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.

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. Completing quest Mankind-Redefined makes him available as a companion for the Sole Survivor. He can be found at Synth Retention Bureau

Effects of player's actions
When getting the max approval he will give you the Shield Harmonics Perk which gives you 20 Energy Resistance

Bugs

 * If X6-88 falls into the water in Libertalia, he won't be able to interact with the player character and would not leave the water. This can be fixed by shooting him several times.
 * If X6-88 is downed after defeating the raiders he may not be able to show up at the Sole Survivor's quarters.
 * When commanding X6-88 to travel to a settlement while the player is in the Institute, he may disappear. When using the console to teleport the player to him via the player.moveto command, th player gets teleported to the Institute but X6 does not appear. To prevent this simply dismiss him outside the Institute.
 * Even after the player has destroyed the Institute, X6-88 still can be found near the Nordhagen Beach settlement and still can be recruited as a companion. Moreover, dismissing him will simply make him teleport back to the Institute SRB as if it is not destroyed.
 * X6-88 may continue following the player even when dismissed or replaced with another follower. This prevents all interaction with The Railroad. Fix is unknown.
 * For some reason once you are able to recruit X6-88, he will be no where in the institute. You can find him between SW of Libertalia and NE of Nordhagen Beach, by a shored boat.


 * If X6-88 is your companion when you board the Vertibird for Spoils of War and become enemies with the Institute, X6-88 will fall off the Prydwen, become hostile, and become invulnerable. This will become an issue after the quest completes, as he remains by Boston Airport and will distract all troops (even Liberty Prime) and you will not be able to continue.
