So just doing a little bit of thinking and usual bits. Throwing around a few ideas and inquiries, this one spring to mind.
So image you will in the fan fiction My Little Dashie : As most of us know it's set in our reality about a man who finds Rainbow Dash and raises her until she is grown.
Now imagine say tweaking the story a bit that society is toleratent of a rainbow colored talking pegasus.
Now we interject more reality, considering that Hasbro has copyrighted the characters of My Little Pony, would that mean that they could physically take custody of Rainbow Dash?
