She's one awesome motorcycle -- sleek, fast, and powerful. Arcee is also the Autobots' best soldier. She has a special bond with Optimus Prime and is his 'go-to' girl. As the least 'flawed' of the Autobots, she's the one they can always count on. She wasn't too thrilled to get the job of looking after the human, Jack Darby, but she slowly comes to respect him as a partner.
Leader of the Decepticons, he's as bad as the Autobots' leader is good. Whether in alien fighter jet form or robot mode, Megatron's the most evil and deadly of all the Transformers. He despises how much Optimus Prime cares about Earth and its weak humans, so he won't stop until he defeats ALL the Autobots and makes this planet his own.
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.
