Red Vs Blue Xover!

Church, the Alpha, was fairly sure he would die when he went to confront the Meta. Dead or not, he didn't expect to wake up in a forest, and not as a horse. A horse with a horn, wings, modified armor, and mounted firearms- but still a horse. Because he refused to call himself a pony, no matter what the locals said or how much Tex teased him! Now he just has to try to save his fractured mind. The AIs, luckily or not, are there to help him as they explore this new world.

Meanwhile, his loud and painful(for him) entrance into their world has brought a great amount of attention to the mysterious being that is now wandering through Equestria. The ponies best tread carefully. After all, the Alpha's "pack" can be protective.

May be Harem/Marem/Herd.

PS The Dark tag is mainly for Alpha Church's canon back story.
