What do you mean, you can tell I was designed as a toy first?

Undertone might be quietly implying something.

The packaging photo actually took some effort.

The first version of Undertone released, dubbed "Scorch Strike Undertone", comes in "desert"-themed ocher colors. He transforms from a small humanoid robot into a spheroid in a single step. As a Cyclone-style Mini-Con, he can attach to and launch from the Deployers Crazybolt and Overload... who are both Decepticons. Huh. He comes with an Autobot-sigil-shaped sprue with a number of clear plastic armor pieces that can be attached to him in both robot and sphere modes. He shares engineering with, but is not a retool of Major Mayhem.

This four-pack also comes with Blizzard Strike Backtrack, Scorch Strike Beastbox, and Blizzard Strike Swelter.

Curiously, there exist two sets of promotional stock photos for the Mini-Con 4-Pack: The first set features Undertone in different colors, with white being the predominant color, whereas the second set depicts the final colors. No explanation for the color change has been given. All three photos simply replace Undertone himself while keeping the other three figures unchanged. For the the robot and alternate mode photos, this wasn't particularly difficult, as the figures are depicted against a white backdrop. For the packaging photo, the old version of Undertone was actually edited out and replaced by the new version, rather than taking a new photo of the figures in packaging entirely.
