Changes

In the final phases of a Tyranid invasion, billions of Rippers are released over the planet. They move across its surface multiplying and consuming every living thing, leaving an empty and desolate wasteland. They are highly ravenous and in great numbers they can pull down and consume creatures many times their own size.

They show surprising mutability. It is speculated that Rippers are a larval form of Tyranid. Eventually, the Rippers will become bloated full of biomass, unfit for combat. At this point, they simply crawl into the [[Reclamation Pool|reclamation pool]]s and to their own demise.
