7. Naruto Shippuden – Fourth Great Ninja War Arc

The Fourth Great Ninja War arc lasted several years and was one of the most complicated arcs in the history of shonen. Comprised of the alliance of the shinobi nations against the military of the Akatsuki, the arc contains both tactical military strategy, as well as the most personal aspects of each character.

6. Attack on Titan – Marley Invasion Arc

The Marley Invasion arc of Attack Titan has a combination of hard-hitting battle scenes and some mind-rocking plot twists. The perspective is interchanged, as the author reveals the battle through the eyes of his protagonists as well as the perspective of their enemies. This two-faced style makes the story quite morally ambivalent, forcing a viewer to question who exactly the villains and heroes of the story are. The combats are ferocious, the politics are filled with intrigue, and the secrets forever alter the course of the series.

The arc is a combination of spectacle and heartbreak as people turn adversaries against one another under the influence of reincarnation magic. It puts the boundaries of the Knights of the Clover Kingdom to the test and helps to draw on the main theme of trust. Narratively and technically, it is one of the strongest battles in Black Clover.

4. Demon Slayer – Swordsmith Village Arc

Although not exactly a war in the regular sense of the word, the Swordsmith Village Arc in Demon Slayer is very reminiscent of the cycle of virtually endless conflict and sacrifice. The transfer to the second part of the arc sees it being animated by Ufotable in breathtaking animation, and it begins to incorporate high-ranking demons, thus raising the series to the arena of great battles. The fights involve both personal and grandiose aspects with the introduction of new powers, dire consequences, as well as heartrending references. It is confirmation that even when operating in a more confined environment, Demon Slayer can deliver a battle that feels like one fought in the midst of a battle.

3. Hunter x Hunter – Chimera Ant Arc

The Chimera Ant arc in Hunter x Hunter reinvents what is possible in a war arc. It does not only revolve around the battle between humans and the Chimera Ants but also questions of philosophy, such as ideas of survival, morality, and the distinction between who the predator and prey are. The strategic combat, fast-paced nature, and devastating consequences of this arc make it prominent. Its composition resembles a battle; there are commanders and plans in place, and abundant casualties. Few arcs convey the horrors of War as well as this one.

2. One Piece – Wano Country Arc

The Wano Country arc is the arc in which you feel that One Piece is presented in its most spectacular form.

The arc contains complex world-building, culture, and fights to the end. In addition to the action, Wano also conveys the theme of freedom and oppression, making it a revolution rather than a fight. Its mixture of artistry and depth of narrative makes it one of the greatest battle arcs ever.

1. Attack on Titan – War for Paradis Arc

At the top is the War for Paradis arc of Attack Titan, one of the most dramatic culminations of years of buildup. The battle is both physical and ideological, where former allies fight against each other, and the battle of that sort determines the future of mankind. The ethically questionable nature of the plot, together with clever action sequences, makes this arc as touching as it is technical. It was the supreme climax to all the events that the series had built up to, and as such, it is the masterpiece battle arc in anime.
