Demon Battleship
The Demon Battleship is the final boss of Rogue Galaxy.
Story[]
The Demon Battleship is encountered on Mariglenn after Jaster and his companions defeat Mother's second form. Valkog arrives on the Emperor with Norma and Izel and attempts to collect the Rune from the core of Mother's Lair, but the Rune engulfs the ship and the three villains fall into the crater. The ship is dragged in after them, and the Demon Battleship - a grotesque fusion of the Emperor, Valkog, Norma, and Izel - emerges from the crater soon after. Queen Freidias appears and gives the party the Drigellum of Prayer, which allows Jaster to create a sword even larger and more powerful than Zeo Sychros that he wields as he channels the Star King's power.
Arguably the hardest boss in the game, the Demon Battleship is eight different bosses combined into one. It consists of Valkog's Left and Right Hands (each of which is a different color), a pair of Bomb Walkers (each of which is backed up by gun batteries), the Core (which is protected by a regenerating Bomb Walker), Izel (who has fused with the ship's mast), Norma (who has fused with the ship's figurehead yet is still surprisingly good-looking), and Valkog (whose head has fused with the ship's main cannon). Jaster and his companions divide and conquer: Deego and Jupis fight the hands (Valkog's Right Hand and Valkog's Left Hand, respectively), Simon and Steve fight the Bomb Walkers, Lilika fights the Core, Zegram fights Izel, Kisala fights Norma, and Jaster fights Valkog.
Defeating all the parts of the Demon Battleship triggers the game's ending.
