Pre-Crash Twinsanity
When Nina was young, she showed 'disturbing' signs of a kind heart, so Dr. Neo Cortex sent her to the Academy of Evil for a few modifcations.

Crash Twinsanity
Some years later in Crash Twinsanity her uncle asked her to aid Crash and himself in their quest to defeat The Evil Twins.

Crash Tag Team Racing
After that she was in Crash Tag Team Racing racing along side N.Gin and Dr. Neo Cortex to collect all the Power gems.

Crash Of The Titans
In Crash Of The Titans she is Uka Uka's replacement for Dr. Neo Cortex, but she is was eventually defeated by Crash.

Personality
In Crash Twinsanity she really didn't have much of a personality. In Crash Tag Team Racing she had a love for violence with a bit of a gothic personality. In Crash of the Titans she basically had the same personality as in Crash Tag Team Racing.
