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 they and their 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, they help give information about both Gurren and Lagann, as well as the various Beastmen they encounter.

Personality
Leeron is an androgynous non-binary character, describing themself as "neither a man nor a woman" in their original appearance. While the English dub portrays them as a flamboyant gay man, there is nothing in the original script to validate that depiction. However, they are openly fond of both of the male protagonists, occasionally teasing them with come-ons and typically acting very affectionate towards them. While they are a generally playful person, Leeron is very rational and more than capable of being serious when they have to be.

Leeron is also one of the most loyal members of Team Dai-Gurren, being the only adult member of the team (other than Kamina) to never doubt Simon; while the majority of the team seemed completely shocked by Simon's recovery after Kamina's death, Leeron was simply smiling as though they knew he would make a comeback the entire time.

Description
Leeron is in charge of the technology division of team Dai-Gurren. They are 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 Muganns and gives support to Rossiu. Leeron creates the digital simulation of what would happen if the moon crashed into the earth and joins 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 has total faith in the Dai-Gurren team to win. Leeron never goes into battle, exept when they and the rest of Team Dai-Gurren fought the Anti-Spirals in Tengen Toppa Gurren Lagann. They usually stand behind and give moral and informative support.

Powers and Abilities
Despite not specializing in combat or fighting ability, Leeron is lauded for their intelligence and creativity and is vaunted as the most intelligent human in the series by Sans Lordgenome himself. Their genius allowed them to create and modify vast machinery into a variety of forms and explain the abstract phenomenon that occurs in the Gurren Lagann Universe. They are noted for being the one who educates the rest of the cast on peculiar happenings and has been responsible for the many scientific breakthroughs that have been yielded by Team Dai-Gurren. According to Leeron themself, they owe their intelligence and aptitude to their own Spiral Power considering with the span of seven years they went from being dysgraphic and illiterate (being unable to read or write) to programming interstellar machines.

Trivia
