Thundercracker

Thundercracker looks down on those who cannot fly with sneering disdain, often going out of his way to attack creatures that cannot fly, just to prove his superiority. It was this attitude that led to him being recruited into the original seekers squadron alongside Starscream and Skywarp. Though his loyalty to the Decepticon cause is less than total, the fact that he is allowed to indulge his impulse to assault those he considers inferior keeps him flying for Megatron.
