Rubio soon moved on to Chilling Adventures of Sabrina, joining the series as one of the main antagonists in season 3. Rubio plays a character named Nagaina, a pagan god who visits Greendale as part of a traveling carnival. Nagaina, along with Pan (Will Swenson), leads the pagans in their effort to find a sacrifice and resurrect the Green Man, the oldest of the pagan gods.
It's clear that Rubio has a talent for playing morally ambiguous or sinister characters, and she shines in Chilling Adventures of Sabrina as the slithery Nagaina. Her character is a gorgon, like the more well-known Medusa, who can turn people to stone by sharing their gaze. In particular, Nagaina causes trouble for Sabrina (Kiernan Shipka) and her friends when she turns Roz (Jaz Sinclair) to stone so that she cannot use her Cunning ability to stop the pagans. Sadly, Rubio's character does not survive Sabrina's plan to save everyone and stop the Green Man from rising, and she ends up with the same fate as her gorgon-sister Medusa.
Although Rubio joined Cobra Kai before it jumped to Netflix, it seems like it was fate that she would end up in another project for the streamer. Even better, Cobra Kai season 4 is already in the works, and Rubio is sure to return as Carmen. Netflix obviously likes the actress and considers her for many of their projects, so fans can hope that there's more of Rubio to come in the future.
