Ryker, a 17-year veteran of the Transportation Management Safety Team (TMST), not only lives by the book when it comes to airport accident investigations, he wrote the book. Nothing slips by this air safety investigator, so don’t even try.
At the end of Planes, he is seen in the crowd celebrating Dusty Crophopper's victory.
In Planes: Fire & Rescue, after a fire was put out at Chug and Dottie's Fill n' Fly when Dusty accidentally clipped the tower while testing his limits with his gearbox damaged, Ryker arrives in Propwash Junction the next day along with his pitty Kurtz, accusing Mayday of the accident until Dusty explains what he did. Ryker then figures out that the town has no plans for emergencies, and decides to close the airport down until Mayday hires a second firefighter.
At the end, he re-opens the airport after Dusty comes back to Propwash Junction with the news of being certified by Blade Ranger as a firefighter.
