This group is based around a thought that came to me.
What if there were ponies who felt as if they were born in the wrong body.
I don't mean wrong gender as there are already plenty of groups for that ,what I mean is that they feel they were born as ether the wrong tribe or species ,such as a unicorn who feels she should have been a earth pony or a Pegasus thinking she should have been a zebra.
I have dubbed this SDD or species displacement disorder much like how there is the real life gender displacement disorder.
