Juvia carefully hid in the shadows inside Fairy Tail's guild hall. She had just purchased a "love potion" from some shady dealer on the other side of town.

"With this, Gray will HAVE to pay attention to Juvia!" She uncorked it, little puffs of smoke shaped like hearts drifted up from within. Just as she prepared to blow a few drops toward the seated Gray, Natsu of all people, loudly greeted her from behind, "Hey Juvia!" patting her on the back a little TOO hard. Which caused her to fall forward and sent the potion flying through the air, smacking Lucy in the face and drenching her as she fell backward, the potion bottle having fell between her breasts and soaking her to the bone.

Natsu rushed to her aid, "Lucy! Are you okay!?" he knelt over her, too concerned about her bleeding forehead to notice that she was glaring at him like he was some kind of disgusting insect that needed stomping. (HINT HINT XD)

A loud crack got everyone elses' attention who hadn't been looking at Lucy before, she had just backhanded Natsu, and that wasn't all! Now she had him by the scarf and was literally lifting him off the floor by it.

"GAH! L-Lucy!" Natsu choked. The others merely stood there in shock and fear, even Erza had never been THIS bad!
“Uhhh…Lucy?” Macao tentatively tried to get Lucy’s attention.
“What do YOU want male?” Lucy snarled, then she noticed that she was looking down at Macao and all the rest of the guild hall. Soon her head and the rest of her body crashed through the roof, sending people screaming for cover as wood and other building materials came down.

Makarov just sat there drinking looking up at the evilly grinning Lucy as she ascended higher than any female had ever grown. He gave a peace sign with his two fingers, obviously drunk. “Ha ha! Go get em big ‘un!”

Lucy lifted her booted feet out of the remains of Fairy Tail’s guild hall, listening the the crunches and collapsing of rubble with satisfaction. She peered down into the mess she had made at all the terrified faces looking up at her. “Listen up people! All women are now ordered to come out and join me! All the men are to stay right where you are!”
Erza looked at her drunken guild leader and sighed, “We’d best do as she says, we’re not going to harm a friend and even if we did try, we don’t have a chance! Come with me ladies!”

Cana, Mirajane, and Erza all stood before Lucy’s gigantic boots. Before they knew what was happening, they each had been spat on by the blond haired girl. “Ugh! What is the meaning of this Lucy!?”
Lucy just grinned as the three women began to shoot up until they were her exact height. “Are you ready for some fun girls?”

The women all gave their own enthusiastic, “YEAH!”
