With the Oración Seis defeated, Lucy then heads back to Fairy Tail with her companions and Wendy. She is as equally shocked as Wendy when a loud bell in Magnolia chimes, and it is revealed that Gildarts has returned. Lucy tells Wendy a little bit about him, saying that Gildarts is supposedly the most powerful mage in Fairy Tail and that she had never seen him before.
As Mystogan reveals the truth about Anima to both Wendy and Charle, she is seen at the guild wondering when the rain would stop and wishing that something interesting would happen. After Natsu and Wendy travels to the other world Edolas with Happy and Charle, the Edolas version of Lucy catches the four of them peeking into the guild.
Upon closer inspection, she then mistakes the Earth Land Natsu for the Edolas Natsu, and proceeds to hug him and then bully him. However, this is short-lived as someone runs into the guild screaming about "Fairy Hunters". Lucy is then seen taking control of the situation, telling Levi to hurry up with the transport field. After they narrowly escape the Hunters, Lucy then proceeds to argue with Levi about how she could have gotten them all killed.
As Natsu and his team hide out, a soldier yells "It's Fairy Tail!" and they tense up for the Army to storm in, but nothing happens. When they peek outside, they see Earth Land Lucy struggling against the guards. Before Natsu could try to help her, she summons Scorpio and blasts all of the soldiers way. When they reunite, Lucy is overjoyed at seeing them again, but shocked when she sees her Edolas version. She tells Natsu to take care of the rest of the soldiers, but Natsu tells her that she's the only one who can use Magic, leading her to believe that she has become the strongest Fairy Tail mage. She then summons Aries and they all escape to the forest.
Lucy explains how she wound up in Edolas. She was saved by Horologium who felt that the space was twisted and hid her in another space for a while. When she was alone in the middle of no where, Mystogan came and explained everything to her and sent her to Edolas. The Edolas Lucy comments on how they're still going to fight against the kingdom even though they can't control their Magic properly (Earth Land Lucy protests that she can use hers). Lucy proclaims, as Fairy Tail's (current) strongest mage that she'll be the one to solve everything, to which Natsu, Charle, and Happy say they have no choice and Wendy cheering her on.
Lucy and ...Lucy?!
Added by Ishthak
Arriving at the town of Sikka, the team decides to stay for the night. Just as Edolas Lucy about to reveal her body to Natsu while commenting that she and her Earth Land counterpart has the same figure, Lucy immediately covered her counterpart up while retaliating that she does mind that.
Natsu, who then begins to laugh, caused Lucy to ask why, and comment that it must be trying to hide the comment of how Edolas Lucy has a better figure or something, but his response of taking a bath with herself stunned both Lucy's. Her counterpart then asked Lucy to summon the celestial spirit that can cut hair, and watched her counterpart change to a shorter hairstyle. The next day, Lucy was furious with Edolas Lucy leaving a note saying that she's going back to her guild. But that attitude quickly changed when she found a book that narrates the history of Edolas. While reading, she and Natsu noticed that an airship just landed. Listening to Natsu's idea of stealing the airship, Lucy decides to battle the Royal Army with Loke. However, Virgo came out in place of him, which Lucy learned that Loke was on a date and cannot be summoned right now.
Nearly captured by the Royal Army, a man with a vehicle came and saved Lucy and Co. and took them out of the city. As they ride on the vehicle, the man introduced himself as Natsu the Fireball to them. When they witness their guild trapped in Lachryma, she tearfully holds Natsu back despite knowing how painful it is. Later, she and Charle make up a plan to know how they should turn back the guild to normal. Lucy plans on using Gemini to transform into Faust and read his mind. After being captured by Edolas Erza, she is put in a different cell to Wendy and Natsu and will be executed.
Erza Knightwalker tries to kill Lucy

Later, Edolas Erza arrives at Lucy's cell to execute her. Lucy then tries to persuade her that on Earth Land, she is a member of Fairy Tail, and is a good, responsible person to whom everyone can count on. However, Erza does not care, and tells Lucy not to confuse her with her Earth Land counterpart.
Erza then suspends Lucy over a balcony, and tells her that she is fortunate, because she likes to look at the suffering of others, and that is why she is titled Fairy Hunter, as she has killed dozens of members of the Fairy Tail. She then sarcastically tells Lucy that she'll be seeing her, before throwing her off the balcony.
Luckily, Lucy is saved by Charle and Happy at the last moment. Charle tries to exploit Erza lack of information and presents herself as Extalia's princess and a daughter of Queen Shagotte. She then tricks Erza into revealing the location of Natsu and Wendy, then tries to get her releasing Wendy and Natsu, which almost succeeds.
Unfortunately, the rest of the royal guard arrives, and Pantherlily informs Erza that Charle and Happy are the "fallen" (traitors). All three attempts to escape. Charle asks Lucy, if she's angry at them. Lucy is very surprised by this question and she really doesn't know for what she should be angry for. Charle held that, it is they fault that she got caught in the first place. Lucy replied that, they had came to save her, and then she adds that she is more surprised by the fact that Charle is a princess.
They then try to reach the west tower, where Wendy and Natsu are both trapped. Unfortunately, Extalia troops face them in the air, and Magic Militia is already waiting there for them on the ground, leaving them trapped. However, in a lucky twist of fate, Faust decides that now is a perfect time to invoke code ETD, which transforms the Extalia troops into a giant cat lachryma.
As the Magic Militia is distracted, the cats and Lucy make their way to the basement of the West Tower, where they are ambushed by Edolas Erza and soldiers once again. Just as Edolas Erza is about to execute Happy, the soldiers behind her are suddenly blown away, and Lucy starts crying tears of joy, as both Earthland Erza and Gray appear, having joined the fray.
She later learns that the reason Gray and Erza escaped was due to Gajeel's dragon slayer Magic. She also learns that the reason she could use her Magic in Edolas was because Mystogan fed her X-Balls, a medicine that allows the earthland mages to use Magic in Edolas. Later, she runs around in the castle with Gray and Natsu trying to locate the king. During that time, Lucy comments on how confusing the layout of the castle is, and that she wouldn't be surprised if there was even an amusement park in the castle. True to her prediction, the group actually encounters an amusement park, along with Hughes and Sugarboy. Lucy then prepares to battle the 2 captains along with Gray and Natsu.
Hughes then show off his weapon, "Command Tact" to attack Natsu with a roller coaster from behind. Lucy shouts at him before falling into Sugar Boy's trap, which makes both Gray and her sink into the ground. After being thrown into the air by Gray, she attempts to free Natsu from the hell roller coaster but fails, as Hughes eventually makes them fall into a body of water. She then sweat-drops as Hughes laughs at a candid shot of them on the coaster.
The presence of water makes Lucy realize that she can summon Aquarius, and she does so. However, the situation turns grim, as Aquarius cannot control the water because Hughes is controlling it. Lucy looks on in shock before being engulfed with the water attack by Hughes. His attack flushes Lucy into a clothes-changing device. Natsu then hatches a plan for Lucy to seduce Hughes with sexy clothing, but fails when Hughes attacks them using monsters located in the attraction anyway. Later, Lucy runs away from the horde of monsters, only to bump into Coco, who has Byro chasing after her. Byro then asks Coco to hand the key used for controlling the dragon chain to him, but Lucy mistakes it as Byro asking for her keys. She then prepares to battle Byro and defend Coco.
Lucy and Natsu beats Byro and Hughes
Added by Ishthak
She summons Taurus, but he is quickly defeated by Byro's Flame Liquid. She then summons Virgo who lands a hit, causing him to fall into the hole she made. This backfires as Byro consumes his Octopus Liquid, turning him into a giant octopus-human hybrid, and captures Coco. Virgo states that she can't do anything and Lucy is forced to run around. She receives the extending whip Fleuve des Etoiles of the Eridanus Constellation from the Stellar Spirit World in order to conserve her Magic power.
Virgo's concern sets Lucy's spirits and drives her to fight for Coco. Byro keeps hurting Coco, causing Lucy to state that protecting your friends is the most important thing. Using the Fleuve des Etoiles, she manages to tie up Byro's legs and makes him hit the Monster Academy, subsequently being caught in the fire of Natsu's punch into Hughes and thus is defeated.
Before Coco could hand them the key, Sugarboy slides by and takes it, then being chased by Gray on a motorcycle. Lucy and Natsu chase after them. Sugarboy softens the floor making Lucy get stuck under Byro's tentacles with Coco. After the cannon is fired, Lucy reappears with Coco on her Legion. Erza, Natsu, and Gray hop on and they head for the Lacrima Island. Helping Natsu and the others Lucy was able to buy enough time for Mystogan to send Fairy Tail back to their world. She became really surprised when she found out that Mystogan was the prince of Edolas.
While helping the Exceeds to escape the Royal Army, she, along with Erza Scarlet, Gray, and Coco, were ambushed by Erza Knightwalker and her force. The two Erza's fight each other, and the rest of them fought against the rest of the army. Even with Loke's help, the sheer number of the Royal Army nearly defeated them until the Edolas Fairy Tail Guild even the odd. She was helped by her Edolas counterpart, and watched the rest of the battle. Magic, however, was taken away from Edolas at a crucial time. Although the Royal Army ran away, she saw the whole guild was in a state of panic. Lucy tried to calm them, but only to be yelled by her counterpart for not realizing that a Magic guild cannot exist without Magic.
Lucy was later seen with Gray and the others as the Anima began to suck up the Exceeds and Earth Mages, commenting on the fact that since the Anima was sucking Magical power out of Edolas, it was kicking them out as well. Lucy then says goodbye to the Edolas Fairy Tail, and travels back to Earth Land with the others.
After arriving back with the others, Lucy is relieved to see that Magnolia is in tact, however is surprised when the Exceed show up. After listening to the 6 year plan, and bidding the Exceed farewell, just as everyone is about to head back to Fairy Tail, they are surprised to see a chibi Pantherlily. When Pantherlily reveals that he has caught someone suspicious, Lucy is seen with the others looking shocked at the revelation that Lisanna's Edolas counterpart is also in Earth Land. She is later seen wondering what's going on when Lisanna admits that she is the Earthland counterpart, and then along with the others, she helps Lisanna return to her siblings
