This model has been tested in WSF
This is a legends scale roller to go with your legends scale Optimus Prime toy. Optimus may not come with a trailer but that doesn't mean he can't have his little buddy with him.
This roller comes with plug in wheels and has a 3mm port on the top to accomodate any cyberverse/legends scale weapons. This little guy would work well with your Kreon collection too.
