Taking a break from season four…
The first people you’d think about if someone mentioned togetherness, magic, friendship, convergence, and power in the Winx Club series is, of course, the Winx. But those words apply to their nemeses The Trix as well, though the evil trio themselves would never admit it. Stormy tries to in “The Black Willow’s Tears” (S3, E12—Rai Eng title), but Icy and Darcy call her out for being sentimental. (Witches.) But she’s right—the Trix truly are best friends.
In the Rainbow English dub of the season one, they often refer to each other as “sister” (I don’t think they’re related—it might be a coven thing). Whatever they do, they do together—except when they’re fighting over their master. But just like the fairies (sometimes sooner than them), they manage to settle their differences and cooperate almost flawlessly again. They respect and accommodate for each other’s strengths and weaknesses. They also (usually) protect each other. And what about power convergence? That’s not only the Winx’s trick—The Trix master it before the Winx really know what it is, and in the last episode of season two, they even create something similar to the Winx’s “fighting Morphix doll” (“Win-x Together”: S2, E12—Rai Eng).
Of course, we know this is one club nobody else is likely to join. The Trix’s identity as a threesome is steeped in symbolism. Besides, who could possibly fill the role of the fourth “Trix?” And what would they call themselves then? The Quadrix?
