Fanatic

Fanatics are a Vex unit found in the Vault of Glass and on Vex machine worlds such as Nessus. In Destiny, they are headless Goblins that glow green, and carry a debuff called the "Mark of Negation". In Destiny 2, they appear as standard Vex enemies, where they have a modified appearance and abilities.

Overview
All Fanatics walk with a rather disrupted, uneven gait and all are missing their left arm, from which wires can be seen to sprout. Their chassis is also seen to be scratched and damaged in various areas. It is unknown what the true origin of Fanatics may be, but thus far they seem to be Goblins that have received such severe damage that the Vex Collective has seen no further use for them other than as a spreading vector for their infectious Radiolarian Fluid.

Gameplay
In their first appearance in the Vault of Glass Raid, Fanatics resemble standard Goblins who have been decapitated and deprived of their left arm, and will glow and sparkle green. They run after players, firing their rifles and detonating if thery come close. Upon destruction, they will leave behind a glowing pool. Should a player step into this pool or come into contact with the Fanatic itself, they will be afflicted with the "Mark of Negation" debuff, and only have a few seconds until they are killed by the Templar's Ritual of Negation.

In Destiny 2, Fanatics will slowly advance toward the player while firing on them with their Slap Rifle and emitting glitched screams. Once they get too close (in which case they briefly glow blue) or are damaged enough, they will explode in a Solar blast, leaving behind a pool of Radiolaria which damages those who step into it. If killed using a Finisher, they will be launched backwards with a delayed detonation, and will not leave a Radiolarian pool behind.

Trivia

 * In Destiny 2, they serve a similar purpose to Cursed Thrall, as exploding when a Guardian gets too close. This makes the fanatic the third kamikaze unit to appear in the Destiny series, following the Cursed Thrall and Exploder Shank.
 * As a result of missing their heads, Fanatics are the only Vex without some kind of red eye.
