Tinga was one of the 12 X5s from the '09 Manticore escape. Her designation was X5-656.
Post-Escape
Tinga took the name Penny and married a man named Charlie Smith with whom she had a son they named Case. As Penny, Tinga worked in a Bakery. She told Case a bedtime story about a castle with an evil king (Donald Lydecker) and twelve princes and princess who were badly treated (the 12 escapees).
Location Compramised
When Tinga's location was compramised, Zack and Max came to Portland to help rescue Tinga. She and Zack then travelled across the border into Canada where they were to stay in hiding.
When Tinga learned that her husband had placed a missing ad for her on a milk carton that would lead Lydecker and Manticore to her family, she returned to Portland to help her family only to find Max. They, along with Zack, managed to escape Lydecker with Tinga's family. Safely at Logan's apartment, Case came down with an illness and an unusual barcode appeared on his neck, this barcode was Lydecker's private phone number. A deal was made to have Case cured in exchange for Tinga. Once Tinga handed herself over, Brin called for troops to move in and capture Case and Max. Zack arrived and together they managed to fight off the guards.
Recapture
After Tinga handed herself over, her was taken to a Manticore facility where she was placed in a tank and had tests run on her to see how she had managed to pass the X-gene onto her son. Zack searched for her and when he finally found her, he and Max went in to rescue her. Max found her in the tank, smashed it open, only to find Tinga dead. Tinga's death was the betrayal that caused Lydecker to go on the run and help the other X5s.
