Spoiler for Interesting thing about Shrade:

He call everybody Shinyuu which amounts to Friend. Apollonius/Apollo kept calling all his teammates Tomo, friends.

I'm not saying he's Apollo but maybe parts of his previous incarnation certainly remember Apollo's trait.

Spoiler for On Mykage and Fudo:

They've known each in each incarnation. Brings to question who is Mykage.

I don't think we are dealing with Toma here. It is likely Elder Angel Johannes Fudo's opposite number in Aquarion.

Johannes was the leader of the Shadow Angels. In Aquarion TV Johannes was absorbed by the Tree of Life. In the OVA he was already frozen but conscious. Something went wrong with Toma's plan instead of being gods the Shadow Angels were further sealed by the dimensional freezing effects of Apollo, Silvia and Reika's union while destroying the world.
