Invincible ( Final Fantasy IX ) The Invincible is an airship in " Final Fantasy IX " . Constructed by the Terrans , it is an ancient battleship geared for war and enslavement . Story . According to ancient Terran recordings at the ruins of Oeilvert , the " Invincible " was developed many times to refine it into a perfect tool of war . The final version was entrusted to Garland , who recognized its potential as a weapon . The " Invincible ' s " underside contains a large , crimson " eye " that fires a devastating energy beam and can enslave eidolons . The " Invincible " hosts numerous souls trapped within it , apparently absorbing them in events such as the Second Battle of the Iifa Tree , although the exact meaning of this is never explained . The " Invincible " is Garland ' s method of traveling between the two worlds of Gaia and Terra . The reason Kuja is never seen on - board the " Invincible " , even though he appears to work with it , is probably because , according to the " Final Fantasy IX Ultimania " , Garland has banished Kuja from traveling between the worlds . A young Sarah and her mother sailed away from the burning village of Madain Sari in a boat . Garland attacked the city with the " Invincible " in fear of the resident summoners ' ability to call forth eidolons , a talent that could hamper Garland ' s plans to assimilate the world of Gaia into Terra . Though Sarah had repressed these memories and soon assumed a new identity as Princess Garnet , the hazy memory of the eye in the sky keeps haunting her . Kuja , having gained control of the ship , uses it to possess Bahamut at the shores of the Iifa Tree and commands the eidolon to kill Queen Brahne . Princess Garnet attains Alexandria ' s throne , though her coronation ceremony is halted by tragedy . Kuja , relishing his new powers , sends Bahamut on a rampage through Alexandria , but the dragon ' s flames are quelled by the eidolon Alexander Garnet and Eiko Carol summon together . Though Bahamut is vanquished , Kuja attempts to enslave Alexander instead . This fails , as Garland , fed up with Kuja ' s insolence , appears on the decks of the " Invincible " and uses it to destroy Alexander . When the party ventures to Terra they spy the " Invincible " levitating above the entrance to Bran Bal . Garnet faints upon seeing the ship , realizing its significance . The heroes confront Garland within Pandemonium , but Kuja , having arrived to Terra on a Silver Dragon , steals the " Invincible " and , being a Genome , absorbs the souls residing within the ship into his body to achieve Trance . After Kuja murders Garland , Zidane and his friends — along with the resident Genomes — take control of the " Invincible " and pilot it back to Gaia . The party uses it to fly it into Memoria , but what happens to the " Invincible " after Necron is vanquished is a mystery , as it is never seen again after the party returns from the Crystal World . Gameplay . As a vehicle . Unlike the " Hilda Garde III " , the player may land the " Invincible " in desert areas on the world map . The " Hilda Garde III " is only capable of landing on grassy areas . Etymology . The " Invincible " is a recurring airship name in " Final Fantasy " games ( the first " Invincible " appeared in " Final Fantasy III " ) , but looks nothing like any of the airships that share its name . " Final Fantasy IX " makes numerous allusions to previous games in this manner . The title itself may originate from ' s story " " , where the " Invincible " is a very powerful and armed interstellar space ship .
