There is one axiomatic truth about Rick and Morty: It's absolutely insane. The infinite parallel universes that the infinite Ricks and Mortys explore open up infinite possibilities for... well, anything. Coinciding with this truth is the countless Rick and Morty fan theories circulating on the web. One such mind-boggling theory argues that this Morty isn't Rick's original Morty. Confusing as it may sound, it's an idea that actually carries a lot of wait.
Given that Rick and Morty have replaced at least one pair of their dead counterparts early in the series, it's not at all implausible that the two aren't an original pair. Any number of crazy adventures could have resulted in this Cartoon Network dream team splitting up and reassembling.
Read on to discover all you need to know about this original Morty fan theory. As a bit of deep dive, this article obviously contains by a fair bit of spoilers – so don't be such a Jerry.
Rick identifies himself numerous times as haling from Dimension C-137, and the second season episode "Mortynight Run" offers written proof of this. While dropping Jerry off at the extraterrestrial daycare for Jerrys (aptly named "Jerryboree"), audiences get a glimpse at a sign-in sheet that corroborates Rick's claim.
The licensed mobile game Pocket Mortys claims the current Morty hails from Dimension C-145. If the title is considered canon, this offers conclusive proof that he's not C-137 Rick's original Morty.
However, the television series itself also offers plenty Morty isn't Rick's original.
It isn't actually stated in the show, but Rick's two-decade long absence is documented the series's description: "After missing for nearly 20 years, Rick Sanchez (Justin Roiland) suddenly arrives at his daughter Beth’s (Sarah Chalke) doorstep looking to move in with her and her family."
On two separate occasions, audiences are given proof of Rick being present during Morty's infancy. In "Close Rick-counters of the Rick Kind," Rick is subjected to a machine that shows him his own memories, and there are images of him with baby Morty.
Also, in "Get Schwifty," there are images of Rick holding infant Morty in Bird Person's house. But if Rick was gone for 20 years and Morty is truly only 14, there shouldn't be any images of two together at this time... unless these images feature a different Morty.
