Cortex Castle

Cortex Castle is Dr. Cortex's first base in the Crash Bandicoot series. Even though it was set on fire at the end of the first game, it did survive and can still be seen in Crash Bandicoot 2: Cortex Strikes Back in the level Road to Ruin. A track based on it appeared in Crash Team Racing, as well as the Citadel City section of the same game, as players can clearly see many aspects of the castle within this area. Also, he used it as his base in Crash Nitro Kart before being abducted by Emperor Velo XXVII.

Development
During Crash Bandicoot's development, Cortex Castle was concieved more as a fortress than a castle tower. It was to be set atop a snowy mountain on Cortex Island. Atop the castle, Cortex's boss fight would take place.

Overview
The castle is located on Cortex Island, and debuted in the original Crash Bandicoot as the residence and base of operations of the game's main antagonist, Dr. Neo Cortex. According to the game, the castle was powered by the Cortex Power factory, a factory powered by a gargantuan nuclear chamber and owned by Cortex's minion, Pinstripe Potoroo. Crash's main goal in the game is to make his way to the castle and rescue his girlfriend, Tawna, from Cortex, who plans to use her for genetic experimenting in his Cortex Commando army. Inside the castle, the player battles Cortex's assistant, Dr. Nitrus Brio, as well as Cortex himself. After defeating Brio, some of the chemicals he was using to combat Crash set the castle alight, leaving Crash to flee through Cortex's lab and onto his airship where the final battle takes place.

However, the castle also appears in the beginning of Crash Nitro Kart and as a track in Crash Team Racing, indicating Cortex rebuilt it. It has not been seen since.

Crash Bandicoot 2: Cortex Strikes Back
In the alternate ending epilogue for the original Crash Bandicoot, it is stated that Papu Papu sold the ruins of the castle to a resort developer and used his newfound wealth to create a souvenir shop on the island, implying the fire destroyed the castle. However, the ending is most likely non-canon, as the castle is shown to be intact in the sequel, Crash Bandicoot 2: Cortex Strikes Back. The castle can be seen in the ruin levels and the introduction in Crash Bandicoot 2: Cortex Strikes Back. The instruction manual implies that Cortex examined his discovered crystal in his laboratory, implying he resided in the castle for a short period before leaving to create the Cortex Vortex. In addition, the castle also appears to contain the secret warp room housing levels 26 and 27. During the end of the game, the castle is also shown to contain N. Brio's base of operations where he destroys Cortex's space station with his laser beam. It is possible that Cortex regained his castle from the resort developers and rebuilt certain parts of the castle before leaving. This is supported by the fact that certain parts of the secret warp room appear to be destroyed, indicating that N. Brio secretly used the castle as his base of operations after Cortex left.

Crash Nitro Kart
Cortex Castle is seen in the intro, where it is again Cortex's base of operations, where Cortex, N. Gin, Tiny, and Dingodile are seen. The Evolvo-Ray is again seen when N. Gin attempts to zap a kart with it, but Tiny accidentally flattens Dingodile who was about to activate it. Then the tower that they're in gets abducted by Velo and later sent back to earth when Team Cortex accepts Velo's challenge.

Interior
The inside of the castle is really dark. It requires Aku Aku to act as a light sources. Part of the castle is a prison and another part is Nitrus Brio's lab.

Hallway
Inside the hallways, there are many items bearing Cortex's "N" insignia. The hallways are inhabited by spiders and rats. The castle pillars are decorated with spikes and gargoyles

Evolvo-Ray Room
This room contains the Evolvo-Ray, as well as a small lamp, a window, and a table for zapping animals with the Evolvo-Ray. It appears in Crash Bandicoot and Crash Nitro Kart.

Cortex Vortex Room
The Cortex Vortex room is the room that contains the Cortex Vortex, as well as its controls, and a window. There is another area of this room with various cages for the animal subjects.

Machinery Room
This is a room that contains various robots and devices. In game, it is the Castle Machinery level.

Nitrus Brio's Laboratory
N. Brio's Laboratory is a small lab where N. Brio does his experiments. It also has two desks and a fenced opening.

Laboratory
The Lab is a set of hallways with technology and Lab Assistants. There are also areas of this room/hallway that contain several spiked pillars in a dark pit.

The Great Hall
A room where Tawna is kept, there are also two balconies and a picture of her. Most of the hall is one giant pit.
