Terykai is the brain of the Z-Fighters, using her new skills to track and study villains. She is not the most powerful of the Z-Fighters, but she is without a doubt the smartest member. Actually, she was always intelligent, but when she was a member of the Shadow League, she hid her intelligence to avoid being teased by the others.
Terykai's personality is basically the same as Shimmer's.
Gem Powers- See Shimmer.
