The Undying Mind

"When the Undying Mind is threatened, its ancient creators step through time portals to defend it, ensuring that it will continue to thrive, until the Vex once again control the Black Garden."

- In game description

The Undying Mind is a Vex Hydra boss in the strike mission The Undying Mind. It is said to be an ancient Vex Mind, feared even by its fellow Vex, that seeks to revive the Black Heart and seal the Black Garden away from the Guardians once more. The Undying Mind was created by the Precursors and laid dormant in the Black Garden, until the destruction of the Black Heart.

In the Season of the Undying The Undying Mind re-establishes itself in the Vex network after the Destruction of the Consecrated Mind, Sol Inherent and Sanctified Mind, Sol Inherent, and directed the Sol Divisive’s invasion of the moon, in addition, it established itself across thousands of timelines by creating copies of itself. The Mind was unreachable until Ikora Rey constructed a Vex portal from Vex chassis components, allowing the Guardians to venture into the timelines where the Mind had established itself and destroy it once again.

"Interesting, undying, huh? What do you suppose they meant by that." "I'll alert the Speaker. Let's find out."

The Undying Mind is a unique Hydra in that it has three shields instead of one. When it first spawns, the passage which the player came from will be blocked, ensuring that there is no escape. It also has the ability to "detonate" when a Guardian gets too close, instantly killing them, and can summon endless waves of reinforcements, and while doing so, two vertical confluxes will send out blinding waves of energy to disorient Guardians. It is otherwise functionally identical to Hydras in that it is capable of blasting through a Guardian's shield very quickly with its Aeon Maul.

Trivia

 * While the Undying Mind's Aeon Maul blasts are orange-colored (Solar) the killcam clearly shows they are the same as ordinary Torch Hammers or Aeon Mauls (Void). This may be a developer oversight.
 * The Undying Mind is the third Axis Mind to return. Sekrion, Nexus Mind and Dendron, Root Mind being first and second respectively.
 * The Undying Mind's appearance in Destiny 2 has been slightly altered, bearing a resemblance to The Templar in D1.
