Anime Breaker currently has six Secret Bosses hidden across Alien Planet, Titan District, Hidden Leaf, Sin Village, Hunter City, and Pirate Village. These bosses are worth finding beyond completing your Index, as they provide repeatable world-specific Accessories, Gold, Raid Tickets, and extremely rare Secret Avatars.
Most Secret Boss rooms are concealed behind terrain or inside buildings that don’t appear accessible. Once you know the correct landmark, however, reaching each boss is straightforward.
All Anime Breaker Secret Boss Locations
| World | Secret Boss | Location | Notable Reward |
|---|---|---|---|
| Alien Planet | Saiyan Prince | Mountain behind Alien Raid Portal | Scanner |
| Titan District | Ace Captain | Building near Buzzcut Scout | Captain Cape |
| Hidden Leaf | Copy Ninja | Behind red building near Akimichi Titan | Ninja Vest |
| Sin Village | Lion Sin | Cave below bridge on left side of lake | Demon Wings |
| Hunter City | The Goliath | Building behind red car | The Goliath Avatar, Hunter Raid Tickets |
| Pirate Village | Fire Fist | First windmill on right | Fire Fist Avatar, Fire Fist Hat |
The first four worlds provide several particularly useful Accessories. Captain Cape grants 2x Damage, while Demon Wings provides 4.5x Energy.
Saiyan Prince Location in Alien Planet
Alien Planet’s Secret Boss is Saiyan Prince, based on Vegeta.
Start at the Alien Raid Portal and move behind it. Head toward the right and continue until you reach the mountain along the edge of the area.
Part of this mountain doesn’t have collision. Walk directly through the terrain to enter the hidden boss room.
Saiyan Prince has approximately 750M HP, making him the most accessible Secret Boss for players early in their progression.
| Reward | Drop Chance |
|---|---|
| Saiyan Prince Avatar | 0.01% |
| Scanner | 100% |
| Gold | 100% |
| Alien Raid Ticket | 4% |
The Scanner is the world-specific Accessory associated with this boss. Although the Accessory itself is guaranteed, its rarity is rolled separately, giving you a reason to continue farming for better versions.
Ace Captain Location in Titan District
The Titan District Secret Boss is Ace Captain, inspired by Levi.
Use the Buzzcut Scout enemy as your starting landmark. From there, head right and continue forward until you find a rock beside a nearby building.
Climb onto the rock and move into the building to access the hidden boss room.
Ace Captain has approximately 7.86T HP.
| Reward | Drop Chance |
|---|---|
| Ace Captain Avatar | 0.01% |
| Captain Cape | 100% |
| Gold | 100% |
| Titan Raid Ticket | 4% |
The Captain Cape is particularly useful because it provides a 2x Damage bonus. That can make Ace Captain worth revisiting even after you’ve progressed beyond Titan District.
Copy Ninja Location in Hidden Leaf
Hidden Leaf contains Copy Ninja, a Kakashi-inspired Secret Boss.
Find the Akimichi Titan mob and look for the large red building to its left.
Cross or jump over the middle section of the area, then circle around to the back of the building. Copy Ninja is hidden behind the structure.
The boss has approximately 98.3Qa HP.
| Reward | Drop Chance |
|---|---|
| Copy Ninja Avatar | 0.01% |
| Ninja Vest | 100% |
| Gold | 100% |
| Leaf Raid Ticket | 4% |
The Ninja Vest is Copy Ninja’s world-specific Accessory. Repeated kills let you continue rolling for better Accessory rarity while simultaneously farming Gold and Leaf Raid Tickets.
Lion Sin Location in Sin Village
The Sin Village Secret Boss is Lion Sin, based on Escanor.
Start at the large bridge in the center of Sin Village.
Jump into the water and follow it toward the left side of the lake. Stay near the edge and look for a cave-like opening underneath the terrain.
Enter the opening to find Lion Sin.
With approximately 1.22Sx HP, Lion Sin represents a substantial jump in durability compared with Copy Ninja.
| Reward | Drop Chance |
|---|---|
| Lion Sin Avatar | 0.01% |
| Demon Wings | 100% |
| Gold | 100% |
| Sin Raid Ticket | 4% |
The main Accessory here is Demon Wings, which provides a 4.5x Energy bonus.
The Goliath Location in Hunter City
Hunter City’s Secret Boss is The Goliath, inspired by the Ant King.
Starting from the Hunter City spawn, travel straight through the area until you find a red car.
Go behind the car and jump onto the nearby crystal. Use the extra height from the crystal to enter the building directly behind it.
The Goliath waits inside and has approximately 768Oc HP.
The boss can provide The Goliath Avatar, Hunter City’s world-specific rewards, and Hunter Raid Tickets. As with other Secret Bosses, the Avatar is an exceptionally rare reward, while repeat farming is useful for obtaining Raid resources and improving Accessory rolls.
Fire Fist Location in Pirate Village
Pirate Village’s Secret Boss is Fire Fist, based on Ace.
From the Pirate Village spawn, move forward while staying along the right side of the map.
Watch for the windmills as you progress. Fire Fist is hidden inside the first windmill on the right.
Enter it to reach the boss room.
Fire Fist has approximately 27.6EB HP, making him the toughest of the six Secret Bosses listed here.
| Reward | Drop Chance |
|---|---|
| Fire Fist Avatar | 0.01% |
| Fire Fist Hat | Guaranteed Accessory drop |
| Gold | Guaranteed Gold drop |
| Pirate Raid Ticket | 5% |
The Fire Fist Hat provides a 1.5x Gold bonus, while the Fire Fist Avatar has a 10,000-attempt pity and can only be obtained once.
You’ll need to reach Pirate Village, World 6, before you can farm Fire Fist. The progression barrier leading out of the previous area requires roughly 6 Oc Damage to break, although progression values can change with balancing updates.
How Secret Boss Accessories Work
Secret Bosses have two important reward systems: Accessories and Secret Avatars.
Accessories are repeatable.
Defeating the appropriate Secret Boss guarantees its associated Accessory, but the rarity is rolled separately. Getting the item once therefore doesn’t necessarily end the grind.
For example, you can continue farming Fire Fist after obtaining the Fire Fist Hat to search for a stronger rarity roll.
This also means repeated Secret Boss farming can progress several systems simultaneously, since you’re gaining additional chances at Accessories while collecting Gold and Raid Tickets.
How Secret Avatar Drops and Pity Work
Secret Avatars are considerably rarer.
A 0.01% drop chance corresponds to one natural success per 10,000 kills on average. That doesn’t mean RNG guarantees the Avatar within 10,000 attempts.
Fire Fist addresses this through a 10,000-attempt pity, guaranteeing the Secret reward once the required number of attempts is reached if it hasn’t already dropped.
The Fire Fist Avatar is also marked as a Drops Only Once reward. Once obtained, it won’t continue appearing as a duplicate.
Its Accessory system remains separate, so you can continue farming Fire Fist afterward for better Fire Fist Hat rolls and Pirate Raid Tickets.
How to Level Secret Avatars
Secret Avatars don’t progress most efficiently by simply equipping them and defeating random enemies.
Instead, equip the Avatar and defeat the corresponding enemy represented by that Avatar.
For example, leveling the Fire Fist Avatar means returning to the relevant Fire Fist enemy rather than grinding unrelated NPCs elsewhere.
This gives the corresponding boss additional value after you’ve obtained its Avatar. You can work on Avatar progression while continuing to collect Gold, Raid Tickets, and Accessory rolls.
Which Secret Boss Should You Farm?
A useful progression strategy is to farm the Secret Boss from the highest world you can defeat quickly and consistently.
This keeps the rewards relevant to your current progression and can also make Raid Ticket farming considerably faster.
Fire Fist provides a good example.
| Pirate Village Enemy | Pirate Raid Ticket Chance |
|---|---|
| Fire Fist | 5% |
| Pirate Hunter | 0.5% |
Fire Fist therefore has 10 times the Pirate Raid Ticket drop rate per kill compared with Pirate Hunter.
The benefit depends on kill speed. If a Secret Boss takes too long to defeat, farming regular enemies may still be more practical until your damage improves.
As your build becomes stronger, however, repeatedly defeating your current world’s Secret Boss can combine several progression goals into one grind: Accessories, Secret Avatars, Gold, and Raid Tickets.
Once you’ve moved comfortably into later worlds, there’s generally more progression value in farming the Secret Boss associated with your current content than repeatedly defeating an early boss solely because it dies faster.
