Z spent most of her life living on the streets - helping the homeless by stealing from those more fortunate. She desired to be a part of something bigger, and when arrested by S.P.D. was offered that chance by Commander Cruger when he made her the Yellow Ranger. Z is the one who always looks out for those who are less fortunate or being picked on.

When young Sam was picked on by his peers for being different, Z remembers what she went through as a child and comes to Sam's aid. When Z was only 12, she was ridiculed for her genetic abilities and was once saved by a mysterious person in the shadows. The person turned out to be none other than Commander Cruger. This inspired a desire to protect others. Through S.W.A.T. training on Zantor, Z learns to get over her differences with Syd and together as a team, the Rangers take down a renegade A-Squad.

When Jack leaves S.P.D., Z stays with the Rangers and continues to live out her dream of protecting the innocent.
