Maybe a story where the powers of Prototype are combined with the Sacred Gears in Highschool DxD. The main character could be a new transfer student who has a Sacred Gear that is somehow related to the Prototype virus, leading to all sorts of chaos and power struggles among the different factions.
One idea could be a character from Prototype having to adapt to the supernatural world of Highschool DxD. For example, Alex Mercer could end up at Kuoh Academy and have to deal with the devils and angels while also trying to figure out his own powers in this new context.

This enemy could be a new type of threat that neither the devils, angels, nor the Prototype - like being has faced before, forcing them to work together and learn from each other's strengths.
