1) Bloomix: I think Bloomix is the strongest transformation because it conducts the magic of the Dragon Flame with the Winx's magic itself. In Season 6, it 表示する how powerful Bloomix spells were.
2) Sirenix: Sirenix is a powerful transformation because it was a legendary transformation that could be earned only によって the Sirenix Quest. あなた also had to cautious and quick to earn it because magic could be stripped away または あなた could suffer under the Sirenix Quest. It is based upon the powerful element of water.
3) Enchantix: Enchantix was supposed to be the "Final Fairy Transformation", so it kind of signaled that it was a strong transformation. Once あなた had earned Enchanitx, あなた are able to obtain Fairy Dust. Fairy Dust had the ability to break dark spells. The attack/offensive/defense spells also appeared to be able to cause damage または protection.
4) Believix: Believix is able to help people overcome their fears and strengths. This power was also able to defeat the Wizards of the Black サークル, 円 (with the help of Nebula and Roxy). Still Believix is a major transformation to help people's hearts.
5) Harmonix: Harmonix improved the ability of the Winx によって helping them swim faster. It also was able to cause damage to the mutants and Tritannus when they used their spells to attack.
6) Magic Winx/Charmix: Magic Winx is a basic transformation. It is strong in its own ways, and the magic of this transformation allows the caster to use their strongest spell to appear (ex. Bloom and the Great Dragon).
7) Butterflix: It captures the essence of nature. With Nature's power, the Winx can use the force of nature to cause damage to the enemies. The only weak point is that they can't damage nature itself.
8) Sophix/Lovix: Sophix and Lovix are effective against the Guardian 妖精 of Earth. If they are powerful against the major fairies, they can be label as strong. A weak point is that this transformation can only be helpful with nature. It doesn't entirely defeat an enemy.
9) Mythix: Mythix was able to defeat the monsters of the Legendarium and Acheron. A very weak point of Mythix is that it is rendered useless towards the Winx since the Legendarium is closed up for good for now.
10) Tynix seems to be the weakest transformation because all of the spells are conducted in the mini-world. It may slow down time when the Winx go, but it had no use in the regular world. Due to the fact that the bracelets were 与えられた によって the Fairy Animals, Tynix has no purpose once the Fairy 動物 won't be with the Winx anymore.
According to me Mythix is the weakest as it only works in the lengdarium world and that to not very powerful. Then Charmix Tynix Butterflix Magic Winx Believix cause they first started firing spells in believix. Harmonix cause it works both underwater and outside. Sirenix because they behave like warrior fairies. Bloomix cause its the power of the dragon flame. Enchantix cause they've got awesome fairy dust.
For me its : Magic winx beginner level fairy original form Charmix same Mythix only for legendarium. Bloomix they aquired it so easily in the just the beginning episode 3 Tynix boring Butterflix not cool Harmonix fighting skills improved Sirenix they have to complete a quest to become warriors Enchantix it was to be the final transformation. Beleivix it got three sets of wings and powerful spells they used for the first time.
Weakest to strongest transformations (my opinion) 11.Mythix 10: Butterflix 9: Harmonix 8: Charmix 7: Onyrix 6: Dreamix 5: Sirenix 4: Believix 3: Tynix-Tynix could travel to a whole other world. 2: Bloomix-It holds the power of the dragon flame 1: Enchantix-It 発言しました “Maximum power” in both of the Enchantix songs and was 発言しました to be the final transformation.
