As you may or may not know, Hasbro rushed Combiner Wars to market earlier than they should have, so wave one did not come with comic books. They are re-releasing them with comic books. Dragstrip is the only wave one currently available with comic. The wave one Aerialbots with comics are supposed to be out this month.
Here are links to my reviews of all the Stunticons. I did actually find a minor variation on the two Dragstrips I have, but I don’t have a photo. The one that came with the comic book has brighter red eyes than the first release.
Thanks for reading!
