Leeron Littner

Leeron Littner (リーロン・リットナー, Rīron Rittonā?), or simply "Ron", is the village mechanic of Littner, who is able to repair and scavenge the various Gunmen he and his group encounter. Leeron first helps Simon with repairs to Lagann. When Kamina, Yoko, and Simon go off to fight the Beastmen, Leeron offers to go to help with repairs. Along the way, he helps give information about both Gurren and Lagann. Leeron explains about how they can combine when they first do so to fight viral.

Seven years later, Leeron is put in charge of the technology division. He is the only one to show no signs of aging and is never really referred to as an "old timer". Leeron helps in creating the spiral guns to destroy the Mugans and gave support to Rossiu. Leeron creates the digital simulation of what would happen if the moon crashed into the earth and joined the group in going into battle with the Anti-Spirals. Leeron simplifies numerous things for Kittan and the others when explaining their situation and works with the Spiral king in figuring out the ways to counter the attacks. Leeron seems to know almost everything that others don't, similar to how Rossiu is, and is troubled when Kittan dies. Unlike the Spiral king, Leeron had total faith in the Dai-Gurren team to win. Leeron never goes into battle, but usually stands behind and gives moral and informative support.
