Evil Morty

Evil Morty is a character from the Rick and Morty series.

An evil, eyepatch-wearing Morty that accompanies Evil Rick. He's actually the mastermind behind Evil Rick, controlling him remotely. And later became the leader of Citadel.

Personality
On the surface, Evil Morty appears to be a compassionate, understanding, and calm Morty who believes that the main problem with the Citadel of Ricks is that the main division is between the Ricks and Mortys who are on the top and do whatever they want and the Ricks and Mortys who are average workers even though they have the same IQ and are barely different. It was from that understanding of the Ricks that felt undermined in this society that he managed to actually beat the other Ricks and win the election, despite him being a Morty and, in the eyes of the Ricks, a joke.

But, once he wins the election and meets with the shadow Council of Ricks, his true nature is revealed. In reality, he is a cold, manipulative, cunning, ruthless, highly intelligent, and tyrannical dictator, almost mirroring most Ricks and even exceeding them at times. He shows no hesitation in killing Ricks or even Mortys who don't agree with his ideals and shows delight when he finally has the opportunity to take his plans into action. It's unclear what his motives are, but, given that he changed the Morty school's curriculum, it is possible that he shows some hatred toward being subservient to Ricks.

Evil Morty is also quite the sadist, watching through Evil Rick as hundreds of Mortys suffer in pain creating the large camouflage dome for his base of operations, which shows that, despite speaking about equality for Ricks and Mortys, he is willing to sacrifice and even use versions of himself for his goals.

When Evil Morty was first seen, little was shown about him, but he stated that it is impossible for a Morty to defeat a Rick. In the episode, it was revealed that he was controlling his Rick and it was possibly his idea to capture Mortys in order to hide himself from the Citadel of Ricks. Unlike other Mortys, Evil Morty speaks in a serious, monotone voice, and lacks a stutter in his speech. Evil Morty's ability to control Evil Rick and become a president both show that, in terms of logical intelligence (as opposed to emotional intelligence), he is much smarter than the average Morty.

When Evil Rick noticed Rick C-137 crying over his memories, he taunts him by saying that Ricks do not care about Mortys. Since Evil Morty was controlling Evil Rick, this suggests that Evil Morty believes all Ricks treat their Mortys like disposable and replaceable objects.

Trivia

 * Evil Morty's starring episodes, Close Rick-counters of the Rick Kind and Tales From the Citadel, both end with "For the Damaged Coda" playing in the background as well as the closing credits. The song has thus become Evil Morty's leitmotif.
 * The floating photographs of Evil Morty show the eye patch on the left eye, while the first time he was shown, the eye patch was on the right eye. Similarly, his jacket pocket is on the other side as well. It's uncertain whether this indicates a mirror image (intentional or not) or a Morty from another universe.
 * The nickname, "Evil Morty", was never actually used in the show. Instead, it was given to this Morty by the fans, and the show's staff came to like it.
 * At the end of "Close Rick-Counters of the Rick Kind", Rick C-137 warns his Morty about becoming too smart for his own good, and he defers on explaining that statement to Morty until he is older. This appears to be a veiled reference to Evil Morty going rogue.
 * It is still unclear why Evil Morty wanted the memories of the show's main Rick; the most commonly proposed fan explanation is that he is the real grandson of this particular Rick, and is hence a teenage version of the Morty who appears in those memories. This explanation is supported by a few mentions that Morty C-137 apparently had no direct interactions with the main Rick as a baby or a toddler.
 * Despite seemingly lacking compassion, Evil Morty could be considered an anti-hero instead of an outright villain, as his assertions about Ricks being selfish and "toxic" are proven several times to be correct. It is therefore possible that Evil Morty's more violent attempts at guaranteeing his own presidency stem from him realizing the potential of nearly all Ricks to inadvertently destroy everything and everyone around them permanently, including entire dimensions.
