The Optimus Prime truck featured in “Transformers: The Last Night” movie released in June will be making an appearance in Hermiston this weekend and participating in the Umatilla County Fair kickoff parade.

A Western Star 5700XE, customized for the movie, will be on display before the parade at Triple M Truck & Equipment, 77765 Westland Road, in Hermiston from noon to 3 p.m. on Saturday before the parade, according to Ryan Medelez, general manager of Triple M.

“We were able to get the latest version of Optimus Prime truck model to be at the parade for the Umatilla County Fair here in Hermiston,” Medelez said. “This truck model has been in the last two Transformer movies.”

The customized truck travels around the country for promotional purposes at trade shows, charity events and other functions promoting the Paramount picture movie franchise and Western Star.

Medelez said a standard 5700XE will accompany the customized truck in the parade to allow people to see the difference between the truck customized for the film and the standard over-the-road truck.

The Umatilla County Fair Parade, which kick off a week of fair activities, starts at 6:30 p.m. in downtown Hermiston, west on Highland Avenue from Hermiston High School, north on Southwest Seventh Street, east on Hermiston Avenue onto Gladys Avenue, south on Northeast Third Street, west on Main Street to West Locust Avenue, ending at West Orchard Avenue near the post office.
