Merg Vol

Merg Vol was a Sangheili and leader of one of the factions of the Covenant that continued fighting against the UNSC after the end of the Human-Covenant War.

Biography
Between March 2553 and July 2557, Merg Vol led a large-scale attack on the human colony of Draetheus V and its moon X50, searching for Forerunner artifacts. After seizing the moon, which was in fact a Forerunner device, he activated the artifact and directed it on Draetheus V in order to disassemble the planet and destroy the UNSC forces there. At the end of the battle, the UNSC ordered Spartan Sarah Palmer to eliminate Merg Vol. She confronted the Sangheili on X50 and after a fierce battle executed him with her M6H magnum sidearm.

Gameplay
Merg Vol appears as the final boss fight of Operation E mission 5. Until the release of Operation F: Hydra, this was the penultimate fight of the game.

After the player defeats three waves of Covenant infantry, Merg Vol appears armed with plasma grenades and a plasma pistol, which he fires overcharged at the player. After the player lowers one of Vol's shields he retreats to one of four pads to recharge, distracting the player with holographic decoys on the other three pads. Once recharged, he will attack the player using active camouflage and dual wielding Energy Swords.

When the player removes Vol's shields a second time, he will recharge yet again. This time he re-emerges with a Hardlight shield, which the player must find a way around. At this point, he is particularly vulnerable to plasma grenades. Once the player removes his shields one last time, Merg Vol will convulse and collapse, at which point the player will be prompted to execute him with Palmer's magnum sidearm.
