This is the official Twitter account of Rick & Morty , which has published a picture of Morty and his clones with, clearly, Evil Morty. It is recognizable thanks to its son of robot that fall from the eye. This character is also often fitted with an eye patch how to pirate (or how the Governor in The Walking Dead, your choice).
As a reminder, the following has been elected as president of the Citadel, one of the many dimensions of the series. Not really democrat, it is more like a dictator crazy (he killed all the Rick who were against him during the election in season 3).
The theory (not so crazy) fans
The trick with Evil Morty, is that the fans are more numerous to believe in a theory that had been relayed on Reddit. If this theory is true, then that means that you have seen Evil Morty each episode without you realizing it. And most importantly, it would mean that a huge secret about Rick and Morty would have ensued. In fact, according to many followers of the show animated completely crazy, Evil Morty would actually be the Morty from the universe C-137, one of the heroes, which would then become the villain.
What makes them say that ? In the credits at the beginning of the episodes, there is a scene that recurs in the three seasons, at the very beginning. We see Rick and Morty pursued by monsters. Rick happens to escape into another dimension with his gun that opens portals, but Morty falls and thus remains trapped in the face of the two creatures.

According to several fans, this is what Morty came to C-137, abandoned by his grandfather, which would have made it out of little. Following this experience where he almost died, he would become Evil Morty, renflouant a terrible grudge against his grandfather Rick. This would explain his son’s robotic eye and his anger against the clones of Rick.
