What middle initial is given for Rick Sanchez? The answer is D.
Rick Sanchez is commonly identified as Richard D. “Rick” Sanchez, making D. the middle initial given for the character. He is the eccentric scientist at the center of Rick and Morty and the grandfather who repeatedly pulls Morty into dangerous interdimensional adventures.
The initial appears in character references and is easy to overlook because the series almost always calls him Rick Sanchez. The character’s identity is also complicated by the show’s multiverse: numerous versions of Rick exist, while the principal Rick is strongly associated with Dimension C-137.
Rick’s formal name is not usually used in everyday dialogue, unlike his nickname. That helps explain why viewers may remember only “Rick Sanchez” or mistake the initial for part of a dimension designation. C-137 identifies the Rick most closely followed by the story; it is not his middle initial or a conventional part of his personal name.
The D. therefore belongs to his given-name format, while C-137 belongs to the show’s parallel-universe numbering system.
