Carriers are a strain of Chimera which serve a non-combatant role in which they journey to the battlefield to collect infected humans who have succumbed to a Crawler attack. In appearance they are similar to a very large floating jellyfish and have numerous eyes.
The Carriers' sole basic purpose is to gather and ferry captured humans that are infected with the Chimeran virus to conversion centers where humans are converted and transformed into Chimera. Thus playing an important role by gathering the infected to amass Chimeran forces. Furthermore, the same infected people serve as the Carriers' food and, as such, not all the bodies survive to be converted. During the early Chimeran invasion ofBritain, Carriers would form caravans that were hundreds of miles long.
