Titan

Titans are creatures mutated with Mojo to become extra powerful in a process called "Mojo Mutation." Uka Uka first taught Dr. Cortex this process in Crash of the Titans, and Cortex progressed to create a large army of loyal mutants by using a modfified Evolvo-Ray. Titans are called Mutants in Crash: Mind Over Mutant.

Uka Uka later used this device to mutate himself, proving not only animals can become Titans. By placing Aku Aku on a Titan's face, Crash Bandicoot has the ability to "jack" Titans, meaning he can control them while riding on their backs. After the events of Crash of the Titans, the Titans began building villages in Wumpa Island, as they haven't migrated to the other two islands (N. Sanity Island possibly being too far away and Cortex Island is uninhabitable), the most noteworthy being the Ratcicle Kingdom.

In Crash of the Titans, titans cannot jump and the jump button for Crash is a Special Attack button for them. Only Battler can make a (very high) jump. In Crash: Mind Over Mutant, all Titans can make a single jump.
