Transformers Animated TA-33 Rodimus

To call the commander of Team Athenia a prodigy is an understatement. Though his drill sergeant Kup took him for a turbo-revving punk at first, Hot Rod, the young bot who would one day be called Rodimus Prime, distinguished himself during a live-fire exercise by throwing himself in front of a grenade to save his mentor. From there the higher-ups took special interest in him, and he was accepted into the Autobot Academy a full decade before his boot camp peers.






In the Academy he continued to dazzle command, mastering servo-to-servo combat and a wide arrange of weaponry, as well as designing the energy bow that became his signature weapon. Some even began to refer to him as the "chosen one" after seeing him in action, and when he became the youngest Autobot to be assigned his own command, many felt he was on the fast-track to becoming Magnus.
