Ingrid first debuted in Capcom Fighting Evolution and next appeared in Street Fighter Alpha 3 MAX. She also goes by the alias "Eternal Goddess". In the cancelled Capcom Fighting All-Stars, she had the nickname "Eternal Ray" (most likely relating to a ray of sunshine, given her attack theme).
Little of anything is known about Ingrid. The PSP version of Street Fighter Alpha 3 gives away some possibilities about her true origins. Apparently, her source of power is derived from Psycho Power, however, it is unknown if her power is purely evil like that of M. Bison or converted into something similar to Rose's Soul Power. Ingrid also claims that she is the true bearer of what is called "Psycho Power", as she constantly tells Bison that Psycho Power is "her power" and that Bison has stolen some of it. It seems that her power is so intense that if given the chance, she could actually break Ryu's madness if he ever succumbs to the evil of Satsui no Hadou.
Ingrid also possesses psychic abilities similar to Rose, as she addressed Ryu and Rose by name even though both never revealed their names to her. Rose, on the other hand, cannot look into Ingrid's future as she did with other Street Fighters. Also, there is a possibility that Ingrid can travel through time, as she mentions heading to the year 201X and seeing that Ryu has somehow become a monk.
The validity of her story is under heavy dispute, given how improbable it is and how poorly it fits in with the rest of the story (she flies off with the monument that's still present in Sagat's stage in Street Fighter II, and Charlie is officially the one to have killed Bison). Also, her claim to be more powerful than Rose or Bison contradicts much of Bison's displayed power in the Street Fighter canon. Details about her character in Capcom Fighting All-Stars are sketchy, other than she is the "Sun Goddess" and, unlike the other characters specific to the game, she was born with her powers. She has one of the codes to disable Death's bomb threatening Metro City ("Isis").
