Bumper

Bumper is a supporting character in the Digital Circus; he resembles a marching band bandmaster. The crew tend to believe that he is also an AI simply due to his nature, but he is also human.
Bumper is curt, indifferent, and strangely realistic, not giving into the zaniness of the circus and remaining withdrawn. The crew aren't exactly keen to talking to him, but he surely talks to Caine more than anyone else. His uniform resembles Caine's ringmaster uniform, and he sometimes wonders if that wasn't a coincidence. He frequently wears his cap over his eyes-his reason is that the circus is far too bright for his tastes.
