Wendy Marvell

Wendy Marvell is a young female Dragon Slayer mage belonging to the Cait Shelter Guild. She learned her Dragon Slayer abilities from Grandine.

History
She was raised by the dragon Grandine for some time. However, one day Grandine suddenly disappeared and left Wendy alone at around the age of five. She ran into Gérard who allowed her to travel with him for a month, although they were both hopelessly lost anyway. One day Gérard (Or possibly Mystogan given the staff) uttered something known as "Anima" and deemed it too dangerous for Wendy to travel with him further. He left her in the care of a close guild, Cait Shelter, where she been ever since.

Tower of Paradise arc
She is first mentioned in a conversation between the dragons Igneel and Grandine in which the latter says a more "friendly relationship" could be established the next time she and Natsu Dragneel meet.

Oración Seis arc
Wendy is Cait Shelter's delegate sent to the alliance meeting of the Fairy Tail Guild, Lamia Scale Guild, and Blue Pegasus Guild along with the cat mage Charle; much to the shock of all there due to the fact that she is only a child. She tells the delegates there that although she has no particular combat prowess she is able in support magic. Natsu zones outs a bit once he sees her getting the feeling he knows her, but can't quite remember where. Soon the alliance sets off to find Oración Seis after being briefed about them and quickly find their target (or moreover they find them after the Blue Pegasus' airship is destroyed). Wendy quickly hides herself behind a rock and stays there for the duration of the battle as she watches the others get trounced by the Oración Seis. Just as the Oración Seis's leader Brain is about to finish them off he spots Wendy and halts his attack, suddenly shaken at the sight of her. Wendy and Happy (who was grabbed by mistake) are then kidnapped by Brain seconds later. Charle states that Wendy is the Dragon Slayer of the Sky and she can heal Erza Scarlet who had been poisoned by Cobra.

Later, Brain reveals her unique ability of healing to the others and has Racer bring a large coffin to her. Brain plans to use her healing magic to heal whatever was inside of that coffin but Wendy refused to help anyone that is "bad". The person in the coffin turned out to be no other than Gérard, who knows the location of Nirvana but is in his unconscious state. Gérard must be an important person to Wendy as she stated she owed him a debt and even went as far as saying that she loved him. Having internal conflicts of her and other people's perspective on Gérard as being good or evil, she received five minutes to decide. Natsu arrived at the scene with Charle only a moment too late as Gérard was revived. Wendy collapsed not too soon by exhaustion from healing him. Natsu tried attacking Gérard but was easily overwhelmed. Gérard then set his eyes on Brain and attacked him. Using this opportunity, Natsu took the unconscious Wendy along with Charle to heal Erza. They were intercepted by Racer, who was already having trouble with Gray. Racer tried taking them out but was stopped by Gray a second time.

Eventually Natsu rendezvous with Lucy Heartfilia and Hibiki Laytis. Natsu wakes Wendy up then begs her to save Erza. She gladly agrees and does so though still a little remorseful in reviving Gérard. She, along with everyone else, suddenly notice a pillar of light erupt from the ground and instantly realize Nirvana has been activated. After Nirvana was activated she is knocked out by Hibiki in order to prevent her from becoming evil (she blamed herself for resurrecting Gérard) due to Nirvana's influence.

Hibiki carries her as Lucy, Charle, Happy and he follows Natsu and Erza who are heading for Nirvana. However their stopped by Angel who attacks them, Hibiki is wounded and orders Charle to take Wendy away for fear of her getting recaptured. It is later shown that Wendy and Charle hide themselves for the time being, Wendy having regain consciousness though still feeling remorse for not being more useful. As Charle and she talk, Wendy reveals her acquaintance with Gérard and the rumors she heard about his Siegrain half. She however still believes Gérard (possibly a mistaken Mystogan) to be the kind young man she once knew. When Nirvana's second stage is activated, she and Charle are caught in when its legs appear from out of the ground. Charle carries away, and Wendy says they should head for Nirvana. As they land to take a rest, Wendy realizes that Nirvana might be heading toward Cait Shelter. With this, she goes to find Natsu and she cures him of poison and she uses a spell to temporarily cure his motion sickness.

Wendy still believes that its her fault that Nirvana got activated and thinks that Gérard might know something on how to stop it. So she tells the others that she has some clue and ran off. Both Wendy and Charle are looking for Gérard while reassuring herself of Nirvana's destination to Cait Shelter, but Charle is too exhausted to fly. So they continue on foot. Wendy does say that Gérard smells different from the one she knew before (which strongly indicates that it was Mystogan that she met). She sill believes in that Gérard is a good person and has never forgotten about him, and hopes that he is safe. Meanwhile in the next scene it shows him being defeated easily by Midnight.

Abilities
Sky Dragon Slayer: Wendy is the Dragon slayer of the Sky, which means that she has the same power as Natsu and Gajeel Redfox, but with the ability to manipulate air. As stated by Charle, Wendy can eat air, but can't heal as well in polluted areas. Her magic allows her to heal people from the most serious of injuries, even those caused by a dragon, allowing her to use even a kiss to heal other people and can even counteract other magic. However there seems to be a limit to how much she can use as she fainted no sooner then reviving Gérard and Erza


 * Troia: A type of healing magic sharped in the form of a ball which wendy used to heal Natsu's motion sickness.
