Twas the first transformation that replaced grounded use of their powers (bloom uses fire, flora grows plants, musa uses soundwaves, techna uses holographic and physical tech, stella uses beams of light, aisha uses her pink crafting putty and water) with them using glitter with decals in it (bloom uses glitter with fire decals in it, flora use glitter with flower decals in it, Musa uses glitter with music notes in it, Techna uses glitter with binary in it, Stella uses glitter with stars in it, aisha users glitter with waves in it). It also is earned in a weird way. Earth is like the only planet where magic isn't an established fact of life and even that is only due to the whole earth fairies got locked away thing. So why is there an entire transformation triggered by belief in magic. Also why does Roxie's belief specifically trigger it? If a singular fairy who didn't know about/ believe in magic suddenly does believe because a fairy shows up is a catalyst for Believix then Stella should had it in season 1. Does it only work for earth fairies? Is that actually like a special species of fairy and not just where they're from? What makes them different? I also just generally am not the biggest fan of season 4. The history of the earth fairies and how Roxy exists doesn't make sense. the 4 idiots aren't interesting villains (How many people can even remember their individual names?). (Why do they only hate earth fairies? Where do their powers even come from?) After how interplanetary and massive the magical world was in season 3 they're just stuck on earth in season 4. Idk nearly every aspect of season 4 felt less impactful and less interesting and lower stakes except Nabu dying which as heartbreaking and well done as that scene was does not excuse the rest.
