Masters of the Universe

A chosen player receives a custom Grayskull Compass.
Castle Grayskull generates near world spawn.
/locate grayskull reveals the castle and sword-chest location.
The chest contains the Power Sword.
Holding the transformation button completes a five-second cinematic transformation.
Transformation includes animated posing, energy rings, sky beams, lightning, sound, screen flashes, camera shake, and multiplayer-visible effects.
He-Man form lasts ten minutes.
Lethal damage de-transforms He-Man instead of killing him.
The Grayskull power bar increases by one per hit dealt or received.
Higher power improves damage, defense, speed, and survivability.
Full power matches the Avatar mod’s strongest ability tier.
The Power Sword deals three times netherite-sword damage.
Optional Avatar mod compatibility prevents a player from being both Avatar and He-Man.
The optimized 3D sword retains its texture and correct hand position.
Transformation state, cooldowns, compass target, chosen player, and castle location persist between sessions.
