Grand Blue bosses
Two story fights gate your island progression, and one hourly event pays the bills. Learn the difference before you sail.
Story bosses
| Boss | Location | Phases |
|---|---|---|
| Axe-Hand Morgan | Anchor Town — end of the Captive Swordsman chain | 2 |
| Buggy Clown | Clown Town — via the Mayor’s chain | 2 |
The hourly world boss event
Choppy, Kuro and Logan rotate through the world boss event that lands every hour at XX:00. These are server events, not story encounters — everyone piles in, damage is shared, and the rewards (Celestial Coins, chests, named World Boss Chests) make it the best money in the game once you can survive it.
One rule for both story fights
Both story bosses keep fighting after their first health bar drops. Morgan continues into a second phase inside the same encounter, and Buggy Clown punishes anyone who stops to loot their focus. Assign your skills before you walk in, keep blocking after the first bar breaks, and never start a story fight you cannot finish — dying means the walk back.
