The greatest commander after Optimus Prime - Ultra Magnus

A commander could want no finer a soldier than Ultra Magnus. Despite his incredible fighting skills, courage and unmatched talent for improvisation on the battlefield, Ultra Magnus is most comfortable when carrying out orders, and is naturally uncomfortable if the mantle of leadership should ever find itself placed upon him.

In Ultra Magnus's mind, he is a follower, not a commander, and his reluctance to change that will see to it that he expends all options before accepting the idea that he is required to lead. And when that time comes about, there is no question that he is resolute, fair and courageous, ever-ready to sacrifice himself for the greater good of his companions and mission, and unyielding in preparation for protection of those under his command. Although not interested in overall command, Ultra Magnus was the City Commander for Autobot City.

Jazz is the Man

The vehicle mode is a Martini Porsche 935 Turbo racing car. Self-possessed, calm, and utterly collected, Jazz is head of Special Operations, with his own dedicated roster of agents. He often gives the most dangerous assignments to himself. It's not a matter of ego—he just really is the coolest head for the toughest missions. Jazz's ease extends to whatever environment he finds himself in, no matter how weird or wonderful. He effortlessly tunes in to the local culture, assimilating and improvising, and making creative command decisions, making him an indispensable right-hand bot to Optimus Prime.
