Flood tank form

The Flood Tank Form is a type of Flood Pure Form. It originally derived by mutating from the Stalker Form.

Description
Tank Forms are slow in comparison to the other Combat Forms but they make up for it with relative resilience and their devastating melee attack, as they are unable to wield weapons with their arms that are shaped into hardened spikes (as opposed to whip-like tentacles exhibited by other Combat Forms). However slow, they can run on all fours for a short period, allowing a short burst of speed to overtake a target much like Jiralhanae from Halo 2 and Halo 3. On occasion Tank Forms eject Infection Forms from their 'mouth' as if regurgitating them (not explosively like the Flood Carrier Forms) as a form of short ranged attack, or an attack to counteract Bubble Shields. Like all of the Pure Forms, The Tank forms cannot be dismembered, only disabled.

The Tank Form is similar in appearance to the Drinol, and may have been inspired conceptually by the deleted Covenant race. There is also a notable similarity between the roles of the Tank Form and of the Covenant Mgalekgolo, and is often mistaken as an infected version of a Hunter, however that is impossible considering that Hunters are a colony of worms and the Tank Form is one single mass.

Trivia

 * Tank forms are the only Flood Pure Forms that are not able to cling onto walls.
 * They are very similar in appearance to the Flood Thrasher Form.
 * There is an easy way to kill a Tank Form other than using a Energy Sword. If you just melee him in between the two tentacles on his head he will die instantly. Although it can be hard to hit it in the kill spot if it's swinging it's arms around and moving around.
 * A common error for people to make is mistake these for infected Hunters. This is not true due to the fact that hunters can't be infected and the Tank Form is a Pure Form.
