Our Best 10 Science Fiction & Fantastical Series of 2025
How could you accomplish if you had boundless control? This is the core inquiry posed by the greatest science fiction as well as fantastical tales. What if you possessed superhuman abilities? Or stumbled upon a revolutionary substance? What about every other human became dedicated to your satisfaction? Would you use that influence for the greater good, or would you give in to your baser impulses?
The series featured below each confront this dilemma in various ways (aside from a single notable exclusion). Presented here is our list of the ten best installments of science fiction and fantastical television from 2025.
10. Spider-Man: Your Friendly Neighborhood
Despite more than 60 years of history, the web-slinger remains reinvented by new talent. This series offers a novel perspective at the hero's early years, cleverly combining essential comic elements with ideas from the broader Marvel universe to craft something which is simultaneously new and deeply engaging.
Instead of operating solo or Tony Stark as a guide, this version of Peter Parker forges a complex relationship with the future Green Goblin, who in this story is still just the head of Oscorp. Through their interactions, Peter becomes his own man, internalizing the iconic mantra of great power and great responsibility.
9. Hazbin Hotel Season 2
Showrunner Vivienne Medrano's audacious adult musical show, which originated as a fan-funded short, fully found its footing in its sophomore season. Following the game-changing revelations of season 1, the story expands considerably, following the scheming media overlord Vox who takes command of the narrative, igniting a series of ever-more explosive conflicts that inevitably end in elaborate musical numbers.
Although it might not have a one breakout hit quite like season one's "Loser, Baby," this is due to everything in season 2 being more ambitious. The action, character development, and above all the music are collectively more sophisticated. The story advances the overarching plot forward while delivering plenty of bizarre, unhinged, and simply entertaining fantasy.
8. Daredevil: Born Again
As a successor to the legendary Netflix series, this series faced immense shoes to fill. After well-documented development issues, the resulting product demonstrates to be worthy of the effort. The plot centers on Matt Murdock after his dual life as Daredevil is publicly revealed, leaving him vulnerable to foes both past and present in a refreshed version of his familiar world.
The first episode is a thrilling return to form, capturing the gritty tone audiences cherished from the prior incarnation. Although the middle episodes venture into certain different narrative ground, the first season finishes powerfully, setting viewers eagerly awaiting a follow-up season.
7. Common Side Effects
A surprising this year's highlight, this series could be described as a crime saga filtered through a sensibility of King of the Hill. Helmed by an Adult Swim veteran alongside writer Steve Hely, the series tells the saga of a mild-mannered fungi expert who discovers a miraculous fungus and quickly finds himself hunted by everyone from unscrupulous pharmaceutical executives to federal agents.
Despite being a spoof, the narrative unfolds with the grave atmosphere of a 1970s paranoia thriller. Accentuated by hallucinogenic visuals and an unnerving score, the plot explores deeper mysteries about the mushroom's full capabilities. It's a intelligent, beautifully animated, and completely gripping ten-episode season.
6. Fallout Season 2
The acclaimed adaptation based on the popular gaming franchise came back with a new batch of episodes that deepened its epic lore and broadened its post-apocalyptic setting. Although it ventures toward the legendary location of New Vegas, the season is not a straight adaptation of that title; instead, it continues to explore themes of authority and autonomy.
The show skillfully juggles multiple storylines and points of view, from the protagonist's mission for justice to a knight's struggle with the dogma of the Brotherhood of Steel. The result is a rich layered and wholly absorbing addition to the expanding wasteland mythology.
5. Invincible Season 3
This bloody and heartfelt adult animation series continues its powerful momentum in season 3. Mark Grayson faces tremendous pressure on every side: training for a looming Viltrumite threat, mentoring his powered brother, and battling with his secretive Global Defense Agency. The story once again includes some of the most brutal fight scenes the show has yet delivered.
The protagonist's bodily and psychological endurance are repeatedly tested. He must grapple with foes more powerful than he is, the aftermath of his actions, and the ethical weight of his decisions. Standout storylines for key cast members such as Cecil Stedman and Rex Splode complete a superb installment.
4. Peacemaker Season 2
James Gunn's irreverent superhero show came back with increased significance within the new DC universe, and season 2 delivers on that fronts. Although it effectively lays groundwork for future cinematic universe projects, it primarily tells a resonant and focused {
