Simon (Gurren Lagann)/Bio & Battles

Simon was born in Jeeha Village, one of many subterranean civilizations on Earth in the far future, and orphaned at the age of seven as he saw his parents getting crushed before his eyes during an earthquake. The incident traumatized him and gave him a harsh phobia for earthquakes. He eventually befriended the local gang leader, Kamina who eventually recruited Simon into his gang called Team Gurren. The two became so close that they started to call each other brother.

One day, Kamina was caught while he tried to escape to the surface and was jailed. While Simon was helping him break out Jeeha Village is attacked by a large mech while a girl with a gun, by the name of Yoko Littner comes in to stop it. Simon, Kamina, and Yoko, were able to defeat the mech with a smaller mech, Simon found earlier that day.

It was then revealed to Simon and Kamina that the surface world is being ruled by animal/human hybrids called Beastmen who pilot giant mechs called Gunmen. Deciding to free the surface world from the Beastmen, Kamina and Simon joined Yoko in her fight against the Beastmen.

Simon succeeded in overthrowing the Beastmen and their king Lordgenome at the cost of losing Kamina, but soon discovered their reason for ruling Earth and oppressing the human population. Would they develop any further, a being called the Anti-Spiral would come out to Earth and wipe it out in order to prevent a galaxy-wide apocalypse. With the aid of Team Dai-Gurren, Simon managed to defeat the Anti-Spiral and convinced they would be able to stop the apocalypse.
