Navigating a beloved long-running anime like My Hero Academia brings both excitement and the occasional pacing hurdle. Filler episodes—content created specifically for the anime that doesn’t advance the manga-based main plot—are a reality for many series. While My Hero Academia is often praised for its relatively lean filler count compared to giants like Naruto or Bleach, there are still standalone stories and recap episodes that can disrupt the narrative flow. This guide breaks down exactly which episodes are pure filler, which blend canon with original material, and how to streamline your viewing without missing a beat.

What Are Filler Episodes and Why Do They Exist?

Filler episodes are anime-original segments inserted into the broadcast schedule, typically to prevent the show from overtaking the source manga. Because My Hero Academia’s manga is released weekly (with occasional breaks) and the anime adapts two to three chapters per episode, the studio—Bones—must sometimes pause the core story to maintain a healthy gap. Fillers emerge as interstitial tales: school festivals, training competitions, or character spotlights that don’t appear in Kohei Horikoshi’s pages.

These episodes aren’t inherently bad. A well-crafted filler can enrich the world, deepen relationships, or deliver comedy that pace-heavy arcs lack. However, for viewers focused strictly on Deku’s journey and the League of Villains’ schemes, fillers can feel like detours. Recognizing them helps you make an informed choice about what to watch.

Filler types commonly found in shōnen anime include:

  • Recap Episodes: Summaries of past events, often framed by characters reminiscing. These are the most skippable.
  • Slice-of-Life Standalones: Lighthearted, non-canon adventures that explore daily life at U.A. High School.
  • Mixed Canon-Filler Episodes: Segments of canon plot padded with original scenes to stretch runtime, often subtle.
  • Original Arcs: Multi-episode stories created entirely by the anime team—rare in My Hero Academia, but present in other titles.

Recognizing the difference between pure filler and episodes that merely feel slow is crucial. Some action-heavy episodes adapt canon material but at a deliberate pace; these aren’t filler. The official filler designation applies only to content that doesn’t advance the story mapped out by the manga.

The True Filler Episode List for My Hero Academia

Contrary to some online mislists that flag early episodes like “Start Line” (Episode 4) or “The Test” (Episode 5), the actual filler content in My Hero Academia is minimal. To date, the anime has only a handful of full filler episodes, alongside a few recap specials. Here is the accurate breakdown, organized by season.

Season 1: No Pure Fillers

Season 1 adapts the manga’s first 21 chapters tightly. Every episode from “Izuku Midoriya: Origin” to “In Each of Our Hearts” is canon. Some streaming guides incorrectly label Episode 13 (“The Bizarre Adventure of the Hero Killer: Stain”) or Episode 14 (“The Great Debate”) as filler, but those are integral to the story. Even the U.A. Sports Festival preliminary events are directly from the source material.

Season 2: One Anime-Original Episode

Season 2 introduces the sports festival, hero killer Stain, and final exams. Amidst these arcs, the anime inserted one standalone episode:

  • Episode 32 – “Everyone’s Internships”: This is a full filler episode that retells the events of the sports festival and internship arc through the perspectives of the U.A. teachers as they discuss their students. It adds nothing new to the plot and can be skipped entirely.

Season 3: The Only Pure Filler Arc

Season 3 covers the forest training camp, Kamino Ward battle, and provisional license exam. It also contains the most famous filler episode:

  • Episode 58 – “Special Episode: Save the World with Love!”: An entirely original story set after the license exam. The students participate in a staged villain crisis for a television commercial, leading to comedic and heartfelt interactions. While it’s non-canon, many fans consider it a charming detour. If you’re strictly following the main narrative, you can skip this one.

Season 4: Recap Specials

Season 4 introduces the Shie Hassaikai arc and the school festival. Here, filler comes in the form of recap episodes:

  • Episode 76 – “Infinite 100%” (Special Recap): A summary of the Shie Hassaikai climax up to that point, broadcast before the arc’s finale. It reuses footage and offers no new content.
  • Episode 87 – “Japanese Hero Billboard Chart” (Recap): A recap of the Pro Hero Arc and the start of the Endeavor Agency arc, primarily a clip show.

Both are completely skippable. They were produced to give the animation team additional breathing room for high-action episodes later in the season.

Season 5–7: Recaps and Short Specials

Later seasons maintain the series’ canon-dense approach. Season 5 includes a recap special “Episode 99.5 – ‘Before the Quirk, the Will’” that compiles the Joint Training Arc, and Season 6 periodically inserts mid-season recaps like “Episode 136.5 – ‘A Look Back to the Final Act’.” These are clearly labeled on streaming platforms and can be bypassed. Season 7, as of mid-2024, has continued this pattern with no standalone filler arcs.

It’s important to note that several episodes listed on casual filler sites are not filler. Episodes like “The Test of Courage” (36), “The New Power” (37), “The Scouting Party” (39), and “The Big Showdown” (41) are all canon. They may include extended original scenes, but the core events come directly from the manga. This mixed approach—adding a few minutes of anime-original content to a canon chapter—enhances pacing and character beats without creating filler.

How Filler Affects the Viewing Experience

Skipping filler is not just about saving time; it’s about preserving narrative momentum. My Hero Academia builds its emotional peaks through carefully laid plot threads. Interrupting a multi-episode battle with a flashback recap or a comedic side quest can dilute tension. For binge-watchers, filler can be especially disruptive, making it harder to stay immersed in the stakes.

On the other hand, the series’ limited filler can serve as a breather. Episode 58, for instance, showcases hero society’s media manipulation and gives spotlight to characters like Mount Lady and Midnight in a humorous setting. If you enjoy the cast’s non-action dynamics, these moments can feel rewarding. The decision ultimately hinges on your viewing priorities.

Mixed canon-filler episodes, where a canon scene is extended with original material, are the trickiest to judge. For example, the Provisional License Exam arc includes several episodes that expand upon the students’ individual battles, adapting a single manga chapter across two episodes. While these additions are technically original, they don’t change the outcome and are woven seamlessly into the story. I don’t recommend skipping these, as they often enhance character development that the manga glossed over.

Should You Skip or Watch Filler Episodes?

Your approach depends on what you value most from My Hero Academia:

Reasons to Skip Filler

  • Time sensitivity: With over 150 episodes (and counting), every skip saves roughly 22 minutes. Recap episodes especially waste time for viewers who have just watched the arcs being summarized.
  • Plot cohesion: The main storyline’s internal logic is never dependent on filler events. Characters don’t reference original episodes later; no skills or relationships introduced in filler carry forward.
  • Tone consistency: Some filler, like Episode 58’s commercial shoot, adopts a farcical tone that may clash with the darker arcs surrounding it (the overhaul of the Shie Hassaikai, for instance).

Reasons to Watch Filler

  • Character exploration: Episode 58 gives rare screen time to side characters and explores their personalities outside typical hero work. It can deepen your appreciation for the broader world.
  • Animation showcases: Even filler sometimes features high-quality animation from Bones’s talented staff. The comedy and action choreography can be a visual treat.
  • Community context: Fans often reference filler moments in memes and discussions. Watching them can enrich your participation in the fandom.

Personally, I recommend skipping recap episodes without hesitation and giving the sole pure filler episode (Episode 58) a try unless you’re a strict manga purist. It’s light, fun, and won’t take long to sample.

How to Identify Filler Episodes Accurately

Relying exclusively on a single list can be risky, as inaccuracies abound. Use a combination of these trusted resources to confirm an episode’s status before hitting play:

  • Anime Filler List (animefillerlist.com): A community-maintained database that marks episodes as filler, mixed canon/filler, or manga canon. It’s updated regularly and allows user voting, which catches errors.
  • MyAnimeList episode guide: The episode discussion threads often clarify if an episode is filler. Look for keywords like “anime-original” in the description.
  • Fandom wiki: The My Hero Academia Wiki provides episode summaries and notes whether content is adapted from the manga.
  • Streaming platform markers: Some services, like Crunchyroll, label “recap” episodes directly in the title. If you see “Special Episode” or “Recap,” it’s a red flag for filler.
  • Check original broadcast dates: Filler episodes sometimes air immediately after major canon milestones or right before a season finale to buy the manga time.

A common mistake is assuming any episode that feels slow is filler. The Provisional License Exam, for example, is fully canon but can drag due to its structure. Similarly, the U.A. School Festival arc is entirely canon, yet some viewers mistake its lighter tone for filler. Always cross-reference if you’re uncertain.

A Streamlined Watch Order for Canon Purists

If you want the purest narrative experience, follow this streamlined order:

  1. Watch Season 1 in its entirety (Episodes 1–13).
  2. Watch Season 2 but skip Episode 32 (“Everyone’s Internships”).
  3. Watch Season 3 through Episode 57. Skip Episode 58, then continue from Episode 59.
  4. For Season 4, skip Episode 76 and Episode 87. All other episodes are essential.
  5. In Season 5, skip the recap episode 99.5. The series remains canon from Episode 88 onward.
  6. For Seasons 6 and 7, bypass any mid-season recap specials clearly marked on your platform (e.g., Episode 136.5).

This order cuts out maybe 2 hours of total runtime while preserving every vital plot point. You’ll miss no character development, no foreshadowing for future arcs, and no emotional payoff. If you later decide to revisit the filler, it’s all waiting as a bonus feature.

OVAs, Movies, and Canon Adjacent Content

Beyond weekly episodes, My Hero Academia has released multiple Original Video Animations (OVAs) and theatrical films. Their canonicity varies, and understanding them helps complete the picture.

  • OVA 1 – “Save! Rescue Training!”: Set after the U.A. Sports Festival, this anime-original story is not manga canon but is referenced lightly in a later volume’s omake. It’s usually considered skippable.
  • OVA 2 – “Training of the Dead”: A hilarious zombie-apocalypse simulation involving Class 1-A and some students from Isamu Academy High (characters from Horikoshi’s earlier one-shot). Entirely non-canon but very entertaining.
  • Two Heroes (Movie 1): Takes place between the Final Exams and Forest Training Camp arcs. Horikoshi has said its events align with the series timeline; the movie’s original characters and plot are acknowledged in the manga’s bonus material. While not mandatory, it adds depth to All Might’s past.
  • Heroes Rising (Movie 2): Set after the Meta Liberation Army arc but before the Endeavor Agency arc, this film concludes with a narrative that Horikoshi has confirmed as a thematic “what if” rather than strict canon. Watching it enriches Bakugo and Deku’s dynamic but won’t affect main series understanding.
  • World Heroes’ Mission (Movie 3): Occurs during the Endeavor Agency arc. Completely original and not required viewing.
  • You’re Next (Movie 4): Upcoming; canon status still debated.

These extraneous stories are high-quality productions and feature movie-original characters who sometimes appear in manga side illustrations. I treat them as optional expansions—great if you crave more time with the cast, but entirely safe to skip if you’re only tracking the main plot.

Cultivating a Personal Watch Strategy

Your relationship with filler is a reflection of your commitment to the series. Hardcore manga readers often prefer to skip anything not penned by Horikoshi, while casual anime fans might enjoy the extra content. To make the best decision, ask yourself:

  • Am I planning to catch up quickly for the latest season’s discussions? Skip all filler and recaps.
  • Do I love the slice-of-life moments at U.A. as much as the battles? Watch Episode 58 and the OVAs.
  • Can I tolerate brief anime-original extensions in canon episodes? Then don’t stress over mixed episodes; just enjoy the ride.

My Hero Academia’s filler situation is mercifully simple compared to many of its shōnen peers. With only one true filler episode, a handful of recaps, and a few OVAs, you can control exactly how much extra content you consume. Use this guide as your compass, and you’ll navigate Deku’s journey from quirkless dreamer to top hero with clarity and efficiency.
