The Best 10 Sci-Fi & Fantastical TV Shows of 2025

How would you do with unlimited power? That's a core question explored by all greatest science fiction as well as fantasy narratives. What if you were granted extraordinary powers? Perhaps discovered a life-altering substance? What about each and every single person became dedicated to your personal happiness? Could you wield such power for good, or would you succumb to your own darker instincts?

The series listed herein each grapple with this theme in distinct ways (with a single notable exception). Detailed below is a list of the 10 top installments of sci-fi & fantastical television from the past year.

10. Your Friendly Neighborhood Spider-Man

Despite over six decades of stories, the web-slinger is constantly reimagined by new talent. This series delivers a novel look at the hero's early years, skillfully merging essential comic elements with influences from other adaptations to craft something which is both new and deeply compelling.

Instead of being alone or having Iron Man as a guide, this version of the hero develops a complex relationship with the future Green Goblin, who here is still just the CEO of Oscorp. Through their dynamic, Peter grows into his own man, internalizing the signature mantra of great power and responsibility.

9. Hazbin Hotel Season 2

Creator Vivienne Medrano's audacious adult musical show, which originated as a fan-funded short, fully found its footing in its sophomore installment. Building on the climactic revelations of season 1, the narrative expands significantly, centering on the ambitious TV demon Vox as he seizes control of the narrative, sparking a series of increasingly dramatic conflicts that inevitably end in show-stopping song.

While it might not have a single viral song quite like season one's "iconic tune," this is due to each element in this season being increasingly ambitious. The action, personal arcs, and especially the music are collectively elevated. The season advances the overarching plot forward while providing no shortage of bizarre, wild, and ultimately fun dark fantasy.

8. Daredevil: Born Again

As a successor to the acclaimed Netflix show, Daredevil: Born Again had enormous expectations. After well-documented development issues, the resulting show demonstrates to be worth the wait. The plot follows Matt Murdock once his dual life as Daredevil is publicly revealed, making him a target to enemies both past and new threats in a refreshed version of his well-known world.

The premiere is a thrilling return to form, evoking the gritty feeling audiences cherished from the original incarnation. Although the subsequent chapters explore some different narrative ground, the first season concludes on a strong note, setting viewers eagerly anticipating a second installment.

7. Common Side Effects

A unexpected 2025 gem, this series could be described as an animated crime saga filtered through a humor of a suburban satire. Created by an Adult Swim veteran and comedy Steve Hely, the series tells the story of a nerdy fungi expert who discovers a miraculous mushroom and soon finds himself hunted by everyone from unscrupulous Big Pharma executives to federal agents.

Far from being a spoof, the narrative unfolds with the serious atmosphere of a 1970s paranoia film. Enhanced by trippy visuals and an unnerving musical soundtrack, the story explores deeper questions about the mushroom's true effects. It's a smart, visually striking, and completely gripping ten-episode season.

6. Fallout Season 2

The acclaimed series based on the iconic gaming franchise returned with a second batch of episodes that expanded its sprawling lore and expanded its post-apocalyptic world. Although it travels in the direction of the fan-favorite location of New Vegas, the season is far from a straight retelling of that game; instead, it continues to explore themes of authority and autonomy.

It skillfully balances several storylines and perspectives, from Lucy's mission for justice to a knight's struggle with the ideology of the Brotherhood of Steel. The outcome is a deeply layered and wholly engaging addition to the ever-growing wasteland mythology.

5. Invincible Season 3

The visceral and emotionally charged adult animation show keeps its winning momentum in season 3. Mark Grayson confronts immense challenges on every side: preparing for a coming Viltrumite invasion, guiding his young brother, and battling with the secretive GDA. The season once again includes some of the most intense action sequences the show has yet produced.

The protagonist's bodily and psychological endurance are constantly pushed. He must grapple with opponents stronger than himself, the consequences of his battles, and the ethical burden of his choices. Standout storylines for supporting cast members like Cecil Stedman and Rex Splode round out a superb season.

4. Peacemaker Season 2

James Gunn's irreverent superhero show came back with elevated importance within the new DC canon, and it delivers on that count. Although it effectively lays groundwork for future DCU projects, it primarily presents a resonant and focused {
