In Netflix’s “Jupiter’s Legacy,” Raikou discovers Walter’s scheme for the Utopian and the Union. She then decides to try to blackmail him over what she knows, but this proves to be a fatal mistake. Like her father, Raikou has incredible psychic abilities, but Walter makes it known that the two are still on different levels, as their final conversation is ultimately nothing but a mental construct created by the elder psychic. Walter kills Raikou inside the construct, then murders her in the real world.
In “Jupiter’s Legacy Vol. 2” #2, Raikou is still ultimately brought down — but not by her father. In the issue, the former super criminal Repro has been busted out and is tasked with using his ability of power mimicry to take Raikou’s psychic powers. He does just that by mentally incapacitating her after trapping her mind in a psychic construct. The comic implies that Raikou is left alive, but in a coma-like status.
Raikou’s appearance in the Netflix series was already a shock since she doesn’t appear in the comics until much later. Her surprising death seemed final in the show, but if we’ve learned anything from comic books, death is rarely ever the end for a character.
