Being a pre-teen and the youngest of the group, Raf is understandably timid but he is loyal and dedicated to the Autobots, especially his friend and protector, Bumblebee. When the situation calls for it, he can muster the courage he needs to complete the task at hand. His kind and pure demeanor has an effect on those around him, particularly the strict Ratchet, who states, when Raf is almost killed by Megatron, "[He has] grown to need him."
