And the last for this set; the various Unicron-related characters that have appeared thus far, or will appear soon enough.

On the right, you have Sideways and Nemesis Prime as they first appeared within the storyline (in 'Confrontations' and 'Signs and Portents' respectively). With them are Crosswise and Rook in their combined 'Rider' form and Dead End, and Nemesis Prime is holding the Dark Saber.

For reference, Crosswise/Rook and Dead End aren't proper Mini-Cons, simply Mini-Con-like critters, much like they appeared in the original series.

On the left, you have Sideways, Soundwave (with Laserbeak!) and Nemesis Prime in the back. Sideways appears this way as of 'Revelations', while Nemesis Prime will appear like this in Arc Three. Soundwave made his first appearance in 'Foundation', but didn't give his name until 'Galvanized'.

And the guy in the middle? Unicron himself. Well, an avatar anyway, set to appear in Arc Three.
