The Tyranids are one of the most terrifying factions in Warhammer 40,000. A galaxy devouring alien swarm driven by pure biological instinct and a single, overwhelming purpose: consume all life.
Invading the Milky Way from unknown extragalactic regions in massive hive fleets. They exist only to harvest biomass stripping entire planets of all organic matter, including plants, animals, oceans, and even microbial life.
They don’t negotiate. They don’t retreat. They feel no fear.
They don’t conquer worlds.
They devour them.
