is hela loki's daughter in the comics
Hela (comics) Hela was born in Jotunheim, the land of the giants. She is the child of Loki (albeit a different incarnation[1] who died during a previous Asgardian Ragnarok) and the giantess Angrboða. When she came of age, Odin appointed her as the Goddess of the Dead, giving her rulership over the dead in the realms of Hel and Niflheim.
Io (mythology) Io was a priestess of the Goddess Hera in Argos,[5][16] whose cult her father Inachus was supposed to have introduced to Argos.[5] Zeus noticed Io, a mortal woman, and lusted after her. In the version of the myth told in Prometheus Bound she initially rejected Zeus' advances, until her father threw her out of his house on the advice of oracles.[17] According to some stories, Zeus then turned Io into a heifer in order to hide her from his wife;[5] others maintain that Hera herself transformed Io.[17][18]
