Palladium
by ThreeTAG
With Palladium installed, players can build custom superpowers and in-game content from data files instead of writing Java code.
What it does
Palladium is a data-driven utility for creating powers and content. Its data files define abilities and items, so authors can add new superpowers to a world without writing mod code. The mod is a library: other mods such as PantheonSent, Alien Evolution, FSang18's Heropack and Foi1ys Lantern Corps are built on it and add their own heroes, suits and aliens.
Palladium runs on the client and the server, so both need the mod. Files are published for Fabric, Forge, NeoForge and Quilt, all for 1.20.1, with 4.5.9 as the latest build. Palladium requires nothing else, but several optional integrations are available: Condensed Creative, Curios API, Geckolib, KubeJS, Pehkui and Trinkets. The mod is licensed under All rights reserved and is not open source, though its source code, issue tracker and wiki are public.
Key features
Data-driven powers
Abilities are defined in data files rather than compiled code, so new powers can be added by editing files.
Custom in-game content
The same data system produces content beyond powers, letting authors add items and effects to a world.
Addon ecosystem
Ninety-eight other mods build on Palladium, including hero and alien packs that add their own characters.
Optional integrations
Support for Geckolib, KubeJS, Pehkui and other mods is available when those are installed alongside it.

Alien Evolution uses Palladium to let players transform into aliens with their own moves and playstyles.
Who it’s for: Modpack authors and content creators who want to add superpowers and custom abilities to a 1.20.1 world, and players who want the heroes and aliens that addon mods supply.
