It was a peaceful day in Magnolia as everyone was minding their own business, that is, until a scream was heard." GET BACK HERE WITH MY PANTS DAMMIT!"" NEVER!"
A girl with shoulder length blonde hair ran from the ballistic man who was ready to kill her. Not that she could blame him." Alexis! Seriously, give me back my-" Gajeel was cut off by the sound of more squeaky voices yelling, give me back my pants. He looked over his shoulder and saw dozens of chibi Gajeels." Oh fuck..." He soon found himself in the guild being laughed at because if his boxers.
Everyone... Black Steel Gajeel wears UNICORN boxers... With rainbows and everything.
Levy somehow managed to get his pants gave them to Gajeel, who gratefully took them." Thanks Shrimp." He grumbled." It's nothing, what else is a girlfriend good for?" The guild members stopped laughing and yelled,"EEEEHH!?"
At about the same time, the chibi Gajeels overran the place and started acting tough, which they were, and kept punching members in the faaaaacccce.
Sorry it's so short but this idea literally came to me five minutes before I wrote it.
