I will list some TFs from G1, its the series I am most familiar with, and you must cast the voices. It could be anyone: singer, actor, TV, film, whatever. You can also add a bot or two. Or three, four, five if you wish. Here goes; Optimus Prime: Ratchet: Wheeljack: Bumblebee: Jazz: Grimlock: Blaster: Perceptor: Arcee: Ultra Magnus: Megatron: Starscream: Soundwave: Shockwave: Thrust: Astrotrain: Blitzwing: Cyclonus: ...have fun.
