Primus: AlienEvo AddonPack

by Yugatsuj

Primus: AlienEvo AddonPack adds a Pyros homeworld, with its volcanoes, villages and wandering Pyros, to Alien Evo through Ad Astra planets.

ForgeServer-side onlyMIT License1.20.1

What it does

The addon is built to bring the Ben 10 classic alien homeworlds into Ad Astra, with the Pyros planet as its first addition. It adds world generation, block and item textures, and structures such as Pyronite villages and volcanoes that give the planet a hellish look. Wandering Pyros can be met there, and players can trade with Pyronites.

Pyronites drop Pyronite flakes when a brush is used on them, and the flakes can be used to tame Crabdozers. A tamed Crabdozer works like a horse or dog hybrid, so it can be mounted, commanded to sit, and will join in when its owner attacks something. The addon works with Alien Evo and with Addon Ad Astra, and it is released under the MIT License, though it is not open source. Only the server needs it, so players join without installing it. The addon is for 1.20.1 only, and the latest Forge file, 0.2.1, was published on 2026-08-02.

Key features

  1. Pyros planet

    Volcanoes, lava and hellish terrain form the Pyros homeworld, reached through Ad Astra travel.

    Villages hold loot such as iron, gold, frigyd shards and other materials worth collecting.

  3. Pyronite trading

    Players can trade with Pyronites, and a brush used on them yields Pyronite flakes.

  4. Tameable Crabdozers

    Pyronite flakes tame Crabdozers, which can be ridden and commanded to sit.

  5. Wandering Pyros

    Wandering Pyros appear across the planet, and Heatblast is not yet available from them in this version.

Use cases

Who it’s for: Players of Alien Evo with Ad Astra who want to explore the Pyros homeworld. Server owners run it alone, since clients need nothing installed.

Questions

Does Primus: AlienEvo AddonPack need to be installed on the client?

No. The addon is server-side only, so only the server needs it and players can join without installing anything.

Which Ad Astra features are needed to reach the Pyros planet?

Travel to the homeworlds requires a tier 4 rocket first, and the Jet Suit is recommended for reaching them.

Why should travel to Pyros be careful about height?

Players traveling to Pyros must stay above Y level 70, since a lower Y level can end up in lava.
