Here you go... I just can't get excited about this movie. I'll be sure to make a rant sometime soon. Bumblebee is a Camero. That's retarded. From IGN:

Autobots

Optimus Prime - "The king!"

Bumblebee - "He's the same underdog character we always knew and loved." [Note: Except he's a Camaro in the movie.]

Jazz - "He's eager to take on the Decepticons."

Ratchet - "Ratchet, who was an ambulance in the cartoon, will appear in a new form."

Ironhide - "The muscle. A tough soldier who can make any Transformer bust an o-ring just with his stare!"

Decepticons

Megatron - "He's been portrayed as pure evil but we're trying to get a little bit behind the evil in this movie. ... He has a slightly less idealistic version of what he thinks humanity is worth."

Starscream - "Always secretly plotting to dethrone Megatron..."

Brawl - "An extremely pissed off Decepticon."

Bonecrusher - "The closest thing to a Constructicon in the film."

Barricade - "The hunter of the group -- a cop car."

Scorpinok - "Closest thing to Beast Wars or Dinobot in the film."

Frenzy - "A smaller form able to infiltrate spaces -- a stealth spy."

Blackout - "The guy who takes out our ability to fight back."

Transformers rolls out on the big screen on July 4th. Keep watching IGN for the latest
