Apex

Apex is an hostile Typhon encountered on Talos I  during Prey (2017).

Overview
The typhon Apex is the largest Typhon observed so far, and attacks and begins consuming the Talos I space station near the end of Prey. The Apex is most likely summoned by the Coral structure constructed by the Typhon, which Alex Yu claims is a method of communication for the Typhon. The Apex cannot be killed directly by Morgan but it's tendrils can be destroyed, even though they will return shortly. The process of creating an Apex is unknown. Capabilities of an Apex are unknown or unclear. It is possible that an Apex can create other Typhon organisms in a manner similar to Weavers.

There is only two ways to defeat Apex which the choice lies on player itself, destroying Talos I through self-destruct which results in destroying the Apex as well or installing the Nullwave on the Heart of Coral to defeat the Apex without destroying Talos I.

Trivia
