Gurren

Gurren (グレン), a modified Gunzar, is a Gunmen captured and piloted by Kamina. Upon being captured, it was revamped, now boasting the logo of Team Gurren and Kamina's trademark glasses. After being supercharged with Simon and Lagann's Spiral Power, it forms the body of the titular mecha Gurren Lagann. It was initially piloted by Kamina, then Rossiu, briefly Yoko, then Kinon, and finally, Viral.

Plot
After attacking Littner, the mech is captured, rebuilt, and stylized by Leeron using salvaged parts from the three enemy Gunmen that were defeated in battle. It is subsequently named Gurren by its eventual pilot, Kamina, who had the Gunzar's original swords melted down into massive sunglasses similar to his own that can be detached and used as a blade or boomerang in combat.



Powers and Abilities
Being of typical Gunmen proportions, Gurren is able to fight tremendously without connection to Simon via the Lagann. While its individual power was initially not on the same level as more experienced opponents, Kamina eventually became experienced enough to hold his own in battle against multiple foes. After Kamina's death, Gurren was mainly piloted by Rossiu and one-time pilot with Simon, Yoko, until the aftermath of the battle of Teppelin. Though it remained under Simon's control most of the time, it was briefly piloted by Kinon, until Viral became the Gurren's official pilot during the battle against the Anti-Spirals.

While paired with Lagann, Gurren is able to, like the former, produce drills from virtually any part of its body, and use these drills to combine with other mechas such as Cytomander's Gunman bombers and Arc-Gurren, the former combination giving Gurren the ability to fly from that point on.

Gurren while combined with Lagann can also regenerate any damage it takes in battle, however once Lagann separates from it, the damage comes back as if it was never fixed at all.

Etymology
Gurren (紅蓮) means "Crimson Lotus". As homage to it, a white Gunzar unit is seen during the battle of Teppelin, sporting a pair of pistols rather than blades.
