Taliba is a double major who temporarily moved to Ponyville with her younger adopted brother, Spencer, to work on her University thesis: The Psychological, Sociological, and Societal Climate of a Small Town. However, she got a little more than she planned when she met a few of the other residents of the town

Finally finished this thing after 2+ weeks or so, but here you have it. Its the human mane 6 plus Spike where no one is white.

From Left to Right, their human name (race):

Leigha (Laotian), Flower Petal (Puerto-rican/White), Paisley (Black), Spencer (Black/Vietnamese), Taliba (Pakistani), Rajni (Indian), and Abigail (Mexican/Black)

They also have different sexual and romantic orientations not listed here. They do all identify as women (disregarding Spencer), since the show itself is about women and girl love and all that, but only half of them are cis.
