The season 5 two-part finale for My Little Pony Friendship is Magic, as represented by The Cutie Re-Mark - Part 1 and The Cutie Re-Mark - Part 2 revealed two surprises about Starlight Glimmer.

First of all, she turns good, like Discord and Sunset Shimmer (see My Little Pony Equestria Girls and it's sequels), and unlike King Sombra, Queen Chrysalis, and Lord Tirek.

It also reminds one of Anakin Skywalker/Darth Vader from the Star Wars movies.

The second thing about Starlight was her ability to fly using magic. She is more adept at Magic than the the vast majority of unicorns, and at least an even match magically with the Alicorns and Star Swirl the Bearded.

Although never mentioned in the show, I speculate whether Starlight Glimmer might be partially descended from pegasi.

Almost makes me want to see Dr. Hooves and Derpy travel through time and space in a machine similar to that of a certain Time Lord's TARDIS from that well-known British sci-fi TV series.
