Like many stereotypical villainous mad scientists, Cortex holds a grudge against other scientists for ridiculing his outlandish (yet workable) ideas, and was originally driven towards world domination by the desire to prove his colleagues wrong. Another notable personality trait is his stubbornness and inability to plan ahead or learn from his mistakes; he often relies on his minion Tiny Tiger to eliminate Crash by himself, despite the fact that Tiny is too incompetent to do so alone. This impulsive behavior is first witnessed in the opening cinematic of Crash Bandicoot, in which Cortex refuses to heed the warnings of his then-henchman Doctor Nitrus Brio and tries to make Crash the general of his army, despite numerous past failures.
