Lucy

Lucy is a witch who attends Cloud Tower and was Mirta's only friend while she was there.

Appearance
Unlike the rest of the students at Cloud Tower (and Alfea, and every other girl in the series for that matter), Lucy has an elongated face and sharp, angular features. She has a thin, bony figure and stooped shoulders. Her eyes are a pale green. Her jagged, dark green hair falls to her waist and her uneven bangs hang past her eyes in places.

Personality
Lucy, like most witches, she is basically rude and shows great hostility to fairies, but is still friends with Mirta, despite her leaving Cloud Tower. Unlike most of the witches however, she is much more insecure and cowardly (especially for being a prominent target of the Trix).

Her insecurity has led her to do rash things that either backfired against her (e.g. Lucy wanted to compete in the Miss Magix contest, and applies to the Trix for help but is betrayed by them while she is being crowned) to following the wrong crowd, often wanting to prove to others that she is amazing. She does have her moments of happiness however, especially when she spends time with Mirta and they enjoy their favorite pastimes together. Lucy can also be untrusting to others, in particular the Winx when they were at Cloud Tower assisting them in defending their codex.

As the series progressed, her self-esteem appears to have gotten better, she is capable of putting differences aside when present with a valid point and is proud of who she is. She shows (and comments) that not all witches are really bad like the Trix, and has expressed guilt and willingness to apologize.

Magical Adventure
She was seen at Alfea for their annual party, prior to the celebration, she and her fellow students enchanted the food, turning anyone who ate them into frogs. After plenty of fairies had turned into the frogs Lucy noticed her friend Mirta had not eaten any. She starts throwing the enchanted food at her in hopes of getting her turned into a frog. But, unlucky for her, Mirta was much quicker on her feet and ends up putting a piece of the spelled food into Lucy's mouth thus turning her to a frog. And, as her frog-self, she is spooked off by a bemused Mirta.

Season 2
Lucy makes her debut in the beginning half of Return of the Trix Girls, where she can be seen drinking as she sits by herself at a table watching the Trix storm off now that they have become the laughingstock of the whole party.

Later on, as the Trix express their frustration with the Winx, who they still cannot fully remember, Lucy knocks on their door and asks to be let in. When Stormy tries to shut her out, Lucy gets their attention by asking if they want to know why everyone is avoiding them like the plague.

Upon being let in, Lucy makes herself comfortable in the Trix's dorm and claims that they have already met, even if they cannot remember. She then reminds them of how they cannot remember anything farther than two months ago and asks if they feel like they were "just born yesterday." When Stormy insists that they lost their memories due to an illness, Lucy spills out the truth of what happened: that their amnesia was the cause of a spell that backfired and harmed them the most.

She goes on to explain that it was thanks to the Winx foiling their plans just like all the other times and, when Icy claims that they do not even know the Winx since she and her sisters only arrived recently, Lucy insists that the Trix know of the Winx all too well. She then starts recounting the Trix's past, starting from when they tried taking control of the Dragon's Flame and ending with their plot to use the "evil wind" to erase everyone's memories so that they could reintegrate into society.

Since their "evil wind" backfired and caused them to forget everything, the Trix were pardoned and everyone made a vow of secrecy to never remind them of their past misdeeds. When Icy asks why she went against this vow, Lucy claims that it is because she is would like to be honest with them as their "friend." She then reveals her desire to become a Trix witch only for her little plan to completely backfire. Enraged, the Trix kick Lucy out of their dorm, unable to believe the fact that were beaten over and over like complete losers by "stupid fairies" like the Winx.

Magical Abilities
Like all witches, her powers are derived from the negative aspects of magic. She can also shoot green energy beams that can burn her target and transform herself into snakes.

Lucy may know some basic, first-level spells that all witches can use, such as telekinesis, transmuting objects, and fixing minor messes. Like all witches, she can fly. In both "Betrayed!" and "Alfea Under Siege", Lucy demonstrated that she can shoot lightning from her hands, just like the rest of the witches. In said episode of season 1, Lucy has also been shown to create blue lighting, but this was only done once and the next time she does this the lightning is pink.

Trivia

 * Lucy is derived from the Latin names Lucia (feminine form) and Lucius (masculine form), meaning Light.
 * Lucy's facial features as well as her hairstyle are similar to those of the animated series X-Men: Evolution 's incarnation of the X-Men mutant Rogue from the Marvel Comics ' universe, and might have been inspired by her.
 * Lucy being a outcast who is a good person might also have been inspired by Rogue from X-Men: Evolution, who similarly starts as an outcast character who later becomes frie nds and later part of the X-Men team.
 * Lucy's hair is of the same shade of green as the top Rogue usually wears in X-Men: Evolution.
 * Lucy is visually similar to the Storm Harpies created by Stormy in " The Black Willow's Tears". This is either due to a character error or is an intentional pun fashioned by Stormy at Lucy's expense since Lucy (when hypnotized) was the one who informed Valtor that the Winx were going to Linphea to save Faragonda.
