Artenborough Cortich

Aretenborough Koachicchi (アーテンボロー・コアチッチ, Ātenborō Koachicchi?) is a hyperactive, impulsive, trigger-happy man, who is the gunner of Dai-Gurren's control team. He tends to fire at enemies or move Dai-Gurren without warning. After the timeskip, he joins Leeron's science team and still appears to have his hyperactive nature. After Team Dai-Gurren moved to Super Galaxy Dai-Gurren, he assumed the same position he had before at the weapons control. Curiously, this trait became one of Tengen Toppa Gurren Lagann's attacks. He randomly showed up in the series one day, later it was confirmed that he snuck into somebody's luggage, and that is how he joined Team Dai-Gurren. Also, given how much he enjoys fireing at enimies and his love for explosions. It's quite clear that his fighting spirit alone was able to create 99.99% of the Tengen Toppa Gurren Lagann.
