Repair crew captain Optimus Prime, once settled/stranded on Earth, typically used the command "Transform and roll out!" to have his squad deploy on a mission. adoring young fans among the population of Detroit requested that he say the phrase for them. Ultra Magnus later told Jazz to "Transform and roll out" when he decided that the two of them should deal with a runaway train.It became such a catchphrase for him that his
The Decepticons have their own version of the command: "Transform and rise up!" Megatron, Blitzwing, Lugnut and Starscream) have flying vehicle modes, hence the reason for the variation of the Command.It is also interesting to note that most of the Animated Decepticons (
