Masters of the Universe

by Jsumpter

Masters of the Universe lets a chosen player transform into He-Man through a cinematic sequence, with a Grayskull Compass and Castle Grayskull near spawn as the entry points.

NeoForgeClient and serverAll rights reserved1.21.1

What it does

A player who is chosen receives a custom Grayskull Compass. The compass can locate Castle Grayskull, and the locate command reveals where the castle's sword chest sits. That chest holds the Power Sword, which deals three times the damage of a netherite sword. Castle Grayskull generates near world spawn, so the route to the sword starts close to where players first appear.

A five-second cinematic plays while the transformation button is held, showing a posing sequence, energy rings, beams across the sky, lightning, sound effects and flashes on the screen. Camera shake is visible to other players in multiplayer. He-Man form lasts ten minutes, and lethal damage returns the player to normal form instead of killing them.

The mod requires Geckolib and playerAnimator. It is built for NeoForge and runs on client and server, so both the server and every player need it. Files cover 1.21.1 only, and the mod is released as 1.0.0 for 1.21.1, published on 2026-06-06. The code is not open source and is distributed under All rights reserved.

Questions

Does Masters of the Universe need Geckolib and playerAnimator?

Yes. Geckolib and playerAnimator are both required dependencies and must be installed alongside the mod.

Do both the server and players need the mod?

Yes. The mod runs as client and server, so the server and every player need it.

Can the transformation be used together with the Avatar mod?

An optional compatibility layer prevents a player from being both an Avatar and He-Man at the same time.

Are transformation state and compass target kept between sessions?

Yes. The cooldowns, the compass target for the chosen player and the castle location persist between sessions.
