Cortex Island

Cortex Island is an island in the Wumpa Islands that previously served as Doctor Neo Cortex's primary base in the series. The castle on the island was destroyed after the events of the first game, but it was rebuilt and briefly used by Cortex in Crash Nitro Kart before being abandoned again. The island is also home to an ancient temple that resembles the Mojo Temple on Wumpa Island.
