Minecraft Dungeons:Vengeful Heart of Ender

The Vengeful Heart of Ender is the final boss of the Echoing Void DLC. It is found in the Broken Citadel.

Appearance
Before entering the Broken Citadel, the Vengeful Heart of Ender first appears as a long black centipede-like creature with a segmented body, a pink energy connecting between each of them, six small legs, several pink spots all around its body and has a small two-horned head with two pink eyes and mouth. Upon reaching the End Shrine though, it undergoes a transformation, where it becomes larger and more monstrous, now possessing eyes throughout most of its black segments, four small legs, a long neck, and a head possessing two long horns with the tips lit with purple flames, along with its jaw. It then gains an extra eye and jagged teeth.

Behavior
Throughout the DLC, the Vengeful Heart of Ender still in its premature state crawls around the level, stalking the player. Upon encountering it at its shrine, a cutscene plays where it opens and enters a large portal and then emerging in its final form. A cutscene also plays after defeating it where it spasms lasers uncontrollably, slicing its body apart in the process, before losing its power and toppling over and then disintegrating with its ashes blowing away into the obscurity of The End to be lost forever. It has multiple attacks that it uses in random order.

Imperfect form
During the DLC, it is shown that the Vengeful Heart of Ender in its first form is able to crawl on walls while stalking the player.

Perfect form
The Vengeful Heart of Ender quickly charges at the player, dealing constant damage if they are in its way.
 * Charge

The Vengeful Heart of Ender spins its body segments around, similar to one of its past self's attack, releasing several replicas of the Orb of Dominance which fall to the ground and linger for a moment. But instead of leaving purple flames behind, the replicas will explode in a larger radius. This attack also flings condense void in random spots near itself, which expands when it hits the ground, then disappear afterward.
 * Void bomb

The Vengeful Heart of Ender shakes, and several endermites come off of it.
 * Endermite scatter

The Vengeful Heart of Ender occasionally will absorb some endermites that it spawned before, regenerating some hp.
 * Endermite health leeching

The Vengeful Heart of Ender becomes invincible and goes to the center of the arena, covering it in a void shroud.
 * Void pool

It begins sucking the player toward it and, after a few seconds, explodes, dealing massive damage. This attack is performed multiple times in a row.
 * Void pull and void spew

While doing this, it also constantly summons endermites enchanted with Sharpness.
 * Endermite feast

Several void crystals erupt from around the edges of the arena, and the Vengeful Heart of Ender begins shooting many energy projectiles off of its body segments in circle formations. The void crystals reflects any oncoming projectiles that hits them in a random direction, making it harder for players to avoid. The Vengeful Heart of Ender shoots more void crystals every time this attack is done.
