The ISS Phineas PF-01 is a cold fusion-powered Flynn Class starship that is recognizably similar to the USS Phineas of the Prime Universe. The ISS Phineas is the flagship of the Terran Empire, an earth-based empire in a parallel universe that seeks the conquest of all other worlds possible. It was constructed in the Doofenshmirtz Shipyards in 2010 as the first prototype warp-powered starship for an imperial navy of starships (Balance of Terror). It has the same general design as the USS Phineas, but has more torpedo tubes that protrude from the saucer hull, both fore and aft. It also has the Terran Empire insignia and a yellow-rimmed saucer. It was used by the Terran Empire counterparts of Phineas and his friends in The Great Temporal Battle against their Prime Universe selves in The Terran Empire. It suffered a hull breach where some of its Fireside Girl engineering crew nearly perished by being sucked out into space from the hull compromise. It aided the anti-Terran Empire opposition in A New Star is Born, where Emperor Heinz Doofenshmirtz is peacefully dethroned.
