- "Time Force Yellow!"
- ―Roll call
Katie Walker is Time Force Yellow of the Time Force Rangers.
History
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 reserved 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.

Split History
Shattered Grid

Time Force in Shattered Grid
When events set into motion by Lord Drakkon caused the timeline to split into pocket universe, each anchored on a powerset, the Time Force Rangers were split off into their own pocket universe.
Based from Outpost One, the Time Force Rangers investigated a fracture in space time, caused by interference in the past, which endangered the entire multiverse. Katie noted its size and its danger. In an attempt to repair it, an explosion pierced the Megazord, resulting in the Green, Yellow and Blue Rangers being sucked into the fracture. COMIC STORY- Mighty Morphin Power Rangers (Boom! Studios) Issue 25
When the timeline is restored so is Katie.
