Leeron Littner

Leeron Littner (リーロン・リットナー), or simply "Ron", is the village mechanic of Littner, who is able to repair and scavenge the various Gunmen 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, he helps to give information about both Gurren and Lagann, as well as the Gunmen the team finds in its travels.

Personality
Leeron is fairly flamboyant and openly, stereotypically gay. This often played as comic relief in the series, with Leeron often taking his campness to ridiculous levels just for the sake of freaking people out. Despite this, Leeron is a very rational person and more than capable of being serious when he has 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 he knew he would make a comeback the entire time.

Description
Leeron possesses an extraordinary aptitude for both technology and mechanics and is in charge of maintaining team Dai-Gurren's Gunmen. Much like Rossiu, Leeron seems to have a keen sense for trouble and is often prepared for the misfortunes that befall his team. Unlike the Groove King, Leeron has total faith in Dai-Gurren team to claim victory in their battles. Leeron never joins the fight, except for the battle against the Anti-Grooves. He usually stands clear of the fighting while providing tactical support to the Gunmen pilots through their communications systems.

Powers and Abilities
Despite not specializing in combat or fighting ability, Leeron is lauded for his intelligence and creativity and is vaunted as the most intelligent human in the series by Lordgenome himself. His genius allows him to create and modify vast machinery into a variety of forms and explain the abstract phenomenon that occurs in the Gurren Lagann Universe. He's 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 himself, the human race owes their intelligence and aptitude to their own Groove Power considering with the span of seven years he went from being dysgraphic and illiterate to programming interstellar machines.

Trivia
