Ken

Ken is a minor face glimpsed in the sprawl of New New York, one of the many small parts Billy West drops his voice into as Futurama fills out its universe. He appears briefly, does what the scene needs, and moves on without demanding the spotlight.

The pleasure here is craft rather than character arc: West slips into another register, another rhythm of speech, and disappears into it so completely that the joke of Futurama's tiny voice cast becomes invisible. Ken exists to prove how deep that bench of voices really goes.
