Gurren

Gurren (グレン, Guren?), originally named the " Gunzar ", is initially an above-average sized Beastmen-piloted mecha.

Plot
After attacking Ritona Village, the mech is subsequently captured, rebuilt, stylized and named by its eventual pilot, Kamina, who had the Gurren's original swords converted into massive sunglasses similar to his own that could be used as a blade or boomerang in combat.

Powers and Abilities
Being of typical Gunmen proportions, Gurren is able to fight without the Lagann's power. While its individual power was initially not on the same level as advanced Gunmen/pilot pairs, such as Viral and his Enki, Kamina eventually became experienced enough to hold his own against multiple enemies. After Kamina's death, Gurren was mainly piloted by Rossiu and one-time pilots until the aftermath of the battle of Tepplin, pilotless until Viral becomes the Gurren's official pilot during the battle against the Anti-Spirals.

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