- “Say hi to Francisco Franco.”
- —Fascism-fighting Morty to Morty C-137[src]
This Morty looked pretty much identical to most other Mortys before he started his fascism-crushing crusade. By the time he met Rick and Morty from C-137, he had bags under his eyes, scruffy hair, a bruise on his right chin and wore a bloodied shirt.
At some point, most likely due some reason to his grandfather Rick, Morty became obsessed with stopping fascism at all cost. He got himself a "Hitler-measuring gun" from his grandfather, which he took along with a portal gun and a Laser gun. From then on, he went from dimension to dimension, fighting and killing everyone who measured high on the "Hitler-measuring gun".
In one dimension he met his C-137 counterpart doing the exact same thing. They both scanned each other and prepared to shoot, but Rick C-137 shot this Morty first. This Morty's death led Morty C-137 to end his crusade and return home.
