Additional Voices

"Additional Voices" isn't one character but a credit line — the catch-all for the smaller parts an actor fills in around their main role. Here it covers whatever incidental townsperson, alien extra, or one-line background voice needed filling on a given episode of Rick and Morty, work too brief to name but essential to the show's crowded, chattering universe.

Spencer Grammer already anchors the show as Summer, so these scraps are proof of range rather than necessity — quick, disposable voices dropped into the margins of a script. They matter less as characters than as evidence of how thoroughly a small cast stretches to fill Rick and Morty's endless background noise.
