Nadira is vain, childish, self-centered, greedy, and vicious. She is also a very loyal daughter to her father, Ransik. The first time we see her, she is plotting to help Ransik escape from his imprisonment by Time Force. She goes with him through time to the year 2001, and assists him in his various schemes, occasionally coming up with a few of her own.
Nadira seems purely evil at first, except for her affection for her father. In 'Force From the Future, pt 1', she commands her cyclobots to destroy Jen. In 'Bodyguard in Blue', she kidnaps and threatens to torture Dr. Zaskin. In 'A Parting of Ways' she is shown ordering the destruction of a group of children she has taken hostage, an act which would seem to indicate the depths of her evil nature.
However she also has a romantic side, and tries to start a relationship with Lucas when she thinks he is secretly in love with her. At the end of the series, after assisting a woman to give birth, she (rather suddenly) develops feelings of compassion towards humans and towards Frax. By the last episode she has completely freed herself of the hatred and anger her father taught her.
There is a hint in 'Reinforcements From the Future, pt 2' that she even starts that relationship with Lucas, after all.
Nadira is fond of watching television, especially cartoons. She also likes to go on shopping sprees, although her idea of shopping is often synonymous with stealing.
