I think it's super sad how few ‘magical creatures’ there are in Winx apart from fairies, pixies and witches, or how little they are used. The teachers are diverse, and I really like that. But I just wish that it could've been explored a bit more.
Especially talking about planets and their inhabitants. I am not sure if it's still in my drafts or if I ever posted how I would like for them to be more unique in their appearance, and perhaps have special traits/marks/whatever.
Anyway, I think the best way would've been to use the specialists to showcase different magical beings/species. Let's talk about it.
Helia, you beautiful man. I saw fairy Helia already and believe it's not a novel concept but it's an amazing one, especially considering we meet no male fairy but see them on Domino / Sparx (if I remember it correctly...?). He could be a fairy of creation! Similar to Flora and her natural powers, while maintaining his artistic spirit. It would even be funnier if Saladin was a fairy too but still is the headmaster of the Red Fountain.
Alternatively, Helia could be an elf. Young Saladin resembles Palladium a bit and Helia has these typical male elf features if we are honest. He would be connected to magic still. Potentially be a Wood or High Elf!
Last but not least: A merman. I think it's the long hair mainly but I think he just fits the vibe of a mythical creature with a connection to nature.
Riven, my prince of darkness. My first thought is and always will be that he could've been a vampire. It's basic but vampires are iconic and could pair so well with Darcy - mental manipulation, dark powers, control of the shadows. I do not fuck with Winx vampires though. I have not a favourite vampire system but you best believe he gets the advantages while having no disadvantages.
One could object that vampires do not really fit the aesthetic and vibe of Winx. I agree. Riven could be a wizard too or have magical powers fitting the vibe of an arcane trickster. But even better would be something draconic. He got that temper, the vibe and could have his own fiery powers.
Sky, literal king. One could have thought that Riven would be a wizard but no, it's Sky! Listen, I think Eraklyon hates witches and had their own trials and such. What would be more shocking than their own prince being a wizard! Wizard would mean the male version of witch here. Erendor seems like the type to have an affair or Samara is a secret witch! The potential...
It also adds spice to Bloom's and Sky's relationship, seeing that wizards sorcerers hunted Earth Fairies, which Bloom could qualify as. Like not really but maybe yes. It's complicated.
I do not see Sky as something else except maybe a werewolf as the contrast to Riven's vampire but again, werewolves do not really fit the vibe - do they?
Brandon, the knight in shining armour. To be honest, I do not see Brandon being anything else than "human". Maybe a Paladin? He could even be a winged one like Avalon. The wings could be foldable.
If Sky were a werewolf, Brandon would be one too. They seem like two boys who play as pups and then grow up to be pack leaders or something.
I really love Brandon and I hope nobody thinks I gave him no thought because I did. I just really like him as he is and there was no mythical creature that I would need to see in the Winx.
Aside from Helia, I could also see Timmy being a fey-like creature, for example fairy, elf, leprechaun. First, I thought of a dwarf though. They are commonly presented as skilled craftsmen. He doesn't fit the look of a stereotypical dwarf though and I am not talking height (smol king Timmy would rule), so he could be like the one breaking tradition: becoming a specialist, pursuing a fairy (from Zenith!) and such.
From my point of view, Timmy could be an elf as well! It would be a great way to explore the difference between elves. I see him with magical powers and how he at first is clumsy with them but growing confident as person, he develops them more.
Nabu, our favourite alive husband. Strictly speaking, Nabu is not a specialist, but I will involve him anyway! He's a wizard, that's a fact. But he's also allowed to explore his possibilities. Obviously, of course: merman.
He would still have magical powers, but he would also be a beautiful merman with a gorgeous tail.
Actually, I like him being a wizard very much. I just really would've loved to see mermen before Season 5.
I am thinking about writing something that could explore this but knowing me, I never publish it. Anyway, this is all just ranting and imagining. You can happily share your opinion or protest mine or whatever!
