Bloom's Origin: Planet Sparks / Planet Domino

Tecna's Origin: Third Vector of the Binary Galaxy (General) Techno Dust Fairyland / Planet Zenith
In the Welsh translation broadcast on S4C , Bloom is renamed Blodwyn , a literal Welsh translation, and Musa becomes Martha , presumably because the name Musa sounds very similar to the Welsh word mws , meaning stale or stinking. In the Italian version, Winx doesn't have a meaning and it's just a word Bloom made up. In the US version, it means magic. The Italian version has been dubbed into English (although that version does not see broadcast in many countries, other than Southeast Asia, due to the 4Kids version), and most other countries translate from that version, though some countries may use the 4Kids version.
Also, the original English version is ironically known as the UK version, but the UK is known to air the 4Kids version.
