Sekiro: Shadows Die Twice is known for its intense combat and unforgettable boss fights. Every major battle pushes players to master parrying, posture management, and patience. Unlike many action games, you can’t simply overpower enemies—you have to truly learn how they fight.
Throughout the game there are many incredible bosses, but a few stand out as the most memorable. Whether it's because of the challenge they present, their unique mechanics, or how satisfying they are to defeat, these fights left the biggest impression on me.
Here are my Top 5 favorite bosses in Sekiro: Shadows Die Twice.
#5 Gyoubu Oniwa
My fifth favorite boss is Gyoubu Oniwa, the first major boss encounter in the game.
When you first enter the battlefield, Gyoubu charges in dramatically on horseback while shouting his name, instantly setting the tone for what Sekiro boss fights are going to be like. The scale of the fight can be intimidating at first since he rides around the arena swinging a massive spear.
For new players, this battle can feel overwhelming. Gyoubu moves quickly around the battlefield and attacks from a distance, which can make it seem difficult to find openings.
However, once you start understanding how the combat works, the fight becomes much more manageable. A simple strategy is to hold block while he finishes his attack sequences, then get a few hits in when he pauses. If you're comfortable with deflecting, you can also parry several of his attacks to break his posture faster.
What makes Gyoubu such a great boss isn’t necessarily the difficulty—it’s the moment in the game. This is the fight where players truly begin to understand how Sekiro’s combat system works. It’s the first big test, and defeating him feels like a major accomplishment early in the game.
#4 Headless Ape
My fourth favorite boss is the Headless Ape, which is easily one of the most surprising fights in the entire game.
The battle begins against the Guardian Ape, a massive and chaotic beast that fights wildly with powerful attacks. After a long and difficult fight, you finally manage to cut off the ape’s head, which feels like the end of the battle.
But then something completely unexpected happens.
The ape stands back up.
The second phase is where this fight becomes truly memorable. The headless ape suddenly starts wielding a sword and attacking in a completely different way. Instead of fighting like a wild animal, the battle becomes more of a rhythm-based duel that requires careful deflecting.
The first time experiencing this moment is both shocking and frustrating. But once you learn the timing of the attacks and start getting the parries down, the fight becomes incredibly fun. The creativity of this boss design makes it one of the most unique encounters in Sekiro.
#3 Owl Father
My third favorite boss is Owl Father, specifically the version found in the Hirata Estate memory.
There are two versions of Owl in the game depending on the choices you make, but the Hirata Estate fight is easily the more difficult one. This version of Owl is extremely aggressive and constantly pressures the player.
He attacks quickly with his sword, throws firecrackers to stun you, and uses tricky shinobi techniques that punish hesitation. It feels like fighting another highly skilled shinobi rather than a typical boss.
This fight is incredibly challenging because Owl rarely gives you time to recover. You have to stay focused and react quickly to everything he does.
In my opinion, this is the second hardest boss in the entire game. There are very few tricks or shortcuts that can make the fight easier. You simply have to master the mechanics and win the duel through skill. That’s exactly what makes defeating Owl Father feel so rewarding.
#2 Isshin, the Sword Saint
My second favorite boss is Isshin, the Sword Saint, the final boss of the game.
This fight is widely considered the hardest battle in Sekiro, and it’s easy to see why. Isshin has four total phases, each introducing new attacks and mechanics. If you die during any phase, you must start the entire fight over again.
The battle tests everything you’ve learned throughout the game. Perfect deflections, positioning, reaction time, and understanding enemy patterns are all essential to winning.
The first time fighting Isshin can feel almost impossible. His attacks are fast, powerful, and unpredictable. But once you begin to understand his patterns, the fight becomes incredibly satisfying.
After playing through the game multiple times, I eventually found a strategy that worked perfectly for me. By my second through fifth playthroughs, I was actually able to defeat him on my first try each time. Pulling off that strategy and winning the fight never stops feeling rewarding.
Even though Isshin is the hardest boss in the game, there is still one boss that I enjoy fighting even more.
#1 Genichiro Ashina
My number one favorite boss in Sekiro: Shadows Die Twice is Genichiro Ashina.
Genichiro is the second major boss players encounter, but he serves as one of the most important fights in the entire game. Up until this point, many players are still trying to understand how Sekiro’s combat system really works.
Genichiro forces you to learn.
The fight has three phases, each increasing in difficulty. He combines fast sword attacks with bow shots and powerful lightning techniques that can easily catch players off guard.
What makes this fight so great is how perfectly it represents the core gameplay of Sekiro. The battle rewards players who master parrying and punish those who rely too much on dodging or running away.
Once you start successfully deflecting his attacks and matching his rhythm, the fight becomes incredibly satisfying. Every perfect parry feels rewarding, and defeating him feels like you’ve truly improved as a player.
Sekiro is a game about learning and adapting, and Genichiro Ashina is the boss that teaches that lesson better than any other fight in the game. That’s why he stands as my favorite boss in Sekiro: Shadows Die Twice.
