Sirenix was introduced in the fifth season of Winx Club, the Italian animated series created by Iginio Straffi, as the fairies' underwater transformation. Its song became one of the most remembered musical moments from that era, especially in the original Italian version quoted by fans. Clips of the sequence circulate on video platforms and soundboards as a nostalgic shorthand for magical transformations. The ocean-themed lyrics and soaring chorus keep it popular for edits long after the season aired, particularly among viewers who grew up watching the Winx fairies.

The Sirenix transformation song from Winx Club, featuring the Italian lyric about the ocean's power inside them, used for magical girl edits and reveals.
This clip is the Sirenix transformation theme from Winx Club, sung in Italian with the drawn-out call of Sirenix and the line about the force of the ocean being inside them. Bright synths, layered female vocals and a rising pop melody build as the fairies gain their underwater powers. It sounds triumphant, glittery and nostalgic, instantly signalling a power-up moment. For viewers who grew up with the series, the swell of the chorus feels like unlocking a new form, which is why the sound works so well as a celebratory reveal or glow-up cue.
