Gurren (グレン Guren?), was the Gunzar, a custom-class Gunmen piloted by a Beastmen commander before being revamped after its harsh day with the Jiha brother duo, the then "Team Gurren". After being supercharged with Simon's power, it forms the body of the titular mecha Gurren Lagann. It was initially piloted by the main character's brother, Kamina, then Rossiu, briefly Yoko, then Kinon, and finally, Viral.
