Phog Christoph (Japanese: フォグ・クリストフ, Fogu Kurisutofu; English dub: /ˈfɔːɡ ˈkrɪsˌtɔːf/) is a recruitable playable character in Xenoblade Chronicles X. He is a Prospector and a member of the private military organization BLADE. He is Frye's younger brother.


Phog is a human with blue eyes and short blond hair, which conceals his right eye.


Phog is an awkward, quiet man who values his time alone. He is known to frequently space out, or have a foggy head, and can often be forgetful. It is revealed in Animal Lover that he is deathly afraid of cats, as he says they do not like him. He and his older brother Frye have a troubled relationship, which was caused when their father sacrificed his position on the White Whale for a younger individual. Frye grew to resent his brother for accepting and understanding their father's decision when he could not, but the two later reconciled their relationship and began to comprehend each others' feelings. It is revealed then that the two still care for one another deeply, and begin to become close once more.



Phog is located near Deliverance Park in the Residential District of New Los Angeles.


Phog can be recruited after completing Foggy Dilemma.

Main story

Main article: Xenoblade Chronicles X (plot)

Like most recruitable characters, Phog does not play a large role in the main story. He does, however, appear in the ending credits scene where he can be seen struggling to do push-ups unlike other fellow BLADEs.


  • In the Japanese version, Phog Christoph is labeled with his full name. This was also the case in the unfinished localization shown during Treehouse Live presentation at E3 2015. During his fifth heart-to-heart he says he is part of the Christoph family.
  • Due to Phog's relationship with Frye, the two cannot be in the same party once they are first unlocked. This can only be fixed by completing Blitzkrieg.
