Flesh Symbiote

Flesh Symbiote is a Forge mod for Minecraft 1.20.1. It adds an artificial symbiotic tissue that a player injects with a Flesh Injector. Once it takes hold, the tissue transforms the player's body into a living flesh creature with alien eyes spread across the skin, and the eyes blink at separate intervals. Tentacles grow back when they are used, and they serve for movement, feeding and combat. A dormant symbiote sample can be absorbed after it is found inside meteor craters, which raises the Flesh Evolution level and makes the tentacles stronger.

The symbiote has three combat forms. Bulwark blocks projectiles and reduces magic damage by 50 percent. Lurk makes nearby hostile mobs lose interest in the player until the player attacks first. Abomination releases the symbiote's predatory instincts, so tentacles strike nearby living creatures. Its abilities have much shorter cooldowns than ordinary symbiotes. When stamina runs out, abilities draw on the host's health, and if hunger is fully depleted the flesh can briefly seize control of the body. The symbiote can also devour flesh blocks to restore hunger, and it can separate from the body to envelop blocks or merge with living creatures.

Flesh Symbiote requires Symbiote: A Bonding Experience. The server and every player need the mod installed. Files are published for Forge only, and the latest file, 1.1, is for 1.20.1 and was released on 2026-09-26. The code is released under the CC0 1.0 Universal license and is not open source.
