Kid #2

Kid #2 is exactly what the credit implies: an unnamed child glimpsed in the crowd scenes of a future New New York, one voice among the background chatter that makes Futurama's world feel populated rather than empty. No arc, no name, just a passing moment of city noise.

The joke of a show stacking its universe with throwaway roles like this is that veteran voice actors pour real craft into thirty seconds of dialogue nobody will remember. Tress MacNeille, a Simpsons-level utility player, brings the same commitment to Kid #2 that she'd bring to a lead, and that generosity is part of why the background of this show feels so alive.
