General Jeremiah of the USSCSO, or United States Space Corps Special Ops, died.
Of course, dying and meeting a strange woman who offers you a gun like no other is weird enough, but apparently, she was unable to regenerate him properly. Now he's found himself in the middle of a strange land filled with people who look quite a lot like the Japanese Korean Union's animation and drawings. These 'ponies' as they call themselves are humans with ears of ponies. Some have wings and some have horns. These other appendages vary in color but otherwise, they look normal.
Another thing. Landing in the middle of the enemies meeting and decking Chrysalis in the face? Probably not a good choice. Nor was the dehorning of Sombra and the castration of Tirek. Of course, when you're a USSC Special Op, you tend have bad luck, but you get used to these things and training makes you able to escape extreme situations.
