The Fortress of Altitude[1] is an object that appears in the Sonic Underground television series. It was a giant spherical flying fortress created by Dr. Robotnik.

Description[]

Appearance[]

On its exterior, the Fortress of Altitude was a spherical fortress with several cannons, windows, and pipes protruding from its sides. On its interior, it featured a cockpit with controls and surveillance screens, several narrow winding corridors, and a circular reactor room.[1]

Features and traits[]

In addition to flying, the Fortress of Altitude was capable of mass bombardment, and is heavily armored with Mobobendium plating. Additionally, it featured a Chaos energy-based defense system that vaporized any intruders in the corridors with a green wave of energy. However, the entire fortress was powered by a Chaos Emerald, and would fall like a stone if it was removed from the reactor.[1]

History[]

TV series[]

Season one[]

Dr. Robotnik created the Fortress of Altitude, powering it with a rare Chaos Emerald. Robotnik than used the Fortress of Altitude to terrorize several areas on Mobius from above, but was met with resistance from the Sonic Underground. Despite the best efforts of the hedgehogs, however, none of their attacks could even dent the Mobobendium armor plating the Fortress of Altitude, forcing Sonic to infiltrate it directly by sneaking through one of the cannon barrels. However, before Sonic could find the ship's power source, he was forced out by its Chaos energy systems, with two Stealthbot soon being dispatched from the Fortress of Altitude to hunt him down. Robotnik then used the Fortress of Altitude to bombard the area, before flying it over to Port Mobius for revenge against the citizens for betraying him. But before he could bombard the port, the Sonic Underground (plus Knuckles) broke through the Fortress of Altitude's armor, and infiltrated it in search of the Chaos Emerald. However, Sleet and Dingo managed to steal it first, and escape with it, believing Robotnik would roboticize them otherwise. This caused the Fortress of Altitude to drop into the ocean and sink to the bottom, but not before Robotnik, Knuckles, and the Sonic Underground escaped it.[1]
