What could be

I felt like drawing Hare as something different again. So I made a what if scenario

The Mad Hatter, an experimenter in both science and magic, tried to create a perfect being made from the DNA of the Mock Turtle, Jabberwock, Gryphon, and DorMouse. This time, his 'safetynet' did not work, and paid a price.

The March Hare had just walked into Hatter's lab to see a large grey beast and the clothes of Hatter lying on the floor. Hare's already fragile psyche finally snapped, and in a fit of her evolved madness, attacked the beast. As she fought and the beast avoiding her for dear life, potions and other experimental items fell and exploded on Hare. The result was a taller, stronger, and more powerful Hare.

She spared the beast for unknown reason, and soon the beast became like a pet to her, aiding her and following her every order. Her heartbroken state led her to a mad lust for power, taking the throne from the White Queen first. As she tried to acquire the other two thrones, she decided to kill those she saw as a threat, the first was Cheshire Cat.

With her size and strength, the aid of her beast pet, as well as her bloodline allowing her to wield Vorpal, she quickly disposed of all threats such as the Jabberwock, Mock Turtle, Gryphon, and Alan. As she finally seized power of all Wonderland, a crown was given to her. Due to her size, it was crafted into a bracelet. Known to keep a oddly designed top hat near her at all times, she says its "A reminder of lost love".

As for the beast, no one knows why its so loyal to her, no matter how much Hare abuses it for killing Hatter, perhaps its grateful to her for sparing its life, what the case may be it is loyal to her till the day it dies.
