X6-88



X6-88 is a synth character appearing in Fallout 4, and a possible companion.

Background
A highly advanced synth, X6-88 is an Institute Courser, designed for high-risk assault and retrieval operations above ground. X6 is very capable at engaging enemies at range, and is equally capable of direct assault and more subtle approaches.

X6-88 is first seen by the Sole Survivor inside of Kellogg's memories, giving the merc a mission to hunt down Virgil - and most importantly, take the Sole Survivor's son to the Institute itself via teleport.

Shortly after arriving at the Institute, Father tasks the Sole Survivor with helping to retrieve the leader of a band of Raiders, a mind-wiped runaway synth. X6-88 is the Courser dispatched to aid in this task, and a short while after the incident is resolved, becomes available as a companion for the Sole Survivor.
