A Genestealer Broodlord is a Tyranid synaptic organism, often the first to infiltrate a victim world. Noted for their combat skills and adaptability, they are key to Genestealer Cults, coordinating attacks. If a Broodlord falls, a purestrain Genestealer replaces it. The Genestealer Patriarch, a similar entity, unifies its cult through a subconscious link, the Broodmind.
