of him and captured Calcos so that he may be used as a human guinea pig in a diabolical experiment, causing him to transform into a lizard the first of many lizardmen to come. Calcos was ordered to bring Rock's adopted son, Bangoo, so that his soul could be stolen. The creature was eventually tracked down and defeated by Rock for the kidnapping, while aiding Astaroth in pursuing Soul Edge.

Both had their own feats and defeat in their past with Aeon defeated by Rock and Riptor defeated by TJ Combo in Killer Instinct. However while Aeon grow more primal and deadly on his own, Riptor have been upgraded to be more dangerous by the Ultratech, Allowing her to be more smarter then Aeon and give her the bigger advantage.
