Rick Sheridan Resurfaces in Season 2 of 'Invincible,' but It Has Disturbing Implications

The wait for Season 2 of the acclaimed animated series Invincible is practically a never-ending game. The series first premiered in March 2021 to rave reviews only to undergo a two-year hiatus before the arrival of Season 2 in November 2023. Shortly after its premiere, it went on an unexpected mid-season hiatus. As of March 2024, though, the series is back with the latter half of Season 2 to continue the heroic mayhem on Prime Video.

The streaming series follows Mark Grayson (Steven Yeun), a young man who comes to learn the harsh and violent reality of being a superhero after obtaining his powers. In Season 2, he continues to protect humanity all while struggling with the true nature of his father Omni-Man (J.K. Simmons), who was revealed to have been sent to Earth to begin conquering the planet.

Amid all the superhero drama, a minor character named Rick Sheridan begins to play a larger role in Season 2. What happened to Rick in Invincible? Keep reading to find out.

Rick (portrayed by Jonathan Groff in Season 1 and Luke Macfarlane in Season 2) was first introduced in Season 1. A minor character at first, he is the love interest of William (Andrew Rannells), Mark's best friend. While they initially hit it off during their prospective college visit, Rick is captured by a mad scientist named D.A. Sinclair (Ezra Miller). He subsequently undergoes torturous experimentation and is converted into a cyborg programmed to do Sinclair's bidding.

As Mark attempts to fight him, William is able to help Rick return to his senses, allowing him to work with Mark to defeat Sinclair. Rick is later taken in by the Global Defense Agency (GDA) where he would supposedly receive treatment for his cybernetic body. However, GDA director Cecil Stedman (Walton Goggins) had other plans for him.

What those plans are remains unclear at the moment, but Season 2 offers a terrifying glimpse into what the GDA wants to do with this technology. Rick ends up returning in Season 2, Part 2. Much of his physical form has been restored and he has even started dating William, although he is traumatized by the incident with Sinclaire. However, there's more to him than meets the eye.

GDA agent Donald Ferguson suggests that Rick has been made into an android while in the GDA's care. Donald would certainly know best, as he underwent a similar transformation. In Season 1, Donald is killed by Omni-Man, but is shown to be alive and well in Season 2 with no memory of his own death. As the season progresses, Donald comes to discover that he himself is an android created to resume his duties.

The GDA's own experiments in android development are steadily progressing and look to have concerning implications down the line.
