Silverbolt

The leader of the Aerialbots. Transforms into a Concorde jet, forms the torso of Superion. He is afraid of heights, because he was built from a low-altitude transport, as opposed to the spacecraft his comrades were made from. Optimus Prime gave him command of the team so that his concern over the well-being of the others would take precedence over his irrational fear. As a result, it was a while before the others accepted him as their leader
