The upcoming season will consist of eight episodes in total, maintaining the high-stakes storytelling established in previous installments. Following the triple-episode premiere, the series will transition to a traditional weekly release schedule. Each new chapter will drop on the streaming platform every Wednesday, leading up to a highly anticipated season finale scheduled for April 22, 2026.

Voice stars Steven Yeun and J.K. Simmons are expected to continue their roles as the father-son duo Mark and Nolan Grayson. The series remains a crown jewel for Amazon MGM Studios, continuing its exclusive run on the Prime Video platform. With Season 4 now officially on the horizon, viewers can prepare for more of the brutal action and emotional weight that has made this comic book adaptation a global standout.
