—Radius Bone Jack
Radius Bone Jack, also known as Radius Bone or Captain Radius, is a mentioned character in Genshin Impact. She appears as a one-time enemy on Tete Isle, Easybreeze Holiday Resort, Natlan, taking the form of a Koholasaurus Warrior: Reefsplitter.
Profile
Radius Bone is the Captain of the Radius Bone Sailor Squad. Tecuhtli is also her subordinate.[1] She appears to be based in Nasha Town, and her crew is currently involved in a power struggle in the Nod-Krai underworld against Rekis (and possible others).[2]
Radius apparently owes certain "personal debts" to Rekis, and wants to contest his claims of "spine ownership." Rekis has attempted to leverage this to recruit her into his Asha trafficking scheme, but Radius refused, instead making efforts to disrupt Rekis's operation.[3]
It is unclear what Radius's fate is after the Traveler defeats her in combat.
