I found the last two 2-packs from the Robot Heroes second wave this afternoon.  The are Optimus Prime opening the Matrix versus Unicron and (Autobot) Jazz versus Thundercracker.  The entire Heroes line rocks, from Star Wars to Marvel and now Transformers.  My only regret is getting rid of most of my Star Wars Galactic Heroes.  I do still have a Bossk, Hammerhead, Figrin D'an, and a couple different R2s and 3POs though.

I never thought I'd see the day where Unicron, of all characters, would look so darned cute.  He's the same size as the rest of the line, so this figure must represent him early in his planet-eating career .  I would have thought Prime would be the same mold as the one that came with Ravage only with new arms.  But, he's a completely new mold.  Both figures feature movement at the shoulders and that's it.  Fortunately, super articulation isn't what makes these so awesome.  It's the cute-factor.

Thundercracker shares his mold with Starscream (and Skywarp from the Wal-Mart exclusive 5-pack of mold sharing Robot Heroes).  It works well enough, but Starscream's smirk looks out of place on him.  But, TC is not why I bought this set.  No.  It was for the Jazz-Meister.  Get it?  Eh, nevermind.  Even in a cutesified, child-oriented figure, Jazz does it with style.  And while there's no doubt who this figure is, I take issue with the doors being opened.  Jazz didn't play like that in the cartoon.  Still, he's the shining star in this line.
