Ghalak the Colossus, Forge Warden

Ghalak the Colossus, Forge Warden is the final boss of the Volundr Forge in the European Dead Zone.

Gameplay
Ghalak's main weapon of choice is a Red Legion Slug Rifle, which fires high-impact kinetic slugs at a rapid rate, although when his targets are out of range, he will switch to Cabal Cluster Missiles, which behave in the same way as the Colossus' missiles, inflicting blindness and slowness effects upon detonation. When faced at close range, he will slam the ground with his fist to generate a shockwave that has high knockback force; he will also slam into the ground when charging with his jetpack. Ghalak will occasionally envelop himself in an immunity shield, which can only be disabled by shooting the small drones that surround it. As the Forge Warden, he must be killed to access the Volundr Forge. With his high-impact weaponry, disorienting missiles, high mobility, and drone shielding, Ghalak will pose a serious threat to underleveled Guardians.

Trivia

 * Appearance-wise, Ghalak has a similar armor and weapon setup as Valus Thuun. This could signify that Valus Thuun and Ghalak might have a similar goal, or serve in the same unit.
