I can bring in Thundercracker, and Soundwave with some of his mini's as NPC's. Maybe Blitzwing too, for the Cons, They'd be NPC so everyone could play them 
For the Autobots I can do Prowl, Sides and Sunny. I could do OP and some of the other Main bots too but I figured I would leave those for others. 
Just let me know.
