He only made a brief appearance and he had no speaking lines, except for being heard sadly crooning as he left the scene. He was seen looking very sad at the party for some reason and Rick tried to get Morty to talk to him, possibly to cheer him up, but Morty stopped him because the last time he did that, it was with Gearhead which turned out to be a disaster. So, when Morty ignored him, he started a conversation with Rick, and so Scropon just walked away, sadly and on the verge of tears. According to Rick, his entire planet was destroyed. He is not seen again for the rest of the episode, which implies that he either spent the rest of the party mourning over his planet or left the party early while in depression.
He made another brief appearance in the episode The Wedding Squanchers as a background character, attending the wedding of Birdperson and Tammy. He was seen among other aliens laughing with Beth. His joy in this episode may imply that he was able to overcome his feelings of sadness and move on from what happened to his planet. Unfortunately Tammy betrays Scropon at the wedding when she reveals herself to be a deep cover agent for the Galactic Federation and proceeded to murder Birdperson, which causes a shootout. During the massacre, Scropon gets shot in the left shoulder by a gromflomite soldier and collapses back first on the floor.
As of now it is unknown whether Scropon survived the massacre or not. However, it is shown that Scropon was lying face down on his stomach with his left arm stretched out and not moving after Squanchy transforms into a hulking monster to try to take down Tammy, which is strange as he was shot at the front side and landed on his back first, which strongly suggests that he was crawling around offscreen until falling unconscious. Other evidence supporting the theory that he survived was that since he was a crustacean like alien and had a hard shell, the shell protected him from some of the impact from the gunshot and given that he also has a top heavy physique, he may have a good amount of blood supply
Given all of this combined with where he was shot, it is heavily implied that he survived the massacre but was somehow arrested by the Federation for unknown reasons with it most likely being a rebel against the federation. He may have been freed from imprisonment after the Federation's collapse in The Rickshank Rickdemption
Not much is known about Scropon's personality as he was not seen as much in the series. In his debut episode, he was revealed to be in severe grief because his home planet was destroyed by unknown circumstances. He seems to hate hearing the word "destroyed" a lot as he growled sadly when Morty said it.
As he was seen shooting at the federation soldiers at the wedding shootout before getting shot, it is heavily implied that he hates the Galactic Federation with the reason for that being that they were allegedly the ones responsible for destroying his home planet simply because his species refused to join the federation given the Federation's militaristic and imperialist behavior.
Despite his monstrous appearance, Scropon appears to be a friendly and easy going guy as he was shown to be good friends with Rick and had a good time socializing with Beth at the wedding.
- The Wedding Squanchers (Non-Speaking Cameo)
- The name of Scropon's species and the name of his home planet is unknown
- While its unknown who or what caused Scropon's home planet to be destroyed, it is possible that it was destroyed by Klargon death squads or by the Galactic Federation. It is very likely that the Galactic Federation was responsible for the destruction of Scropon's home planet giving the Federation is militaristic in structure and Scropon was seen shooting at their soldiers at the wedding massacre, which further suggests that he wants revenge on the Federation.
- Other suspects who could have been responsible for the destruction of Scropon's home planet are the Cromulons, Worldender, and The Vindicators. If the theory of the Vindicators destroying Scropon's home planet is true then his home planet may be Dori
- He is the only friend of Rick's who so far has had no speaking lines and no major role in an episode.
- Scropon's name is an anagram of the word "Scorpion" but the letter I is not in his name
- The Art Of Rick And Morty revealed that Scropon was originally going to have a scropion tail as seen in an early design of him but the tail did not make the final design.
