However, after working with the series' main Rick directly in "Unmortricken", he acknowledges that Rick C-137 is different from the other Ricks, though he mainly views that as something he could use in the future rather than a virtue. They take the forms of multiple races, genders, and species, and use both male and female avatars around Rick. At the Citadel's Dimensional Drive, Evil Morty also tells Morty that "now [he's] Evil Morty too" when he questions Rick's motives. Unlike other Mortys, Evil Morty speaks in a serious, monotone voice, and lacks a stutter in his speech. Although Campaign Manager Morty tries to reveal Candidate Morty's true identity as Evil Morty to the authorities, he is executed by being ejected into space with the file.

The Citadel has become a self-perpetuating market for Mortys, with Citadel Ricks manipulating events to ensure Jerrys and Beths end up together and creating endless Morty clones from their offspring. He later used this rise to power to fabricate an escape from the Central Finite Curve, destroying almost the entire Citadel and killing countless Ricks and Mortys in the process. Rick opens a portal to leave, but after seeing Evil Morty's smug face realizes that it's a trap; Evil Morty has hacked his portal gun, again.When Morty points out he could just do it anyway, Evil Morty replies that actually using the Omega Device would cause him more headaches when he just wants to be left alone. It was later revealed Evil Rick was merely being controlled by Evil Morty, although he remained undetected and travelled to the Citadel by posing as one of the Mortys liberated from Evil Rick's lair. One day, he grew fed up with his Rick and got him blackout drunk while he engineered a device that would allow him to control Rick, to be hidden underneath a black eyepatch.

Evil Morty expresses disdain for Morty's sell-out nature, but says that it would be pointless to hate him for it; Mortys are "bred" by the Citadel for their forgiveness. Given that Rick was revealed to be the original leader of the Citadel, it is likely he would have that very knowledge. 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. In " Rickmurai Jack" he repeats this, believing and even justifying that Mortys are only bred by Ricks for camouflage and to feel superior, justifying this by showing how Ricks continuously force infinite Jerrys and Beths to be together and create endless Morty clones from their offspring. Unity speaks with Rick through its alien citizens, occasionally switching between avatars mid-conversation.The form mentioned above also appeared in the Rickstaverse game, on a screen inside an abandoned spaceship, with a delete history tab next to it.
