The Best 10 Science Fiction & Fantastical Series of 2025

How would you do if you had boundless power? That's the core inquiry posed by the best sci-fi and fantastical narratives. Imagine if you possessed superhuman abilities? Perhaps discovered a life-altering substance? What about every single person became dedicated to your personal happiness? Would you use that power for the greater good, or would you give in to your own baser instincts?

These series ranked below each explore that very theme in unique manners (aside from one key exclusion). Presented here is a countdown of the ten best seasons of sci-fi and fantasy television from 2025.

10. Your Friendly Neighborhood Spider-Man

Even after more than 60 years of history, the web-slinger continues to be reinvented by fresh talent. This series presents a novel look at the character's formative years, cleverly blending classic source material elements with ideas from other adaptations to craft something that feels both new and profoundly compelling.

Rather than operating alone or having Tony Stark as a mentor, this iteration of the hero develops a complex relationship with the future Green Goblin, who in this story is still just the head of Oscorp. Through their dynamic, Peter grows into a true hero, learning the iconic lesson of great power and great responsibility.

9. Hazbin Hotel Season 2

Creator Vivienne Medrano's boldly transgressive adult musical-comedy show, which sprang from a fan-funded pilot, fully hit its stride in its sophomore installment. Building on the game-changing revelations of season 1, the story expands significantly, following the ambitious TV demon Vox as he takes control of the situation, sparking a chain of ever-more dramatic confrontations that inevitably culminate in elaborate musical numbers.

While it may lack a one breakout song on the level of season one's "Loser, Baby," this is due to each element in this season being more complex. The action, personal development, and especially the music are collectively more sophisticated. The season moves the main plot dramatically while providing plenty of bizarre, wild, and simply entertaining dark fantasy.

8. Daredevil: Born Again

As a successor to the legendary Netflix show, Daredevil: Born Again faced immense shoes to fill. After well-documented development issues, the resulting show proves to be worthy of the effort. The story follows Matt Murdock after his dual life as Daredevil is publicly revealed, leaving him a target to enemies both history and new threats in a slightly version of his well-known setting.

The premiere is a thrilling return to form, evoking the intense tone fans cherished from the prior series. While the middle episodes venture into certain different narrative ground, the season finishes powerfully, setting viewers eagerly anticipating a second season.

7. Common Side Effects

An unexpected this year's gem, this series could be described as a Breaking Bad filtered through the humor of King of the Hill. Helmed by Joe Bennett alongside comedy Steve Hely, it tells the story of a mild-mannered mycologist who discovers a curative mushroom and soon finds himself hunted by forces including ruthless pharmaceutical executives to federal agents.

Despite being a parody, the show plays out with the grave atmosphere of a classic paranoia film. Enhanced by trippy animation and an unnerving score, the plot delves into deeper questions about the mushroom's full effects. It's a smart, visually striking, and utterly compelling first season.

6. Fallout Season 2

The acclaimed series based on the iconic gaming series returned with a new batch of episodes that deepened its epic mystery and broadened its post-apocalyptic world. Although it travels toward the fan-favorite location of New Vegas, the story is not a straight retelling of that game; instead, it further explore ideas of control and freedom.

It skillfully balances several narrative threads and points of view, from Lucy's quest for answers to a knight's reckoning with the dogma of the Brotherhood of Steel. The outcome is a deeply layered and utterly engaging addition to the ever-growing wasteland mythology.

5. Invincible Season 3

This bloody and heartfelt animated series continues its powerful streak in its third outing. The hero faces tremendous pressure on all side: preparing for a coming Viltrumite threat, mentoring his powered sibling, and battling with his secretive GDA. The story once again features some of the most intense fight sequences the series has ever delivered.

Mark's physical and psychological limits are constantly pushed. He must grapple with foes stronger than himself, the consequences of his actions, and the moral burden of his choices. Excellent storylines for key cast members like Cecil Stedman and Rex Splode round out a fantastic season.

4. Peacemaker Season 2

James Gunn's offbeat superhero show came back with increased importance within the revamped DC universe, and it executes on that count. While it successfully lays foundations for future cinematic universe projects, it primarily presents a powerful and self-contained {
