who is the most powerful trix and why?

I think Icy because she is the one that everyone is most afraid of, so she's powerful in the social world, and she has powerful magic. BUT i think Stormy might have the most powerful attacks if her powers were put to full use BECAUSE she can do tornadoes and stuff like that.

i think icy is the most powerful because she seems to have the most moves and they are very strong.
also if winx wasnt a childrens show there are quite a few ways for icy to kill someone if she wanted.

icy might be scary to others and has nice ice attacks but shes not the most powerful and neither is stormy thanx to her not thinking be4 she acts she messes things up alot and she does have wicked storms but darcy can hyponotize almost anything to do her evil bidding while she can make ppl blind and hit them with dark energy magic shes not just an illusionist shes awsome

I think Stormy because she can do any storm she wants to meanwhile Icy can only do ice attacks and Darcy can only do confusion attacks.

I think darcy is the most powerful she is the witch 또는 퀸 of darkness 당신 may say as she an hypnotise 또는 make magical shields . though Icy is the eldest her attacks and speed comes slowy .so darcy is my fav and also my answer

I say it's icy. Everyone's afraid of her as if she was going to rip their heads right of their body while the 요정 always defeat Darcy and stormy.
