Perhaps, but the only reason they succeeded was because the Anti-Spiral underestimated them. Had it used it's full power from the start, they would have been annihilated long before creating Tengen Toppen Gurren Lagann.

Make a character. Most power levels are allowed, although based on the two possible characters already in the roleplay, it's quite possible that this will be fairly low-powered, probably taking place near the Lost Worlds. Unless you want to add a char for the Amalgam Alliance.
