I'm hoping then they expand on his Angelic powers and what that portains to his Trigger form...because as of yet, most of all the focus was on his demonic blood, with little really given in terms of what Eva being an angel did for his true form, other than being fluff background info that didn't change a while lot.
No one is a bigger fan of the game than I... but they could have just made Eva a
human leader of a rebellion, while still relegating the "Three Stances".
Human: Rebellion
Demon: Arbiter/Eryx/Red Yamato Combos
Hybrid: Osiris/Aquila/Blue Yamato Combos
Instead of this unnecessary Angel backstory, Eva could have made the "Initial Form" (slightly magically enhanced to slay demons) of the "Rebellion", then after meeting Sparda she gives the sword to him.
Edit: I'm going to keep this idea with me. And save it for the next inevitable reboot. :troll:
He then fuses his demonic energy with Eva's protective love of her children and the human race, and then Sparda could have fused the Rebellion with Dante, after that.
That wouldn't have made Rebellion a "hybrid" weapon though. It would have initially have been a human weapon, built to fight for and protect mankind.
The "hybrid" weapons would have been the weapons Sparda made after that. It was a while before Mundus imprisoned him (seven years, give or take), so he could have made them in that time period.
