Iginio Straffi, creator of Winx Club (2004), wanted to make a "flesh and blood" version for years. As a cartoonist, he had never worked with live-action before. To prepare for the show, he worked as a producer on Nickelodeon's live-action series Club 57 (2019).
According to the production team, Fate: The Winx Saga will be targeted towards young adults and will be "edgier and darker than they (the older audience of Winx Club) can imagine after being used to the colorful world of the Winx."
Abigail Cowen (Bloom) and Danny Griffin (Sky) have been dating since 2021.
In the first episode, Terra mentions that she has a cousin named Flora. In the cartoon, Flora was the fairy with earth/plant-based powers.
Brian Young, a former writer for The Vampire Diaries (2009), is the creator and show-runner of Fate: The Winx Saga. According to an interview with The Guardian, Young chose to "ditch the look" of the cartoon Winx fairies; he said, "Look, again, I'm a massive manga anime fan... but nobody looks like that."
