The character appears to be an original creation for the TV show. However, **she may be a nod to little-known character [Yi Yang][1] of Earth-616**.

Yi Yang shares both the ethnicity AND the powers of Jiaying, as well as having a similar name. Like Daisy Johnson, Yi Yang was not an Inhuman in the comics but instead gained her abilities as the result of a chemical formula. In the case of Yi Yang, however, the character is not related to S.H.I.E.L.D. in any way, nor is she related to any of the other characters seen in the show. Still, she may be the inspiration for the character if nothing else.

Little is known about Yang - she claims to be over a thousand years old and was last seen as a member of the villainous Unkillables, which is a D-list team comprised of villains with healing factors or similar abilities that make them difficult to kill.
