"Time Force Yellow!"
Katie Walker is Time Force Yellow of the Time Force Rangers
Katie was a Time Force detective who went back in time to 2001 along with teammates Jen Scotts, Lucas and Trip. Gifted with unnatural strength that might be the product of genetic engineering, Katie is always open with her feelings, a sharp contrast to the conservative Jen. She is shown to be very affectionate and loving to her teammates, especially to Trip, who she is seen usually hugging or being overly protective of and consoling him like in "Uniquely Trip" by telling him "We'll call you if we need you" when Jen told him to stay, at the end of the episode she was seen hugging and kissing Trip.
She is also very kind and always gives a hug to whoever needs it. She also likes to tease Lucas with his constant mirror gazing like in "Reflections of Evil" and also looking into his personal book and reading it out loud during "Nadira's Dream Date". After returning to the future, she comes back one more time to help fight the Mut-Orgs. After the battle, she challenged Danny, the Black Wild Force Ranger to arm wrestling and where she easily beat him (which Princess Shayla and Merrick were shocked at).
She is also shown to love her family a lot like in the episode when she was devastated to hear that the future was being altered, she fearing of what could have happen to them.
Katie and the other Time Force Rangers returned as part of the army of Legendary Rangers that helped the Mega Rangers defeat the Armada once and for all, fighting in a huge battle against hundreds of X Borgs and dozens of Bruisers.

Time Force Yellow
The Time Force Yellow Ranger Key is Katie’s personal ranger key. This key along with the majority of the Core Ranger Keys are seen lining the Command Center's interior walls. This key is mainly used by Gia Moran (Super Megaforce Yellow) who uses it to fight as the Yellow Time Force Ranger. Although it has not been used yet, it has been seen in the Scanner app and the toyline.
