Working through my list of demigods since some things have changed (and I still haven't finished Heroes of Olympus series so it might also change again )
Also note, that some of these aren't expanded on in the demigod universe. I just tend to try and figure out what god/goddess parent or cabin a certain character might fit in with regardless if they're supposed to be for this universe. It's kinda like my liking of associating them with a certain element or bending type. =u=
I'll just put a * next to the ones who was originally meant for the universe or heavily influenced from it.
Apollo: *Wendy Dakota Rockefeller
Poseidon: *Francis Thames Aphrodite: Anastasia Hart Mint Jalloh
Hephaestus: *Penelope Kihike Marcos Hernandez Demeter: *Rosa Flores Yeon Sang-Min Hermes: *José García-Peña Rogelio Miranda (de Jesus) Hecate: Ayawa Baddoo Ares: Blythe Hayden Donatella Vidal Dionysus: Diego Kaan Jane Saint Christopher Hades: Isseti (who needs a last name at some point)
Hypnos OR Morpheus: *Milagros "Mila" Zapata Eris: Kajin Reznik Hudson Papandrea Huntress of Artemis: Esperanza Guerrero del Rosario
