Warning: This fic contains ponies with modern tech, for those of you who dont like that.

Alex Mercer saved Manhattan by bringing the nuclear bomb to the ocean, but when it detonated, Alex's instincts took over and sent him into an animalistic rage. When he wakes up, he finds things have changed. A lot.
Humanity is missing and ponies rule the world along with a few other species in their shadow.
Alex will have to adapt to the new world that moved on without him. He will succeed. Besides, it is what he does best.
