Simple rundown:
Hades: Fluttershy -> Hadeshy
Why? Cause Hades singing voice is very similar to Flutterguy so… yeah. Plus, I plan on making Hadeshy as awesome as Hades.
Orpheus: Twilight Sparkle -> Orpheus Sparkle
Idk honestly, I just thought Two would be a good fit for him.
Hermes: Applejack -> Hermejack
Who else would fit as the voice of reason in this story?
More to come later.
