The Autobots' leader is the biggest, strongest, and smartest of them all. He's always awesome, whether he's in big-rig mode, or as his blazing red-and-blue-armored self. Optimus Prime runs the team in all things, including protecting the humans from danger as he and the Autobots continue in the war with the Decepticons. You wouldn't call Optimus Prime 'cuddly', but he does care. He's just seen a lot of battle ... and he knows there's more to come.
This military fighter jet is Megatron's right-hand man, who doesn't mind fighting dirty. Starscream would rather sneak up on his victims than face them head-on, which makes him extra-dangerous. He's an expert planner, and that's one reason Megatron keeps him around. And while Starscream always shows respect to his general, he's really just waiting for a chance to take command of the Decepticons himself.
He was just a hard-working kid slinging burgers to save up for his dream...a motorcycle. Then Jackson 'Jack' Darby meets Arcee, his guardian Autobot and his dreams come true. Talk about SCORE! Jack gains a killer bike AND a big sister all in one. With pals Miko and Raf, he helps the Autobots fight the Decepticons. Jack's usually smart and responsible, guess that makes him a leader ... except when he wants to impress a girl.
