There’s a moment every anime fan knows intimately: the opening credits begin, a killer riff drops, and suddenly you’re frozen — hand hovering over the skip button, completely unable to press it. Maybe it’s the way the visuals sync perfectly with the beat, or the vocalist hits a note that vibrates somewhere deep in your chest. Whatever it is, anime openings (called OPs in fan circles) have a stranglehold on our dopamine receptors that no other media format can quite replicate. They’re not just intros — they’re emotional promises, hype machines, and sometimes better art than the episodes they precede.
What makes an anime opening transcend the category of “theme song” and ascend to full-on cultural artifact? It’s a cocktail of animation craft, musical timing, lyrical storytelling, and a strange alchemy that happens when all three collide at exactly the right moment. These sequences are often produced by studios pouring disproportionate resources into 90 seconds of footage, knowing that a legendary OP can define a series’ entire identity. Fans rewatch them obsessively, dissect them frame by frame on Reddit, and argue about rankings with the same passion sports fans bring to championship brackets. And honestly? That passion is completely justified.
This is a love letter to the anime openings that don’t just hit — they obliterate. Whether you’re a seasoned veteran who remembers recording Dragon Ball Z off TV, or someone who just finished their first season of Demon Slayer, this one’s for you.
What Makes an Anime Opening Truly GOAT-Worthy
The term GOAT — Greatest Of All Time — gets thrown around a lot in fan communities, but when it applies to anime openings, there’s actually a rough consensus on what earns the title. The best OPs tend to share several DNA strands:
- Musical power: The song has to work as a standalone track, not just background noise.
- Visual storytelling: Great openings tease plot, character dynamics, or themes without spoiling the story.
- Animation quality: Fluid motion, creative cinematography, and memorable imagery that you can picture even years later.
- Emotional resonance: Something intangible — the OP makes you feel before a single line of dialogue is spoken.
- Cultural longevity: Fans are still talking about it, remixing it, and cosplaying it years after the show aired.
When an opening checks all five boxes, it stops being an intro and starts being a piece of art that stands completely on its own.
The Classics That Started the Conversation
No conversation about legendary anime OPs starts anywhere other than the late ’90s and early 2000s golden era. Neon Genesis Evangelion (1995–1996) set an early benchmark with “A Cruel Angel’s Thesis” by Yoko Takahashi — a bubbly, almost cheerful J-pop track layered over abstract imagery that completely belied the show’s existential horror. That contrast was intentional genius. Fans who grew up with it still feel a Pavlovian rush of excitement at the first few notes.
Cowboy Bebop (1998) took a wildly different approach with “Tank!” by the Seatbelts — a jazz-funk instrumental that felt like it had been teleported from a cool 1960s spy film. No lyrics, no conventional anime pop structure, just raw style. It announced immediately that this show was unlike anything else on the air. Similarly, Fullmetal Alchemist: Brotherhood (2009–2010) gave fans four distinct openings across its run, each one tracking the emotional escalation of the story, with “Again” by YUI serving as the iconic first entry.
The Modern Era Monsters: Raising the Bar Even Higher
If the classics laid the foundation, the 2010s and early 2020s built a skyscraper on top of it. Attack on Titan (known in Japan as Shingeki no Kyojin) redefined what an opening could do emotionally. “Guren no Yumiya” by Linked Horizon, which premiered with the show’s first season in 2013, felt less like a theme song and more like a war cry — complete with German-language choral sections that gave it an epic, almost mythological weight. The opening became a global phenomenon, introduced millions of Western fans to the series, and remains one of the most recognized pieces of anime music worldwide.
Demon Slayer: Kimetsu no Yaiba entered the conversation with “Gurenge” by LiSA for its first season in 2019, a track that charted on the Billboard Japan Hot 100 and introduced mainstream audiences to the idea that anime music belonged on global pop charts — not just niche streaming playlists. The animation accompanying it, produced by ufotable, set a visual standard that’s still being chased today.

The Psychology of Why OPs Hit So Hard
Here’s the science-adjacent part that makes anime fans feel validated for their obsession: opening sequences are engineered — consciously or not — to hack your brain’s reward system. When you watch an OP repeatedly at the start of each episode, you’re building a Pavlovian association. The music becomes a trigger for anticipation, excitement, and the specific emotional state the show produces in you. Essentially, the OP becomes inseparable from your memory of the entire series.
There’s also the element of musical familiarity and the “mere exposure effect” — the psychological phenomenon where repeated exposure to a stimulus increases your preference for it. Combined with emotionally charged narrative visuals, anime openings essentially run a masterclass in emotional conditioning. Your brain isn’t just enjoying the music; it’s associating it with characters you care about, plot moments that broke you, and the specific feeling of being completely absorbed in a fictional world. No wonder your brain never sleeps — and dreams prove it — it’s busy replaying “Unravel” from Tokyo Ghoul at 3 a.m.
A Fan-Ranked Shortlist of All-Time Legendary OPs
This is subjective, hotly debated, and intentionally provocative — which is part of the fun. Here’s a shortlist of openings that consistently top community polls and discussions:
| Anime | Opening Title | Artist | Year |
|---|---|---|---|
| Neon Genesis Evangelion | A Cruel Angel’s Thesis | Yoko Takahashi | 1995 |
| Cowboy Bebop | Tank! | The Seatbelts | 1998 |
| Fullmetal Alchemist: Brotherhood | Again | YUI | 2009 |
| Attack on Titan | Guren no Yumiya | Linked Horizon | 2013 |
| Tokyo Ghoul | Unravel | TK from Ling Tosite Sigure | 2014 |
| My Hero Academia | The Day | Porno Graffitti | 2016 |
| Demon Slayer | Gurenge | LiSA | 2019 |
| Jujutsu Kaisen | Kaikai Kitan | Eve | 2020 |
Every single one of these could anchor a separate argument, and every anime fan reading this has already mentally inserted their personal pick that didn’t make the list. That’s exactly how it should be.
Hidden Gems That Deserve Way More Credit
The GOAT conversation tends to cluster around mega-hits, but some of the most technically impressive and emotionally resonant OPs come from shows that didn’t dominate global streaming charts. Mob Psycho 100‘s opening “99” by MOB CHOIR (2016) is a kaleidoscopic, hand-drawn fever dream that showcases animation experimentation rarely seen in mainstream productions. Hunter x Hunter (2011)’s “Departure!” by Yoshihisa Hirano and Masashi Hamauzu has that rare quality of feeling genuinely adventurous — it sounds like the beginning of something legendary, which it absolutely was.
Shows in the isekai genre — where characters are transported to fantasy worlds — also produce surprisingly strong OPs, with Re:ZERO and That Time I Got Reincarnated as a Slime delivering openings that balance spectacle with genuine character warmth.
Why Anime Openings Are a Unique Art Form
No other medium does this quite like anime. Western TV shows use theme songs, sure, but they rarely treat the opening sequence as a piece of storytelling in its own right — something that rewards re-watching after you’ve finished a series and can now catch all the foreshadowing hidden in plain sight. Anime OPs operate on multiple levels simultaneously: as hype generators, emotional primers, lore drops, and standalone musical experiences.
The best ones make you want to be a better fan — to pay closer attention, rewatch earlier episodes with new eyes, and share the opening with someone who hasn’t seen the show yet just to watch their reaction. That’s not a theme song. That’s a gateway drug, and we are all very willing addicts.
The GOAT debate will never truly end, and that’s precisely what makes it so much fun. New openings are being produced right now that could, five years from now, be sitting at the top of community rankings alongside “Tank!” and “Guren no Yumiya.” The artform keeps evolving, the music keeps hitting harder, and anime fans keep refusing to press skip. Long may that stubbornness continue. Now go rewatch your favorite OP — you’ve earned it.
