Blek

Blek turns up as one of the parade of odd, one-scene aliens and background figures that populate Futurama's universe — a small presence rather than a driver of plot, defined mostly by voice and manner rather than any stated ambition or history.

Maurice LaMarche is one of animation's great utility voices, and even a glancing role gets his full craft: a distinct cadence, a specific comic weight, a sense that someone thought hard about how this creature sounds. That care is what makes Futurama's crowded margins feel inhabited rather than filler.
