'Common Side Effects' Returns For Season 2 On Adult Swim

Fans of the hit animated thriller *Common Side Effects* finally know when the show is making its high-stakes return. Co-creators Joe Bennett and Steve Hely took the stage during a panel at New York Comic Con to deliver the news directly to audiences, revealing that the critically acclaimed series will kick off its second season on Adult Swim, with next-day streaming available on HBO Max. The network confirmed the highly anticipated second chapter is scheduled to premiere on Jan. 24, 2027, at 11 p.m. ET/PT.

The show earned an Emmy nomination and an Independent Spirit Award nod, while securing a prestigious Peabody Award and four Annie Awards.

The high-concept animated narrative follows Marshall, voiced by Dave King, a gifted fungi researcher who makes a groundbreaking discovery. Marshall uncovers a rare mushroom species nicknamed the Blue Angel, which holds the astounding ability to cure virtually any illness known to humanity. However, his idealistic goal of releasing this medical breakthrough to the public quickly turns into a nightmare. Rather than celebrating his discovery, Marshall finds himself thrust into extreme danger. A massive pharmaceutical empire, the U.S. government, and the Drug Enforcement Administration immediately align to suppress the miracle cure, willing to take extreme measures to prevent the everyday public from ever accessing it.

The upcoming second season picks up with the fallout of that massive conspiracy.

Now classified as wanted fugitives, the duo must outsmart law enforcement and powerful corporate operatives who are determined to permanently silence them. As the hunt intensifies, Marshall and Frances fight to protect the Blue Angel and uncover a way to bring its healing powers to humanity. Audiences can look forward to even more intense suspense and dark political satire when the series makes its triumphant return to the airwaves.
