Scropon

Scropon is an inhuman friend of Rick's he appeared in the episode Ricksy Business. He only made a cameo 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, knowing that it was all over for him.According to Rick, his entire planet was destroyed.
