Territory: Over many star systems and stretching across multiple galaxies Can increase population numbers by consuming biomass. Far higher when accounting for lesser weapon organisms and biomorphs. Population: Likely at least Quintillions of warrior organisms and ships (during the early stages of the Tyranid invasion, 'a billion times a billion' Tyranids were stated to stand at the rim of the galaxy, despite the fact many Hive Fleets have yet to even arrive). Kardashev Level: Type 1 (Tyranids regularly consume entire planets and scrub them of all energy and life)ДЄge: Unknown implied to be in the billions Tier: 9-C | 9-C to 9-B | At least 8-C | At least 8-C, up to High 6-C with weapons | At least 9-A for Pyrovores, High 6-C for Haruspexes | At least 9-A with Spore Mines, High 6-C with Bio-plasmic cannons | High 6-C | Unknown | High 6-C | High 6-C | High 6-C | At least High 6-C, possibly High 6-AВ | At least High 6-C, likely High 6-A | High 6-AД¬ivilization Tier: Intergalactic Civilization (Tyranids originate from another galaxy and have stretched across many galaxies in their search for prey)Д¬lassification: Alien swarm unified by a Hive Mind Collectively forming a single, monstrous superorganism, the Tyranid swarms sweep over the galaxy and consume everything in their way, using the biomass they absorb to create more and more of their kind while the Hive Mind directs them all with perfect synchronicity. Each and every organism in the Tyranid swarm has been biologically engineered and evolved into weapons of destruction made up of countless organisms working in concert yet appearing to just be one living creature. The Tyranids, also known as the Great Devourer, are an extragalactic swarm of countless alien species unified by a single will and overlapping consciousness, the Hive Mind. This horror fights neither for power nor territory, but rather to feed a hunger so insatiable that it will eventually devour the entire galaxy.' - Inquisitor Lord Kryptman Summary 'An alien threat has risen from beyond the abyss, a swarm so vast that it blots out the stars.
