amy (madoka magica)
A stray, black cat found by Kaname Madoka and later Akemi Homura.
While it makes its first appearance in the OP of Mahou Shoujo Madoka Magica, it isn't until the drama CD released when the series was over that it was formally introduced.
In some of the previous timelines, Madoka's magical girl wish is for it to avoid being run over by a car.
