Flood bomber form
From Halopedia, the Halo wiki
The bomber form was an airborne Flood form that was encountered during the Battle of the Etran Harborage in February 2531. It attacks by dropping blisters full of Pod infectors on enemies. Bomber forms were spawned from both Flood dens and colonies.
The bomber form was created from an aerial life form indigenous to the Shield World that had been infected and repurposed by the Flood parasite. Its bloated abdomen was similar in shape to the upper torso of a Flood carrier form. Bomber forms used these parts of their bodies to incubate Pod infectors.
Bomber forms had two spindly 'arms' on either side of their massive heads and just before the bulbous rear section. This head had a large, gaping mouth and two large, empty eye-sockets. This feature was largely unique amongst most other Flood forms, which typically utilize sensory antenna as their primary sensor apparatus. The only other mobile Flood form that seems to share this feature was the swarm, which were another indigenous species that was infected and repurposed by the Flood.
