Heretic Unggoy
From Halopedia, the Halo wiki
Summary
The Heretic Grunts followed their Elite counterparts in the rebellion against the Covenant's High Council. They started as members of an artifact retrieval group led by the Elite Sesa 'Refumee. When he and his Elites chose to rebel against the High Council, the Grunts followed them.
Appearance
These Grunts have different methane tubes than their non-heretic counterparts. They have just two round tubes, instead of the pointed-pyramid shape (and the occasional curved-Pyramid shaped ones, only seen in Halo 1). Another feature of the Heretic Grunt armor is a small mouthbreather that exposes a Grunt's teeth.
Unlike the armor of the Heretic Elites, there is only one uniform color for a Grunt's armor, which is a shining, golden-brown. Because of this, there is no hierarchy or ranking system, and Heretic Grunts are inferior only to Heretic Elites.
They're seen only in the levels The Arbiter and Oracle, both in Halo 2.
Combat
Heretic Grunts fight differently than the Covenant-loyal Grunts normally encountered by one fact: They never try to escape, even during Easy difficulty. Though they may say "They got our Elite, run!" or "Run Away!", a Heretic Grunt will stand its ground. The only exception to this rule is when a Heretic Grunt is stuck with a Plasma Grenade, needles, or otherwise knows it will soon die.
Heretic Grunts are also superior to their Loyalist counterparts by their equipment. Heretic Grunts always wield Needlers or Fuel Rod Guns and never the weak, unaccurate Plasma Pistol that is so often overused by their counterparts.
They are also far hardier than the average Unggoy. Any Heretic Grunt can take as much damage as a Major Grunt.
