Some of the characters they cited to appear in the movie:
Autobots:
Optimus Prime
Bumblebee -- scout
Jazz
Ratchet -- a medical officer; in the cartoon, he was an ambulance; in the movie, he'll be some kind of emergency vehicle
Ironhide -- a tough soldier; classic cowboy; Optimus' oldest friend
Autobot Human:
Spike
Decepticons:
Megatron
Starscream -- obeys Megatron, but wants to overthrow him
Brawl -- an extremely pissed off Decepticon
Bonecrusher -- closest thing to a constructicon; hates all other Decepticons except Megatron
Barricade -- hunter of the group, scouting for Autobots; transforms to cop car as an ironic symbol of authority
Scorponok
Frenzy -- a smaller form, able to infiltrate around you and not be seen -- a "stealth spy"; can hide under desks
Blackout -- takes out the ability to fight back; hits electronics (EMP); is the biggest vehicle, transports other Decepticons
Fear not, if these characters (or the entire "Transformers" world) are not familiar to you; Orci and Kurtzman promise that the story will be accessible to the uninitiated while staying loyal to the legions of fans. They also say the story will be told through the eyes of its human characters, who are witnessing the intergalactic Autobot-Decepticon war come abruptly to Earth.
