The symbol of Team Dai-Gurren is a flaming red skull with Kamina's signature red sunglasses. However, after the timeskip, most members wear a simple 5-pointed star, as they have become key members of the Earth's new government. High-ranked members wear two stars in their chest, and Simon, being the commander-in-chief, wears three. Rossiu also wears a large one on his back in the epilogue shaped similar to Simon's glasses; it could be an indicator of rank (he's president) or possibly the government's official logo.
