Huh. They're actually not that bad. Even more attractive is that Optimus Prime and Megatron come with extra parts. Nifty.
Strange that the Triplechangers have to partsform in order to transform. Judging by the initial reveals back at Toy Fair, one would think no partsforming was required. Perhaps there's a loophole.
Not liking the heads of both Optimus and Megatron. Especially Megatron, with his grimace that could rival even that of Beast Wars II
Overall, I'm pleasantly surprised about these. I'll probably nab one or two of the smaller packs, Starscream maybe. I'd be much more interested in custom sets, where you can build your very own Transformer character instead of iconic characters.
