G.I. Joe
Picking up from where issue #6 leaves off, Hound and Clutch are at odds but realize they can help each other and a familiar name helps them. Meanwhile, Cobra Commander's energon supply might be in jeopardy.
A nice interlude that expands on the end of issue 6 of the on-going G.I. Joe title. We get a bit of background on Hound and how he came to be reactivated. We also get to see a familiar face from the Cobra Commander mini-series make a reappearance. I did like this story but do worry that if someone skipped this issue, they might be a bit lost when they pick up issue 7 (though we'll see when it comes out!).
Transformers
Jazz is kicked out of his Cybertronian band but seems to be searching for something more. On Earth, he seems to have gotten closer to finding it.
A nice "slice of life" style story, we get to see Jazz on Cybertron playing in his rock band and, like on Earth, they have drama. This plays up to a lot of Jazz's personality we've seen over the years, with him being in love with Earth culture. It also is pretty safe to read without giving away too many spoilers for the on-going series nor is it critical to it either. Just a nice character-driven story.
Void Rivals
The Quintessons are happy to have a way to regain a powerful weapon of theirs, by using the Sacred Ring. Meanwhile, a jailbreak happens, led by our favorite rhyming robot, Wheelie. Curiouser, the Quints don't seem as worried about the jailbreak as they do the next phase of their plans.
Like the Transformers story, this one takes a break from the main Void Rivals story to give us some more background story and it's nice. We get just enough Wheelie to say he's there but not too much.
Overall, a nice Free Comic Book Day entry for the Energon Universe. I enjoyed that Void Rivals and Transformers kept their stories as "side stories" to the main plots going on. And the art for Void Rivals was quite good. The G.I. Joe art was nice as well, fitting with what's been established in the on-going series. The Transformers story does have the weakest art of the three.
