If the witches of Madoka Magica infected every generic universe of any generic shounen anime such as Fairy Tail, Dragonball, Attack on Titan, One Piece.

The witches will not be at the same level of difficulty as the original, especially Walpurgisnacht. Each universe, the witches power levels will be either weaker or stronger than the original. such as if these witches were to infect the fairy tail universe, the normal witches will be at half dragon level. While the Walpurgisnacht in each universe will be 90 times more powerful than the final boss. Like in the Fairy Tail universe main story, the final boss is Acnologia, Walpurgis Night in that universe will be 90 times more powerful.


The witches' power levels are different for each respective Universe.
