This is the first daughter of Twilight and Flash that I invented before
But at one point I thought that her colors are very suitable for my zodiac sign. So she will be my ponysona pegasus
Her talent will be related to psychology

Or maybe I'll leave her as an alicorn. But she's not a princess. There were rumors (I don't know how true this is) that Lauren Faust wanted to make a separate race for the alicorns.
If this were the case, then most likely unisus would be just as mortal as ordinary ponies. They would have magic like unicorns, fly like pegasus, and be strong like earth ponies.
But they would have half as much magical energy. They would have to put in more effort to fly. And, most likely, their strength would be half that of earth ponies. They would have all the talents of the races, but half less than each of them
