Flood Juggernaut

Summary
The Flood Juggernaut is the name given to a large Flood form found encoded in the Halo 2 disc the same way as the Engineers in Halo 1. The Flood is very large, perhaps twice as tall as the Master Chief, hence the name "Juggernaut". The Flood Juggernaut is thought to be the infected form of either an Engineer or a Drinol, and was removed from the game with its base form. Because of its size, some also speculate that it is a Flood-infected Brute.
