Ergog

Ergog is the ancient Cavesaiyan ancestor of which makes him the direct ancestor of Ethan since he is cloned from Elcidman.

About
Ergog was the leader of a tribe of Saiyans on prehistoric (long before Planet Plant was colonized as Planet Vegeta). He lived millions of years before Frieza destroyed Planet Vegeta. He was the younger brother of Kuzog and had 32 other siblings. This makes Ethan and very, very distant cousins.

Power
He was not very strong, only being able to go Great Ape, like most people of his time period. Though he was just a simple tribe leader, his power level was higher than Nappa during the Saiyan Saga. He usually fought with a spiked club in battle but he also used his fists and fired ki blasts.

Death
He and his people fought against an enemy tribe who were invading his village and during the battle, Ergog went Great Ape and caused the enemies to flee. In the end, only the Enemy King was brave enough to fight and he cut off Ergog's tail which caused him to go back to base form. He then killed the weakened Ergog and took his tail back to his tribespeople as a trophy. The skeleton of Ergog was found by some of Frieza's soldiers millions of years later, on the deserted Planet Saiyan. His skeleton was put in a space museum funded by Frieza.
