The Best 10 Science Fiction and Fantasy Series of 2025

How would you do if you had infinite power? That's the fundamental question asked by the greatest sci-fi and fantastical tales. Imagine if you were granted extraordinary powers? Perhaps discovered a miraculous substance? Or if each and every other human became wholly committed to your happiness? Could you wield such influence for good, or would you give in to your own darker instincts?

The television series ranked herein all confront this concept in various ways (with a single notable exclusion). Detailed here is our countdown of the ten top seasons of science fiction and fantasy television from the past year.

10. Your Friendly Neighborhood Spider-Man

Even after over 60 years of stories, Spider-Man continues to be reimagined by new creative voices. Your Friendly Neighborhood Spider-Man delivers a refreshing perspective at the character's early years, skillfully merging classic source material elements with influences from the broader Marvel universe to create something that feels both fresh and profoundly compelling.

Instead of operating solo or having Iron Man as a guide, this version of the hero forges a complex relationship with the future Green Goblin, who in this story is still just the head of Oscorp. Through their dynamic, Peter becomes his own man, internalizing the signature lesson of great power and responsibility.

9. Hazbin Hotel Season 2

Showrunner Vivienne Medrano's audacious adult musical-comedy show, which originated as a fan-funded short, truly came into its own in its sophomore season. Following the climactic revelations of the first season, the narrative broadens considerably, centering on the ambitious TV demon Vox who seizes command of the narrative, sparking a chain of ever-more dramatic conflicts that inevitably culminate in elaborate musical numbers.

While it might not have a single viral song on the level of season one's "Loser, Baby," this is due to everything in this season being more complex. The action, personal development, and especially the score and songs are collectively more sophisticated. The season moves the overarching plot dramatically while providing plenty of bizarre, unhinged, and simply fun fantasy.

8. Daredevil: Born Again

As a successor to the acclaimed Netflix series, this series faced immense shoes to fill. Despite significant production issues, the resulting product demonstrates it was worthy of the effort. The story centers on Matt Murdock after his secret identity as Daredevil is publicly revealed, leaving him vulnerable to foes both past and present in a refreshed take of his familiar world.

The first episode is a thrilling return to form, capturing the intense feeling audiences loved from the prior series. Although the middle episodes venture into certain new territory, the first season concludes on a strong note, leaving fans eagerly awaiting a second season.

7. Common Side Effects

An surprising 2025 highlight, this series is essentially a Breaking Bad filtered through a sensibility of a suburban satire. Helmed by an Adult Swim veteran and writer Steve Hely, it tells the saga of a mild-mannered fungi expert who discovers a miraculous mushroom and soon finds himself pursued by everyone from unscrupulous pharmaceutical CEOs to federal authorities.

Far from being a parody, the show unfolds with the grave atmosphere of a classic paranoia thriller. Accentuated by hallucinogenic animation and an unnerving score, the plot delves into bigger mysteries about the substance's true effects. It's a intelligent, visually striking, and utterly compelling ten-episode season.

6. Fallout Season 2

This hit series of the iconic video game franchise came back with a second batch of stories that expanded its sprawling mystery and expanded its nuclear wasteland setting. While it travels toward the fan-favorite location of New Vegas, the season is far from a direct adaptation of that title; rather, it continues to explore themes of authority and autonomy.

It expertly juggles several storylines and points of view, from Lucy's mission for answers to Maximus's reckoning with the dogma of the Brotherhood of Steel. The result is a rich detailed and utterly engaging addition to the expanding Fallout saga.

5. Invincible Season 3

This visceral and heartfelt animated series continues its powerful momentum in season 3. Mark Grayson confronts tremendous pressure on all fronts: training for a looming alien invasion, mentoring his young brother, and clashing with his shadowy GDA. The season also includes some of the most brutal action scenes the series has ever delivered.

Mark's bodily and emotional limits are repeatedly pushed. He must contend with foes more powerful than himself, the consequences of his actions, and the ethical burden of his decisions. Excellent arcs for key cast members such as Cecil Stedman and Rex Splode round out a fantastic season.

4. Peacemaker Season 2

James Gunn's irreverent anti-hero series came back with elevated importance within the revamped DC universe, and it executes on both count. While it effectively lays groundwork for upcoming cinematic universe stories, it also presents a powerful and self-contained {
