Siren Head: The Siren's Attacker (Java Port) Horror Mod

The creature spawns naturally at night and targets players, villagers and iron golems. It has 800 health and deals considerable damage, moves quickly, and prefers dark areas where it is hard to see. It constantly tracks its target and launches surprise attacks, and its wide-range strike sends surrounding targets flying a considerable distance. The mod can also control the weather, which lets it shape how often the creature shows up.

Siren's Attacker brings a Java version of the Bedrock add-on of that name, created by Kyrie Guinto. The creature keeps a chase target for over a minute before it despawns, and the mod works in both single-player and multiplayer, with an achievement attached. Forge is the only loader it supports. Files exist for 1.12.2 and 1.20.1, and the latest build is 1.12.2PortV1.0.101 for 1.12.2, published on 2026-05-28. Both the server and each player need the mod, and it is released under All rights reserved, so it is not open source.
