I see what looks like Megatron on the far left. Grimlock, Wheelie, and a Sharkticon recreating the scene where the Dinobots rescued Cup and Hot Rod from the Quintessons. Arcee, Hot Rod with the Matrix of leadership, Unicron, Scourge, Cup, Blur, and Wreck-Gar. :D

Yep, you are correct! Unicron was a tall order - had to get him from Japan since he was made by a 3rd party, but it's by far the best and most accurate version of him made to date. 👍
