Tengen Toppa Solvernia has no smaller mech from which it draws its design, as Nia has never piloted anything on her own previous to it. Instead, its design is very similar to Gurren Lagann, but with feminine proportions and a blue-and-white colour scheme. Its eyes are yellow, with red cross-like pupils similar to its pilot. A mass of light blue Spiral Power, resembling Nia's hair, is emitted from the back of its head. It is the first of the Tengen Toppa mechs to appear after the Granzeboma destroys Tengen Toppa Gurren Lagann.
