Tetsukan Littner

Tetsukan Littner is a member of the control team for Dai-Gurren. He is in charge of monitoring the condition of the ship. After the timeskip, he becomes a part of Leeron's science team. Also due to being attracted to the fast-food restaurants that were built in the new city he became obese. In the "alternate universe" scenes in Episode 26, Tetsukan is seen sleeping in a bed with Cybela, implying that the two are involved in a relationship, or that one (or both) of them desire to be. In the epilogue, he is seen working under Viral's command alongside Cybela.
