Jakob

Jakob ​is a playable character from Fire Emblem Fates. He will be the Avatar's ally regardless of their route, but will join later than usual if the Avatar is male.

Profile
Jakob is a butler who serves the Avatar in the Kingdom of Nohr. Although born into aristocracy, Jakob lost connections with both of his parents, a fact that, according to his supports with Azura, stems from them never loving him and forging happy memories with him. Electing to follow the Avatar regardless of the choice that they make, Jakob attributes this to the kindness and compassion that they displayed towards him when he was alienated during his induction into the service of the Nohrian royalty. If he achieves an S-Support, Jakob will have a son named Dwyer.

If the Avatar is male, Jakob will remain in the Northern Fortress with Flora. At the end of Chapter 15 of ​Birthright, ​Conquest, and ​Revelation, Jakob will eventually find the Avatar's My Castle and promptly joins their cause.

In the case of the female Avatar, he is more involved with the first few chapters.
