Before the Curse
At some point, Mulan joins Prince Phillip on his journey to awaken Princess Aurora. She was journeying with Phillip when the Dark Curse was cast by Queen Regina, however, a small area was spared from the Curse, merely freezing the people there for 28 years. When Emma Swan broke the Curse in Storybrooke, time resumed, and Mulan and Phillip were able to continue with their journey.

Season 2
Prince Phillip and Mulan are able to find the former's beloved princess, Aurora, sleeping inside a gazebo on her palace, under the effects of the sleeping curse Maleficent cast upon her. Phillip awakens her with the kiss of true love, and they are overjoyed to find themselves back in each others company. However, their happiness is short-lived, for they are soon attacked by a Wraith, a soul-sucking creature, that somehow makes it to their land and marks Phillip. The latter keeps this a secret from his traveling companions, so as to not worry them, but the two women are able to track him down just in time to witness his soul being taken by the dark creature. They mourn his loss and Mulan tells Aurora the truth that Phillip wanted to withhold from her: their land was ravaged by the Dark Curse, enacted by Queen Regina, and most of its inhabitants disappeared into another realm, but for some reason that part of the land was spared and they were frozen in time for 28 years until something broke the curse and they were able to continue their quest to find Aurora. They then notice something, coming from the rubble from which the Wraith had previously emerged. Mulan removes the wreckage and they find Emma Swan and Mary Margaret Blanchard, who came from Storybrooke via a magic portal, and are now unconscious. The warrior and the princess are therefore led to believe that these two women are responsible for the death of their beloved prince...

Mulan and Aurora are riding their horses along a coastline with Snow and Emma tied up, following behind them on foot. They soon stop as they arrive somewhere, so Snow asks what the place is. Mulan tells them it is their home. A while later, when they arrive at the "home", the four girls walk through the camp, and there is many more people there, shocked to see Snow and Emma, mainly because of what they are wearing. Emma states it's like the people are refugees, so Mulan snaps that they are survivors. With that, Snow kicks the princess in the stomach and calls out for Emma to escape. They both run away, but Snow is knocked unconscious when Mulan throws a sling at her. Emma goes back to help her mother and then the warrior orders for them to be thrown into "the pit".

When Lancelot releases Emma and Snow from captivity, Mulan and Aurora watch from afar. The princess is angered, claiming they were responsible for Phillip's death, and she says she wants justice. Mulan demands the princess not to confuse justice with vengeance. Later, the warrior assists Emma and Snow on their journey to find a portal to Storybrooke. She gives Emma and Snow the choice of one weapon to take. When Emma seems to be taking the situation too lightly, Mulan warns her of how dangerous an Ogre is. Aurora follows them and attacks Snow White with a knife, however, she defends herself and pins the princess to the ground. Mulan pulls Snow off the princess, stating she'll sort the situation out. However, Emma soon intervenes and fires her gun into the air, alerting an Ogre. They all flee and Emma is nearly killed. After the Ogre is killed by Snow, they continue their journey to the royal castle. Mulan and Aurora stand guard outside, but when Cora revealing to have been in the guise of Lancelot the whole time, Mulan fights against her, saving Emma's life. When the portal to Storybrooke is destroyed, both Mulan and Aurora promise to help the mother and daughter get back to their family.

Emma, Snow, Mulan and Aurora return to the safe haven to find that Cora has murdered all of its inhabitants, by ripping their hearts out. However, they find a man - Killian Jones - alive, hiding beneath the corpses, who claims to have survived the attack. Mulan confirms that he was a blacksmith who joined their camp a few months prior. Emma is suspicious of the man and uses her perceptive gift to try and see if he is lying to them, and is able to tell that he is. Therefore, the women tie him to a tree and demand that he tell them his true intentions, under the threat of leaving him to be eaten by the ogres. However, Killian comes clean: he reveals himself to be the famed Captain Hook, and tells them that Cora requested his help, by having him earn the ladies' trust and find out everything he could about Storybrooke, so that she didn't have any surprises when she finally got there. He then reveals that the magic of the burnt wardrobe remains, and with the use of a magical compass that Cora seeks, they might just be able to make it to Emma's land. Hook then offers his assistance, the same way he did to Cora: he'll help them get the compass. They untie him, and let him tag along. Emma and Mary Margaret acknowledge that he is probably setting them up to take a fall, but this way they can stay one step ahead at all times. Killian brings them to a gigantic beanstalk that leads all the way to the clouds, and reveals that the compass is up there.

At the base of the beanstalk, when the four girls argue over who should be the one to climb up with Killian, Mulan insists she should go as she is the most skilled warrior. However, Emma overrules Mulan and takes her aside before climbing. She asks Mulan to cut down the beanstalk if she doesn't return within ten hours and to make sure Snow White gets back to Storybrooke. Mulan agrees, and then provides Emma with ground poppy in order to knock the Giant unconscious. After Emma and Killian begin their climb up the beanstalk, Mulan draws a line in the sand and places a stick in the sand at the end, saying to the other two women it is a way to keep track of the watches each of them should have. When Emma has been gone for ten hours, Mulan strikes a heavy blow to the beanstalk, but it tackled by an infuriated Snow who demands to know what she's doing. Mulan states that it is her daughter's wish. Just then, Emma jumps off the beanstalk, so Mulan does not need to cut the beanstalk down.

Mulan later announces to Emma that she may have some ideas as to where Cora is hiding. Emma goes to find Snow so they can discuss them together.

Origins

The poem, The Ballad of Mulan (木蘭辭 Mùlán Tzú), frequently shortened to Mulan, which was publicized in the sixth century, is an ancient Chinese poem in Southern and Northern Dynasties, detailing the story of Huā Mùlán (花木蘭). There are many adaptations of the story, the most popular - and the one followed closely by Once Upon a Time - being the 1998 film adapation by Walt Disney Animation Studios. The general story is during a time of war in China, a young woman named Hua Mulan sees that her father has been conscripted into the army. Having no older brothers, she decides to dress as a man and goes to war in his place. She spends more than ten years fighting alongside other male soldiers. Later, the emperor offers her a government post, but she turns it down saying that she would prefer to return home and see her family. At the end of the poem, Mulan finally reveals her female identity to her army comrades, who are shocked to see her as a woman.
