Our Best 10 Sci-Fi & Fantasy Series of 2025
What could you accomplish with infinite control? That's the fundamental question asked by all finest sci-fi as well as fantastical narratives. Imagine if you were granted extraordinary powers? Or discovered a life-altering substance? Or if each and every other human became dedicated to your personal happiness? Would you use that power for the greater good, or would you succumb to your own baser impulses?
The shows featured below each grapple with this theme in distinct ways (aside from one notable exception). Outlined below is a list of the ten most outstanding seasons of science fiction & fantastical television from the past year.
10. Your Friendly Neighborhood Spider-Man
Despite more than six decades of stories, Spider-Man remains reinvented by fresh creative voices. Your Friendly Neighborhood Spider-Man delivers a refreshing look at the hero's formative years, skillfully combining classic source material story beats with influences from other adaptations to craft something which is simultaneously new and profoundly engaging.
Instead of operating alone or Tony Stark as a mentor, this iteration of Peter Parker develops a evolving partnership with Norman Osborn, who here is still just the head of Oscorp. Through their dynamic, Peter becomes a true hero, learning the signature lesson of power and great responsibility.
9. Hazbin Hotel Season 2
Creator Vivienne Medrano's boldly transgressive mature musical series, which sprang from a crowdfunded short, fully came into its own in its second season. Building on the climactic revelations of the first season, the story expands significantly, following the scheming media overlord Vox who takes control of the situation, igniting a chain of increasingly explosive confrontations that naturally culminate in elaborate musical numbers.
While it may lack a single viral hit on the level of season one's "iconic tune," this is due to each element in season 2 being more complex. The action, personal arcs, and especially the score and songs are collectively elevated. The story advances the main storyline dramatically while delivering no shortage of bizarre, wild, and ultimately entertaining dark fantasy.
8. Daredevil: Born Again
As a successor to the acclaimed Netflix show, this series had enormous expectations. After significant production challenges, the final product demonstrates it was worthy of the wait. The plot centers on Matt Murdock after his secret identity as Daredevil is exposed, leaving him vulnerable to foes both past and new threats in a refreshed version of his familiar world.
The first episode is a thrilling return to form, capturing the intense tone audiences cherished from the prior incarnation. Although the subsequent chapters venture into some new territory, the season concludes powerfully, setting viewers eagerly awaiting a second season.
7. Common Side Effects
A surprising 2025 gem, this series is essentially an animated crime saga with a humor of a suburban satire. Helmed by Joe Bennett alongside writer Steve Hely, it tells the saga of a mild-mannered mycologist who finds a miraculous mushroom and quickly finds himself pursued by everyone from unscrupulous Big Pharma executives to government agents.
Far from being a spoof, the show plays out with the serious atmosphere of a 1970s paranoia thriller. Enhanced by trippy animation and an unnerving score, the plot explores bigger questions about the mushroom's true effects. It's a intelligent, beautifully animated, and completely gripping first season.
6. Fallout Season 2
The acclaimed adaptation of the iconic video game series returned with a new batch of episodes that expanded its sprawling lore and expanded its post-apocalyptic world. While it travels toward the legendary location of New Vegas, the season is not a direct adaptation of that title; rather, it continues to explore ideas of authority and freedom.
It expertly juggles multiple narrative threads and points of view, from Lucy's mission for answers to Maximus's struggle with the ideology of the Brotherhood of Steel. The result is a deeply detailed and wholly absorbing addition to the ever-growing wasteland saga.
5. Invincible Season 3
The visceral and emotionally charged adult animation show keeps its winning momentum in season 3. The hero faces immense challenges on all fronts: training for a looming Viltrumite invasion, mentoring his young brother, and battling with his shadowy GDA. The story also features some of the most intense fight scenes the series has yet delivered.
The protagonist's bodily and emotional endurance are repeatedly tested. He must contend with opponents stronger than he is, the consequences of his battles, and the ethical burden of his choices. Standout arcs for supporting characters like Cecil Stedman and Rex Splode complete a superb season.
4. Peacemaker Season 2
James Gunn's offbeat superhero show came back with elevated importance within the new DC canon, and season 2 executes on that fronts. Although it effectively lays foundations for future cinematic universe projects, it also presents a powerful and focused {
