Seeder infector

The Seeder Infector is a type of Flood infection form. Seeder infectors are employed by the Flood as lighter-than-air forms that swim through the sky and attack aircraft. Seeder infectors can infect aircraft and convert them to Flood use, but are also capable of spitting bone fragments of their victims at enemy targets.

History
Seeder infectors were encountered by UNSC and Banished forces during the Second Ark Conflict in 2559.
