Ok, like I already said. Disney use exactly the same faries in their diffrents movies or series, the difference is how this fairies will be their presentation or image. Everybody knows who is the Fairy Godmother, don't they? If you don't, get out here and watch Cindirella please.

Well, actually Disney decide only to recreate their old movies and make it in live action, as we can see.

So my point is, although Disney use the same character, we can identificate so many versions of them. (like Tinkerbell) But with other fairies, like Knotgrass, Thistlewit and Flittle, there are the famous faries from Aurora's story, and a fact that maybe you miss, Maleficent was a fairy too. This same characters appear in Princess Sofia, they teach all the little princess about how to be a princess.
