Strong

Strong is a super mutant and a possible companion in Fallout 4. He can be found locked up in a cell at the top of Trinity Tower along with his teacher, Rex Goodman, where the two have been imprisoned by other super mutants.

Background
A usual-looking super mutant, Strong seeks to find the "milk of human kindness". This is a line from the play Macbeth (Act 1:Scene 5), cited to him by Rex Goodman while trying to teach the super mutants about William Shakespeare's plays. Strong seems to have taken this metaphor a bit more literally and believes that if he can find the milk and drink it, it will gift super mutants the strength that have made humans successful. Strong is proficient with heavy weapons, like the missile launcher.

Effects of player's actions
The Sole Survivor can free Strong from his cell during Curtain Call. After completion of the quest, he becomes available as a companion.

Eventually as his approval of the Sole Survivor increases, he will admit that he has learned to respect the player character.

Finally, once he idolizes the Sole Survivor, he will tell he has made the decision to make the Sole Survivor his leader, and his Berserk perk will be given.

Approval

 * He likes it when the Sole Survivor steals.
 * He likes it when the Sole Survivor helps others.
 * He likes it when the Sole Survivor cannibalizes corpses.
 * He likes it when the Sole Survivor is in a confrontation and chooses an aggressive or violent option in dialogue over a peaceful or compromising resolution.
 * He likes when the Sole Survivor accepts less reputable quests such as securing chems (and dislikes asking for more money for such quests).
 * He loves it when the Sole Survivor murders people. Possibly also counts for killing enemies, even if the game doesn't tell anything about this (see Notes).

Disapproval

 * He dislikes when locks are picked.
 * He dislikes when terminals are hacked.
 * He dislikes the player character entering power armor.
 * He dislikes it when the Sole Survivor convinces people with charisma.
 * He dislikes the player speaking as the shroud
 * Strong dislikes when the Sole Survivor accepts more reputable quests (and likes asking for more money for such quests), such as the clearing the Boston Public Library for Daisy of Goodneighbor.
 * He hates it when the Sole Survivor joins the Brotherhood of Steel.
 * He hates it when the Sole Survivor brings the experimental serum to Virgil.

Appearances
Strong appears only in Fallout 4.

Bugs

 * If sending Strong to a settlement with 0 population, water, and food he will vanish from the game after a couple of days. The only way to fix is to summon him via console command.
 * A possible fix is to build food and water and then wait several days.
 * Another possible fix if a bed is not present is to build a bed then save and reload while away from the settlement (this was tested at the Red Rocket truck stop).
 * On some occasions, the message showing that Strong likes/dislikes this does not appear even when a certain amount of time for that action has past, thereby making it even more difficult to gain his Berserk perk.
