The boss list below is what Mojang has actually shown, which is a smaller set than what the game ships with. Three fights appeared in official footage before launch, and the achievement list names several more encounters without footage. Attack descriptions come from the footage itself; no numbers are published, so there are none here.
Twisted Warden
The signature fight. A soul-corrupted Warden, dramatically larger than anything in the first game, guarding the Deep Dark portal in The Sift. The fight, as shown in the official hands-on preview:
- A sonic boom that snipes players from across the arena
- A twisting spin that closes ground fast and can launch players off the map
- Soul-based area effects that light up the fight space
Community lore, which Mojang frames as speculation, says the Warden was corrupted by the stray souls that wander The Sift. Mechanically, the counterplay demonstrated on stream was simple: keep moving, use jump attacks to create openings, and use group revives when the boom finds you. The Sift, where it lives.
Copper Monstrosity
A boss with a dedicated opening cutscene that the official preview compared favorably to animation work. Its shown behaviors: spreading lightning across the arena, charging players, and general pressure that punishes standing still. The preview's running joke, that it wants revenge for what players have done to copper golems, is commentary, not lore. The achievement list names a quest to defeat "a Copper Monstrosity" summoned by an Evoker.
Monarch and the Monarch's Echo
The boss Mojang demoed live on the Minecraft Live stream, and the one they called genuinely difficult. The gimmick is the Echo: halfway through the fight the Monarch creates a clone of itself. Killing the Monarch destroys both, but focusing the original while the Echo harasses you is the harder route, so the fight forces a choice between cleaning up the clone and gambling on the fast kill. The achievement list names "defeat a Monarch" as a hidden quest.

Named in the achievements, not yet shown
The achievement list names more encounters that official footage has not shown. They are listed here as named, with no mechanics attached, and the full achievement list maps every quest row:
| Encounter | Achievement hint |

| Prime Enchanter | "Past Their Prime" |
| Wandering Witch | "Craftier than Witchcraft" |
FAQ
How many bosses are in the game?
Not published. Three are shown in footage, several more are named in achievements, and the full count will only be known from the community's first full playthroughs.
Is the Twisted Warden the final boss?
No official source says so. It guards the Deep Dark portal in The Sift, which makes it a story milestone, but the achievement list implies encounters beyond it.
What is the best way to prepare for these fights?
The mechanics shown reward mobility and sustain: jump attacks for burst, artifacts like the picnic blanket for healing, and teammates for fast revives. The combat systems. Specific boss counters will be added when the community documents them.
