Best Winx Club Sirenix transformations

Musa wins 70% of its duels and tops the Winx Club ranking ahead of Stella.

Musa dominates with 1361 ELO points, pulling 105 points clear of Stella in second place. This gap marks the sharpest divide in the ranking, suggesting fans view Musa's Sirenix transformation as decisively superior to the rest. Stella holds second with 1256 points across 73 duels, while Bloom lands in third with 1197 points despite matching Stella's duel count. The protagonist's middle placement surprises given her central role in the series, yet the data reflects pure aesthetic judgment on the underwater fairy forms. Flora and Aisha cluster close behind with 1183 and 1177 points respectively, separated by just 6 points after 80 and 84 duels. At the bottom, Tecna struggles with 1025 points and a 25% win rate across 57 duels, indicating the community finds her Sirenix design less compelling than her companions'.

How this ranking is computed

Every duel won lifts a contender and every loss drops them, by an amount that depends on the opponent's strength: beating the leader is worth more than beating the last. It is an ELO, the same principle as in chess. Duels are not drawn at random — an adaptive entropy sort puts the least predictable match-ups first, which settles the ranking far faster than a full round robin. A worldwide ranking is only published past 30 completed plays. Known limit: a contender who has faced few opponents keeps an approximate score, and the bottom of the table moves more than the podium.
