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.

Gameplay
In their first appearance in the Vault of Glass Raid, Fanatics resemble standard Goblins who have been decapitated, and will glow and sparkle green. Upon being destroyed, they will leave behind a green 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 or are damaged enough, they will explode, leaving behind a pool of Radiolaria which damages those who step into it.

Trivia

 * In Destiny 2, they serve a similar purpose to Cursed Thrall, such 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.
 * Their first and only appearance in the original destiny series was in the Vault of Glass (Raid) during the fight with the Templar.
