There are many memorable Rick and Morty characters, but there's something special and unique about Unity, a minor character who left a big impression. The animated sitcom may revolve around scientist Rick and Rick's grandson Morty, but other characters are important parts of their quirky lives. Rick and Morty is known for having celebrity guest stars, from Nathan Fillion to Jordan Peele, Keegan Michael-Key, Alfred Molina, and John Oliver. Christina Hendricks voiced Unity on Rick and Morty and they remain one of the more engaging smaller characters.
