A/N: So we know that the ninja from Konoha are a bit - if not completely - crazy and have some of the weirdest jutsu. What we don't know is how these crazy techniques came to be. So this is going to be my take on how they came to be.

Also I'm open to any suggestions you might have.

FRILL-NECKED-LIZARD

They were surrounded. Kakashi and Rin stood with their backs pressed against each other. Their breaths were labored and their legs shook. Four Iwa-nin stood around them waiting for them to drop their guard. A second was all the time they needed to get in that one fatal shot, putting an end to the Leaf-nin's lives.

Their eyes scanned the area taking in the four Iwa-nin, but at the same time searing for their third teammate. Obito was their only hope in getting out of their sticky situation. Rin was down to her last kunai which she held defensively in front of her person, and Kakashi was left with no other choice than to rely on his father's tanto.

The trio had been separated from their sensei as the man took on a random Jonin from Kiri. Minato instructed them to continue their mission and stated he would join them momentarily. What none of them had counted on was that they would run into a team from Iwa.

All four Iwa-nin were long distance fighters, leaving the trio to dodge any weapon that could be thrown along with the occasional Ninjutsu.

The battle seemed to drag on, and their chakra was beginning to diminish like their weapons supple. Obito was the only one who had any weapons left as he had opted to repeatedly fire Katon Jutsu at the enemy.

Sometime during the confusion of the battle, one of the Iwa-nin managed to get behind the dark haired boy and sent him flying into the trees that surrounded the clearing.

"Oi, you bastards," a familiar voice called out to the Iwa-nin, causing everyone's attention to shift towards the direction of the voice.

Kakashi internally groaned.

Standing on a tree branch was none other than Uchiha Obito. His face had been scratched when he was sent sailing through the tree tops, and his orange goggles were pulled down over his eyes. The dark eyed boy took a threatening step forward. It would have been threatening if he hadn't have lost his balance and ended up standing underneath the tree back using what little chakra he had left to keep himself from kissing the dirt.

Kakashi's right eye gave a slight unnoticeable twitch.

Obito lifted his arms in preparation to form the hand seals to his clan's most revered Jutsu. In the process of lifting his arms his weapons pouch opened and kunai and shuriken clattered around the base of the tree.

Kakashi's eye was twitching more noticeable, as the Iwa-nin questioned the Genin's competence.

Not one to be discouraged the Uchiha quickly formed the hand seals for the Grand Fireball Jutsu. He paused when he didn't feel that sensation of warm chakra building up in his lungs when he took a deep breath. Panicking on the inside, but surprisingly not showing it on the outside, he formed some random hand seals.

Rin and Kakashi watched their teammate intensely. He was about to perform some new jutsu they didn't know about judging by the new series of hand signs he was forming.

"Hidden Jutsu!" He chanced glance at his white haired teammate from the corner of his eye. He felt his jacket fall around him, before he shouted, "Frill-Necked Lizard!"

There was only one way they were going to be able to defeat the enemy and that was to… piss off Kakashi.

Kakashi's eye was twitching violently. When Obito fell off the tree from chakra exhaustion causing the Iwa-nin to laugh, his control snapped. He became a white blur as he sped around taking down the distracted ninja with energy he didn't know he had. Once the last Iwa-nin dropped he set his sights on his idiot of a teammate only to be stopped by a hand placed on his shoulder. Turning his head he was greeted by the sight of his smiling sensei.

Obito curled up in the bush he landed in. He swore to himself that he would only ever use that Jutsu in dire situations or not at all if he could help it.

Frill-Necked-Lizard was a truly dangerous technique when used properly, namely around Kakashi when performed by Obito.
