Stargate Replicators Mod

Replicators feed on breakable blocks in the world. After they consume enough material they split and spawn exact clones of themselves, so an untreated infestation keeps growing. Their swarm is programmed never to despawn, which means a group stays in an area until players physically hunt it down. Replicators can climb walls like spiders and survive indefinitely underwater without drowning. Players can start an infestation on purpose by crafting a Replicator Spawn Egg from eight iron ingots surrounding one diamond. Groups of a few bugs also break away from larger swarms to search for resources.

The mod is built for a late-game threat. Attacking a single peaceful Replicator alerts the whole nearby pack, which retaliates against the attacker. When a swarm grows by twenty more members in a localized area, it turns aggressive and hunts players and other mobs in sight. Replicators spit acid at a distance that poisons targets before they close in to bite, and they are fully immune to lightning and other electrical damage.
