If your kids are Transformers fans, or your adults, a full size replica of Optimus Prime in truck form is touring around Lewiston-Auburn today and will be at the Great Falls Comic Expo on Saturday.

There are only 3 of its kind in the world and Optimus will start his tour at 11AM with stops at 11:30AM at Simone's Hot Dog Stand in Lewiston and 12:15 at Community Concepts and you just may see him rolling down the street anywhere in the twin cities. You can get updates on the Optimus is Here event page on Facebook.

Then on Saturday Optimus arrives at Great Falls Comic Expo at the Norway Savings Bank Arena in Auburn where you'll be able to get your picture with him and even sit in the driver's seat! Just don't expect Optimus to transform into a robot. He saves that for when the Decepticons are around.

Tickets are available now for the Great Falls Comic Expo. Doors open at 10AM and the show runs until 5PM. Grab them online or at the door and get info on the show by hitting the button below.
