Top 15 Most Legendary Anime Openings

 

Do you know that feeling when the opening starts, and within 10 seconds, you already know you're going to binge-watch 3 episodes? Anime openings aren't "just" theme songs: they're mini-clips that summarize a series' vibe, announce an arc, and sometimes become even more iconic than the episode itself. Between unforgettable refrains, super stylish montages, and songs that instantly trigger nostalgia, some openings have become true monuments of pop culture.

In this article, we're giving you a Top 15 of the most legendary openings. Whether you prefer "hype" shōnen, a dark atmosphere, or timeless classics, you're bound to find at least one theme song that makes you want to restart the playlist.


1) “A Cruel Angel’s Thesis” - Neon Genesis Evangelion

In Evangelion, you're initially sold a simple premise: teenagers in giant robots, monsters to defeat, a mysterious organization pulling the strings. But very quickly, it deviates: it's no longer just a war against the "Angels"; it's an internal war. Between pressure, solitude, trauma, and symbols everywhere, the series makes you understand that the real battlefield is in the characters' minds.

The opening works precisely because of this discrepancy: a bright, almost "heroic" pop song set to images that sow doubt and discomfort. You sense that behind the energy, there's something heavy... and that immediately intrigues you.


2) “Tank!” - Cowboy Bebop

Here, you follow a band of bounty hunters who cruise through space like hitting jazz bars at 3 AM. Each episode has a different vibe: sometimes comedy, sometimes noir, sometimes drama. And amidst the action, Bebop subtly weaves in moments of melancholy, as if the characters are always chasing something they'll never catch.

The opening, on the other hand, throws its calling card right in your face: big band jazz, sharp rhythm, cinematic graphic editing. Even before the first dialogue, you get the series' complete identity.


3) “GO!!!” - Naruto (Opening 4)

Naruto is the story of a loud kid everyone looks down on, but who refuses to remain "the lonely kid at the back of the class." He wants to become Hokage, not just for prestige, but to be recognized. Between training, missions, forming bonds, and intensifying rivalries, you watch him grow through failures and determination.

This opening is made for that: an energy that pushes you forward, a chorus that tastes of progress, and images that remind you why you became attached to this group.


4) “The World” - Death Note (Opening 1)

Death Note begins like a forbidden fantasy: "what if I had the power to judge the world?" Light finds a notebook that kills, and instead of panicking, he thinks... then he plans. Very quickly, it becomes a giant chess game: one genius against another, traps, counter-traps, and a question that sticks in your mind: at what point does justice become madness?

The opening sets this feeling of moral danger: dark music, almost unsettling images, and an atmosphere that clearly tells you "here, no one is truly safe — not even in their own head."


5) “Again” - Fullmetal Alchemist: Brotherhood (Opening 1)

Two brothers want to bring their mother back. They attempt the forbidden, and life makes them pay dearly: one loses his body, the other sacrifices an arm and a leg. So they hit the road, with alchemy as their tool and guilt as their driving force, searching for a way to fix the impossible... all while discovering that the entire country is built upon something much darker.

The opening successfully summarizes this with emotion: a song that sounds both nostalgic and combative, and editing that puts you in the mood of "we bear our mistakes, but we move forward."


6) “Guren no Yumiya” - Attack on Titan (Opening 1, Season 1)

Imagine a world where humanity has retreated behind giant walls, as if the outside definitively belonged to monsters. Titans aren't just a threat: they're a daily fear, a physical limit to freedom. When the wall cracks, everything changes: survival becomes a war, and revenge a fuel.

The opening, meanwhile, turns you into a soldier in 90 seconds: choirs, epic build-up, martial rhythm. It gets you on your feet, ready to run, as if the alarm has already sounded.


7) “We Are!” - One Piece (Opening 1)

One Piece is a promise of freedom. Luffy doesn't go to sea to "become important"; he goes because his dream is bigger than fear. He recruits a crew, encounters islands each with their own rules, injustices, legends... and transforms each adventure into a declaration of friendship and willpower.

The opening gives you exactly that feeling: open air, optimism, a desire to set sail. It's an opening that puts the wind in your sails.


8) “Cha-La Head-Cha-La” - Dragon Ball Z (Opening 1)

In DBZ, problems aren't solved with a debate: they're solved with training, a transformation, and an even more violent enemy right afterward. Goku and his friends protect Earth, then the universe, then the power dimensions themselves — and yet, the spirit remains surprisingly joyful: they fight because they love to surpass themselves.

This opening is the essence of that: an indestructible chorus, an "anything is possible" energy, and a vibe that makes you want to shout the title at the top of your lungs.


9) “Sono Chi no Sadame” - JoJo’s Bizarre Adventure (Part 1)

JoJo is a family saga where everything is grander, more dramatic, more stylish. It begins with a toxic rivalry between Jonathan Joestar and Dio Brando, a strange artifact, and a destiny that clings to the name "Joestar" generation after generation. The series embraces the theatrical, the tragic, and exaggeration as its signature.

The opening plays this card to the fullest: epic singing, heroic staging, iconic poses. You immediately understand that you're not watching a "normal" anime.


10) “Gurenge” - Demon Slayer (Opening 1, Season 1)

Tanjiro returns home to find his life shattered. He has only one goal left: protect his sister, understand what happened, and fight in a world where demons actually exist. Between training, battles, and tragic encounters, the series blends violence, beauty, and humanity (even among some enemies).

The opening accompanies this journey like a surge of courage: it starts tense, then opens up into pure determination. The sound and visuals put you in the emotional state of "I will endure, no matter what."


11) “unravel” - Tokyo Ghoul (Opening 1, Season 1)

Tokyo has its rules... and its predators. Ghouls live hidden among humans, and Kaneki accidentally crosses to the wrong side. Suddenly, he has to learn to survive with a hunger he never wanted, all while trying not to lose what's left of him. It's a story of identity, fear, and a boundary that is cracking.

The opening doesn't tell: it makes you feel. The fragile voice, the emotional explosion, the unstable images... everything puts you in the shoes of a character who is breaking from within.


12) “Kaikai Kitan” - Jujutsu Kaisen (Opening 1, Season 1)

Yuji Itadori lives a normal life... until the supernatural unexpectedly crashes into him. Curses, exorcists, cruel rules: he enters a world where death is close and courage is not always enough. Yet, the anime maintains a modern energy, endearing characters, and a pace that doesn't let go.

The opening reflects this: an immediate flow, ultra-fluid editing, and a "dark pop" that hooks you from the very first seconds.


13) “Hacking to the Gate” - Steins;Gate

In Akihabara, a small group of friends plays in a lab like grown-ups playing pretend: theories, tinkering, "mad scientist" delusions. Then they stumble upon something too real: a way to influence the past. And there, the series shows you the price of choices: what seemed fun becomes dangerous, and every attempt at correction can worsen the situation.

The opening puts you in this tension: sci-fi sounds, a feeling of looping, images that suggest time tearing apart. It's an intro that says "beware, you're about to lose your footing."


14) “Hikaru Nara” - Your Lie in April (Opening 1)

A prodigy pianist stopped hearing music as he once did. He moves on autopilot, stuck in something heavy, until he meets a musician who lives everything at 100%. She pushes him, shakes him up, awakens him — and the series then talks about beauty, pain, healing, and everything that can only be expressed through art.

The opening reflects this: bright, lively, but with a little fragility beneath the surface. You feel spring… and you also feel it’s going to hit hard.


15) “99” - Mob Psycho 100 (Opening 1, Season 1)

Mob is an ultra-powerful middle schooler, but he doesn't want to be "a hero." He just wants to be normal, manage his emotions, find his place. Except his powers are linked to what he holds within him: the more he endures, the more it builds up... until the famous "100%," when everything overflows.

The opening resembles the anime: experimental, hypnotic, full of visual ideas, with that countdown that puts strange pressure on you. You know it's going to be funny, stylish... and explosive.


Anime Openings FAQ

Still have questions about anime opening themes? Here are the answers to the 10 most frequently asked questions, simple and straightforward.

What is an anime opening?
An opening (or opening theme) is the sequence at the beginning of an episode, usually composed of a song and a montage of images. It serves to set the mood, introduce characters, and sometimes foreshadow the theme of an arc.
What is the difference between an opening and an ending?
The opening starts the episode (energy, introduction, hype), while the ending concludes it (often calmer, more emotional, or "post-episode"). Endings can also serve as a "cool-down" after an intense episode.
How long is an opening usually?
Most last about 1 minute 30 seconds (classic TV format). Some anime shorten the opening in important episodes to save narrative time.
Why do some openings change during a season?
They change to accompany a new arc, introduce new characters, reflect a change in tone, or simply because a long series refreshes its themes to prevent monotony.
Do openings contain spoilers?
Sometimes yes, especially visually. Some openings are very "safe," while others show silhouettes, action scenes, or symbols that gain meaning later. If you want to avoid spoilers, watch the opening after a few episodes or just listen to the music at the beginning.
Why does an opening "stick in your head" so easily?
Because it's designed as a musical hook: a catchy chorus, an effective rhythm, repetitive motifs. And since you hear it in every episode, your brain quickly associates it with the anime's universe, emotions, and key moments.
What is an "anisong"?
"Anisong" is the term used (especially in Japan) to refer to anime songs, whether they are openings, endings, or insert songs (songs used during an episode).
What is an "insert song"?
It's a song used within an episode, often during a key scene (fight, revelation, emotional moment). It's not necessarily an opening/ending, but it can become just as iconic.
Why do some openings have different versions (visuals or music)?
Studios sometimes create variations: Version 2 with new scenes, added characters, animation corrections, or sometimes a "special" version (finale, event episode). For music, there might be a TV version (short) and a full version.
What is the best anime opening of all time?
There's no single answer (it's very subjective), but some frequently appear in rankings and discussions: A Cruel Angel's Thesis (Evangelion), Tank! (Cowboy Bebop), Guren no Yumiya (Attack on Titan), Again (FMA:B), We Are! (One Piece). The "best" mostly depends on your style: epic, nostalgic, dark, or feel-good.

 

Ultimately, a legendary opening is a rare blend: a catchy song, a production that tells a story (without revealing everything), and an emotion that instantly immerses you back into the anime's universe. This selection includes very different styles — from the jazz of Cowboy Bebop to the epic anthems of Attack on Titan, including classic shōnen and more emotional openings — but they all have one thing in common: they have left their mark on a generation of fans.
