All Caste Jason Todd in HP

During the events of Under the Red Hood, the Batarang released by Batman slices Jason's throat unable to move, as Batman saves the Joker and Jason dies in the explosion. He transmigrates into an alternate DC universe where his mother, Catherine Todd, is a witch from Britain living luxuriously in Gotham.
The All - blades that are attached to his soul arrive with him. With a training "system" in tow, watch as Jason Todd takes on the duties of All Caste to eliminate evil both in DC and HP world.

DC AU, HP AU. I don't own DC, HP, or the cover image.
