According to www.latinoreview.com the character of Alice, as played by Isabel Lucas, in Transformers: Revenge of the Fallen, is a Pretender.

 Pretenders are Transformers that are hidden inside a shell that acts as their disguise. In the case of Alice, the shell will be an attractive human woman while the inner robot is best described as a hybrid of the Frenzy robot design from the first movie. The Pretender Transformer will have an arm that transforms into an energy weapon, a long tongue, and a scanning tenticle.
