Dogmeat is a must - mention. His loyalty is unrivaled. He doesn't have complex motives like some humanoid companions, but his simple presence and the way he helps the player in combat and exploration tell a story of pure loyalty. And Curie. She starts as a simple caretaker - like robot but evolves into a complex synth with her own dreams and desires, which is really cool.
Codsworth has a very touching story. He's been alone for so long, waiting for the Sole Survivor, and his story is about that undying loyalty. Hancock also has a great story. He rules over Goodneighbor with his own style, and as a companion, his views on life as a ghoul and his interactions with other characters make for a really engaging story.
Wyll is an interesting companion. He made a pact with a devil, Mizora, in order to gain power to be a hero. His story is all about his attempts to redeem himself and break free from the devil's hold. His relationship with the other companions and his decisions based on his moral code are key parts of his story. Karlach is another great companion. She has a heart of gold despite being a tiefling. She escaped from the hells but is haunted by her past there and her time with Zariel. Her story is one of survival and finding a place in the world.
Well, for me, Sebille is a standout. Her journey from being a slave to seeking revenge is full of twists and turns. She has to face her own demons as well as external threats. Lohse's story of dealing with the demon possession is full of drama and emotion. And Fane, with his ancient knowledge, has a story that can change the perspective of the whole game world. His past experiences and his role in the current events of the game make his story one of the best.
Well, without more context, it's hard to be specific. But perhaps these are stories where the companions in Radiata have unique abilities that complement each other. For example, one might be a skilled archer, another a powerful mage, and they form an unbeatable team. They could go on quests to save the Radiata land from an evil sorcerer or some kind of natural disaster, and their bond is what makes their story great.
Sebille is another great one. Her story is like a journey of redemption in a way. Starting from her life as a slave, she's constantly evolving and learning about herself and the world around her. The choices you make with her really shape her story in different ways.
Wyll's story is quite good too. He made a pact with a devil to become a warlock. His journey of trying to break free from this pact while still using his powers for good is full of moral dilemmas. He has to deal with the consequences of his actions and his own sense of right and wrong, which makes his story really interesting.
One of the best stories is the main questline where you search for your son. It's filled with mystery, danger, and moral choices. You get to explore the post - apocalyptic world of Fallout 4 while on this personal mission. Another great story is that of the Minutemen. Rebuilding settlements and protecting the common folk gives a sense of purpose and there are many interesting characters involved in this storyline. And the Brotherhood of Steel story is also quite engaging as they bring their own ideology and goals to the wasteland.
A really cool story involves a cult - like group in Fallout 76. They had some strange beliefs and were causing trouble in the region. A group of players teamed up to take them down. The whole process was filled with intrigue, as they had to figure out the cult's plans and weaknesses. It was like a detective story within the post - apocalyptic setting.
I'd say Shadowheart is a must - mention. Her backstory is full of mystery. She has been sent on a mission by Shar, but as she progresses, she starts to question her faith and her role. Astarion's vampire nature gives his story a dark and alluring aspect. His struggle for freedom from Cazador is a central part of his story arc. And Gale, his connection to the goddess Mystra and his attempts to control his magic while dealing with his past mistakes make his story really captivating.
Piper is a great choice for the story. She's a journalist with a curious nature. She'll often comment on the events in the story, adding some interesting perspectives. And her personal quest also ties in well with the overall narrative of Fallout 4.
Gale's story is quite interesting too. His relationship with Mystra and his struggle with the dangerous magic item he has within him add depth to his character. His journey to either redeem himself or find a new path in life while dealing with the consequences of his past actions is a great part of the BG3 companion stories.
