Shrieker

Shriekers are a class of Hive, possessing a metallic body containing an energy core inside.

Overview
These ever-watchful sentinels are believed, in some circles, to serve as the eyes of the Hive's innermost covens, allowing powerful Wizards and Knights to watch over their domains. Others believe Shriekers are nothing more than weapons meant to guard Hive ritual sites. There is nothing living to the Shrieker, but neither are they mechanical constructs in a classical sense. They seem to be dead mass, animated by the arcane will of the Hive. When a Shrieker is broken, its Void charge rips free of the hull to seek vengeance. It lies dormant until provoked, where it will split into multiple pieces that float around a core.

Destiny 1
Closed Shriekers are impervious to attack, so one must approach a Shrieker to open it. However, Sleeper Simulant can destroy a closed Shrieker. To attack, it will periodically shoot a cluster of many simultaneous projectiles at the player until killed.

Destiny 2
Shriekers follow a new attack pattern, now firing a continuous spiraling stream of projectiles capable of rapidly shredding the player's health. The old cluster attack remains, but is used only occasionally.

Trivia
When a Shrieker is defeated it will release a final swarm of its explosive projectiles which will then track towards the Guardian that defeated it, making it deadly even in death.
