Honor Guard Councilor
From Halopedia, the Halo wiki
Honor Guard Councilor is a fan-derived title for a particular glitched Elite model that serves as the final opponent in Halo 2's campaign level Gravemind. This glitch can be attributed to the game's programming due to an incorrect coding; the Elite model was meant to be a Zealot.
The Honor Guard Councillor, who appears at the fore of the bridge between the Mausoleum of the Arbiter and the Far Tower, is flanked by two SpecOps Elites wielding Plasma Rifles or Carbines (and a pair of Ultra Elites on higher difficulties). The Honor Guard Councilor is extraordinarily powerful and on Normal difficulty or higher requires at least two Fuel Rod Gun hits to kill, or multiple Energy Sword slashes to defeat. The Honor Guard Councilor is programmed to have the power and skills of a Zealot. It always wields an Energy Sword.
Though the armor is always white with Honor Guard pieces, there are some variations, mostly with the helmet. In addition to the helmet variations below, there are occasions where the glitched Elite has Rtas 'Vadum's face - that is, where the Elite is missing two mandibles. The Elite can appear with the following permutations:
The Honor Guard Councilor's appearance results from the usage of a missing tag. In Halo 2, every enemy in the Campaign has variations, which increase the game's realism. The variations would be chosen at random each time a level was played; they determined that enemies would act and sound differently. This differs from Halo: Combat Evolved, where some enemies, like Elites, always used the same lines.
Each Elite tag was suffixed with an underscore and a three-letter code denoting the Elite's voice actor. Tags whose name ended in
So these are all of the Elite tags in Halo 2:
On most levels, all a programmer has to do is code the game to produce one Minor Elite, for example, and the game itself will randomly choose between the Minor_dog and Minor_scl variations. Programmers do have the option to force the game to use a particular variation.
However, not all levels have both sets of tags for all enemies. In Metropolis, for example, all Grunts sound the same, because the tags voiced by Brian Posehn were omitted from the map's code, leaving only the Grunts that were voiced by Joseph Staten. Bungie decided to use only one of the two Grunt variations in the game.
This was also done on Gravemind: Elites'
At this point, the game knows to spawn an Elite with the power and weapons of a Zealot, but it does not know what the armor is supposed to look like. It automatically chooses the default armor color, white, but there is no default helmet. The game thus chooses between the available helmets (or lack thereof). The face is also randomized, sometimes causing the glitched Elite to have Half-Jaw's face and eyes. And for unknown reasons, the game always enables the "Honor Guard" armor—all Elite tags have a setting that gives them Honor Guard armor, but it is supposed to be disabled on most Elites, including Zealots.
