Robots in Disguise (2015)

"Combine! Dino Mission!!!"

• Grimlock & Optimus Prime (Crash Combiners, 2018)

This two-pack features a roughly Scout-sized Optimus Prime and Grimlock, which can transform from vehicle/dinosaur to robots, or combine to form Primelock.

This two-pack was a very late addition to the Robots in Disguise line, with a Hasbro product code number in the same region as the wave 1 Prime Masters from Power of the Primes.

As with Saberclaw, Primelock never made an appearance in the mobile game, rendering the badge ornamental and meaningless for the scanning app. The badge seen in the stock photo can be identified by the app, but scanning it unlocks the 2016 One-Step Changer Sideswipe figure instead.

Buzzworthy Bumblebee

"Gashin! (Go! Go! Go! Go!)"

• Grimlock / Optimus Prime (Crash & Combine, 2021)

Primelock was redecoed as part of the Buzzworthy Bumblebee branding. This release gives Optimus yellow highlights in combined mode, while Grimlock is predominantly grey and blue.

The packaging features recoloured artwork of the previous version of Primelock, though glaringly Grimlock and Optimus are individually represented by "evergreen" character art.

This set was exclusive to Target in the United States.
