Stalker Form



The Stalker Form is a Flood Pure Form that specialises in stealth and agility. It is apparently made from the recast bone of dead enemies. Upon being heavily damaged it will mutate into a Ranged Form or Tank Form.

This form sits low below your view and their attacks can go widely unnoticed until you look down. They are able to crawl on walls and ceilings like a spider with relative adeptness and capable of tremendous jumps like the normal parasitic combat forms. A possible flaw in the Halo 3 AI, it has been observed to rarely attack the player, and normally prefers to mutate itself into one of the two other Pure Forms.
