The long wait between Rick and Morty seasons is almost over. It’s about squanching time. 

Fans have had to be extra patient in waiting for the fourth season of the hit animated series. Since the Season 3 finale aired in Oct. 2017, the show’s creators Justin Roiland and Dan Harmon signed a long term deal with Adult Swim, with the network ordering at least 70 new episodes.  

Nevertheless, those episodes have been slow to materialize. Some of that is due to the show’s incredibly intricate sequences (think of Pickle Rick dicing his way through a mischief of rats) and detailed locations (like the Citadel of Ricks). But it’s also thanks in part to the vivid imagination of Roiland and Harmon, who seem to delight in creating strange and increasingly absurd characters for Rick and Morty to encounter.

Consider Scary Terry, who made his debut all the way back in the show’s second episode. A legally safe parody of Freddie Kruger, Scary Terry is a funny, tossed-off sketch of a character. And yet by the end of the episode, we’ve met his family and infant son, Scary Brandon, and learn that his insecurities are rooted in a bad experience in catchphrase class. For a guy with swords for fingers, he’s a deep and multifaceted character.

The Rick and Morty universe is populated with supporting characters like this. Here’s a look at 10 of our other favorites.
