Cortex Island (also known as the Iron Island) is the third island in the Wumpa Archipelago that previously served as Dr. Cortex's primary base in the series.


Formerly known as Iron Island, Cortex Island is a mountainous region heavily affected by Cortex's activities. Its most notable feature is Cortex Castle, a tall, foreboding tower which serves as Cortex's base of operations. Closer to the shore are the factory and generator that power it. The power plant spills sewage into the surrounding ocean. Cortex Island is also home to ancient temple ruins, one of which was where Uka Uka was imprisoned.


According to the Crash Bandicoot production bible, the island was once inhabited by an ancient tribe known as the Lemurians. Much later, it served as a shelter for Cortex and N. Brio, who were wanted by various international law organizations. The construction of the power plant and the unregulated sewers beneath it changed the island's environment radically, causing it to be polluted with toxic waste refinery. Robots and mutants were appointed to patrol it. The castle was constructed via unknown means by Cortex and Brio, and was built into the ruins of an ancient temple when attempts to demolish it failed.

During the events of the first game, Cortex Island is the last island Crash travels to. After escaping from the castle, he returns to defeat Cortex and his thugs, sabotage the facilities and save Tawna Bandicoot.

In the second game, the levels of the third and fourth Warp Rooms take place on this island. Both N. Sanity and Wumpa Island can be seen in the distance from the secret sixth warp room, implying that the warp rooms themselves are located here. Promotional art depicts the island power plant as completely abandoned and decayed since Crash’s last visit.

In third game, a piece of the destroyed Cortex Vortex space station falls towards the island, destroying Uka Uka's temple prison.

In Crash Nitro Kart, a part of the castle was abducted from the island and transported to Emperor Velo's planet.

The island serves its original purpose from the first three games in the N. Sane Trilogy.

It returns in It's About Time, via Flashback Tapes and later on, time travel.
