Welcome to a new installment of "Makes Sense and Doesn't"

On this picture we have a ponified Starfire, and I am having a polarized opinion on her ponification.

Why it makes sense for Star to be an alicorn?

Well, because she is a princess of Tamaran, that's why

Why it doesn't?

My logic dictates: "In Equestria, if you are a pony with a functioning horn, you can do all kinds of magic with it." When it comes to Star, it only makes sense for her to sport a horn to

...and that's pretty much it. In her world she can only do that (apart from any other physical stuff). In Equestria she would have to be able to do more as an alicorn: move objects, cast spells, etc. That isn't really her thing now, is it? I believe there's somepony else whose schtick that would be: a certain friend of Star's.

Which is why I personally see her more like a pegasus. She would still be able to throw starbolts with her hooves. It would just be an unusual (for Equestrian standards) magic, but much more plausible.
