Strong (Companion)

Strong is a "different" supermutant, capable of reasoning and restraint. He can be found along with Rex Goodman on top of Trinity Tower during the quest Curtain Call. Strong is also probably the hardest companion to gain admiration from since he has a wide range of dislikes. If dismissed without assigning to a settlement, he can be found in the lobby of Trinity Tower.

Extra skill/ability

• Strong will occasionally give you raw meat when talked to. You can eat it as is or cook it via cooking station.
• Natural proficiency in heavy melee or ranged weapons.
• Has higher Defense and HP compared to all other companions.
• Ability to wear super mutant armors you can find in supermutant-held locations.
• Strong also has the highest weight carrying capacity among all companions

Approval

Saving and reloading after eating each corpse will allow you to "farm" affinity points from Strong)
• Accepting repeatable quests from Settlers and being "cocky" in conversations
• Violence and fighting

Disapproval

• Entering Power armor
• Roundabout and peaceful choices
• Lockpicking
