May be mistaken on 2. but The Fallen (Megatronus Prime) is in the foreground, Amalgamous Prime is the one with the horns, Beast Prime is the one with the wings, I think the big one is Liege Maximo, but it may be Nexus Prime, both are pretty large, but given the villain prime theme I think it is Liege.... dunno the last one in the background... possibly Alchemist Prime.

@Obsidian609:  Just wish they would give Beast Prime an official name, unless Beast Prime is now his official name, like that he has wings and paws,,, a Gryphon like BW Silverbolt. As for me knowing who is who at a glance, we all have one weird talent, mine is identifying Transformers :)
