He is voiced by Kissho Taniyama in the Japanese version and Christopher Corey Smith in the English version.
Kittan is a tall man with a well-built physique and spiky blonde hair. Originally, he wore a black, sleeveless shirt, black pants, and black shoes, but after the 7-year time skip, he had a new outfit similar to his old one, but was more dark blue as opposed to black, and had various red and gold details.
Kittan is shown to be egotistical and shares similar traits to fellow Team Dai-Gurren member, Kamina. After Kamina's death, Kittan considered himself to be the team's new leader, even though no one else agreed.
Kittan piloted a gunman he stole, and then proceeded to rename it "King Kittan". It's a pointy, yellow robot that's slightly larger than Lagann. In a parallel works story, It would evolve into "Tengan Toppa King Kittan" in the same way Gurren Lagann did in the final episode.
