The Super Namek derives from the fusion of a Hyper Namek and another Namek of equal power. This immense combination of power results in little to no physical appearances. The only real difference is the level of strength. In the past several Nameks found the secret "ancient knowledge" to becoming Super Nameks. The power went to their heads and they became violent and tyrannic. The peaceful Nameks banished the Super Nameks from the planet using the magic of the Dragonballs.
