Later Princess by JTVectorSigma
When Twilight stepped through Starswirl's mirror in pursuit of her crown, she wound up in a universe parodying the popular anime Gurren Lagann. Naturally, she joined up with the Alternate!Celestia to fight the minions of the evil Chaos Lord. This is an account of one of their most decisive battles: victory against the Northern General, Indigo Zapp, and her walking battle station!
