Navigating the vast world of My Hero Academia can be a thrilling experience, but for many fans, the line between essential story progression and optional side content is not always clear. Anime adaptations, especially long-running shonen series, often include episodes that were never part of the original manga. This article focuses on clearly identifying non-canon content within the Summer Camp Arc, more accurately known as the Forest Training Camp Arc, so you can enjoy the story exactly the way you prefer.

What Are Filler Episodes?

Filler episodes are anime-exclusive segments that do not appear in the source material—in this case, Kohei Horikoshi’s manga. Studios produce them primarily to give the original author more time to write new chapters, preventing the anime from catching up too quickly. While some filler is well-received and expands on side characters, it often receives criticism when it breaks pacing or adds events that never impact the larger plot. In My Hero Academia, filler is relatively rare compared to other shonen titles, but it still exists, and knowing where it appears helps viewers maintain a pure, manga-accurate experience if desired.

Defining the Summer Camp Arc (Forest Training Camp Arc)

The Forest Training Camp Arc is one of the most intense and formative periods for Class 1-A. Following the U.A. Sports Festival and the Hero Killer Stain incidents, the students are taken to a secluded woodland facility run by the Wild, Wild Pussycats. Here, they are meant to strengthen their Quirks and prepare for the upcoming Provisional Hero License Exam. The arc is pivotal, setting the stage for the League of Villains’ next major move and delivering critical character development for Bakugo, Midoriya, and several others. It marks a tonal shift from school-centric competitions to genuine life-or-death stakes.

Manga Source and Episode Coverage

In the original manga, the Forest Training Camp Arc spans chapters 70 through 83. The anime adapts this material primarily in Season 3. The canon episodes begin with a cold open that drops viewers directly into the bus ride to the camp. The entire sequence, from arrival at the rest stop to the shocking conclusion, is tightly plotted. Understanding this specific run of episodes is crucial for anyone looking to skip non-essential content or for those who want to read alongside the show.

Canon Episodes of the Forest Training Camp Arc

To experience the arc as Kohei Horikoshi intended, stick to the following episodes. These all derive directly from the manga and advance the main narrative:

  • Episode 40: “Wild, Wild Pussycats” – Class 1-A arrives at the training camp and meets the pro hero team. The brutal strength-building exercises begin.
  • Episode 41: “Kota” – We meet Kota Izumi, the nephew of the Wild, Wild Pussycats, who holds a deep-seated hatred for heroes. Midoriya tries to reach out.
  • Episode 42: “My Hero” – The villain attack commences. Midoriya’s actions lead to a powerful moment that ties back to an earlier promise and changes Kota’s perspective.
  • Episode 43: “Drive It Home, Iron Fist!!!” – The battles in the forest intensify. Class 1-B’s Itsuka Kendo faces off against Mustard, while Tetsutetsu and Kendo work together.
  • Episode 44: “Roaring Upheaval” – The League of Villains’ Vanguard Action Squad puts their plan into full motion, targeting Bakugo directly. The forest becomes a war zone.
  • Episode 45: “What a Twist!” – The class deals with the aftermath of the attack. Bakugo’s capture sets the stage for the next rescue mission, and the students confront their failures.

These six episodes form the complete, uninterrupted canon narrative. Each scene builds on the last, pushing the students’ Quirks to new limits and testing their resolve in ways that classroom training never could.

Non-Canon Content Surrounding the Arc

Filler in My Hero Academia typically takes the form of recap episodes, single-episode side stories, or original animation DVD (OAD) specials. Within the immediate vicinity of the Forest Training Camp Arc, there is one major non-canon episode that viewers often confuse with the arc itself.

Episode 39: “Game Start”

Aired right before “Wild, Wild Pussycats,” Episode 39 is a pure recap. It revisits the key events of the first two seasons, framed as an in-universe television special. There is no new animation beyond transitional scenes, and it contributes nothing to the plot. If you are binge-watching the series solely for the story, you can safely skip it. However, because it bears the episode number immediately preceding the Forest Training Camp Arc, many streaming platforms autoplay into it, causing viewers to believe the camp storyline has begun. This episode is the only true piece of filler directly adjacent to the arc.

Common Misinformation About Later Episodes

Some unofficial filler lists incorrectly categorize episodes from Season 5 as part of the Summer Camp Arc. Episodes such as 88 (“A Season for Encounters”), 89 (“The Great One’s Arrival”), and 90 (“Clash of the Villains”) are frequently misattributed. In reality, these episodes belong to the “My Villain Academia” storyline, which covers the Meta Liberation Army arc. They are fully canonical and adapt manga chapters faithfully. The confusion often arises because the earlier training camp arc is sometimes loosely referred to as a “summer camp,” and viewers may mistakenly extend that label to later camps or retreats. For clarity, only Season 3’s forest setting constitutes the training camp arc.

Why Episodes 39 Is Considered Filler

Recap episodes do not move the story forward. They exist to refresh the audience’s memory after a long hiatus between seasons. Studio Bones produced Episode 39 as a bridge between the end of Season 2 and the intense start of Season 3. While it does feature the characters commenting on their own past adventures, it holds no narrative weight. The original manga never included a chapter dedicated to looking back at the Sports Festival or the Stain arc in this manner. Skipping it prevents an artificial pause in momentum as you launch into the high-stakes training camp.

How to Watch the Forest Training Camp Arc Canon-Only

To enjoy the purest adaptation of the manga’s Forest Training Camp Arc, follow this simple watching order:

  1. Complete My Hero Academia Season 2, ending with Episode 38 (“Encounter”).
  2. Skip Episode 39 entirely.
  3. Start Season 3 directly at Episode 40 and watch consecutively through Episode 45.
  4. Continue with the “Hideout Raid” episodes (46 onward) without any further filler breaks.

This path ensures you experience the same tightly paced storytelling that made the manga chapters so gripping. There are no side quests, no original characters woven into the main plot, and no diversions from the central threat of the Vanguard Action Squad.

The Purpose of Non-Canon Material in My Hero Academia

Even though filler can frustrate story-focused fans, it serves practical functions. Beyond giving the manga creator more breathing room, filler episodes can explore character dynamics that the main plot overlooks. For example, the OAD episodes “Training of the Dead” and “All Might: Rising” (usually considered separate from the main series) provide additional backstory and light-hearted moments. Studio Bones has generally respected the source material, keeping filler to a minimum compared to contemporaries like Naruto or Bleach. This restraint means that almost every numbered episode of the main series outside recaps and a handful of originals is faithfully adapted.

Recap vs. True Filler

My Hero Academia uses recap episodes more often than narrative filler. In addition to Episode 39, Episode 64.5 (“Get a Grip on U.A. High’s Super Difficult Curriculum”) and Episode 52.5 (“Prepare for the Provisional License Exam”) also recap past events. None of these are part of the Forest Training Camp Arc, but they appear later in the series. Understanding this distinction helps you avoid mistakenly labeling canon content as filler. True narrative filler—where entirely new, non-canon stories are told—is limited to a very small set of episodes, such as Episode 32 (“Everyone’s Internships”) and Episode 58 (“Special Episode: Save the World with Love!”). The Forest Training Camp Arc remains untouched by such inventions.

Character Development Unique to the Canon Arc

One of the strongest arguments for watching the arc without filler interruptions is the concentrated character work. The Forest Training Camp Arc delivers pivotal moments that define the rest of the series:

  • Bakugo’s Vulnerability: The kidnapping forces Bakugo to confront his own image and the fact that villains see potential in him. His capture is the catalyst for his long-term growth and eventual remorse.
  • Midoriya’s Instincts: Saving Kota is a direct callback to All Might’s philosophy. The act of heroism without thinking solidifies Midoriya’s core identity.
  • Class 1-A’s Teamwork: The students’ ability to coordinate despite the chaos—Todoroki’s ice countering the gas, Shoji’s search abilities, Jiro’s earphone jacks—demonstrates how far they have come since the entrance exam.
  • The League’s Brutality: Villains like Muscular show a level of sadistic violence rarely seen before. This arc shatters any illusion that the students are in a protected school environment.

Splicing in a recap or any standalone filler would undercut this momentum. The arc’s strength lies in its relentless pacing, and the anime adaptation preserves that excellently when watched without the preceding recap.
