The instant Lee made eye contact, Gaara was ready. His hands slapped together in a shinobi hand signal and he uttered "Sabaku...SHURIKEN." The sand that had spilled from the gourd lifted upwards making a sandy wall. Gaara lowered his head, and he smiled sadistically.
The sand seemed to lurch forward, then blasted shurikens made from sand directly at the shadow ninja. The shadow ninja was unaware that these two shinobi were allies, and was thus unprepared for the attack. The sand shuriken collided with the nin, knocking all of the wind right out of his lungs. He was blasted backwards, and out of his peripheral vision, could see that he was going to collide with a tree. He braced himself for the collision, but felt a different kind of pain. The removed ankle weights had made the nin from Konoha 100 times faster. He moved with such speed, it could be considered teleportation and zapped right behind him. Lee spun three times, and kicked the sand ninja straight into the air.
Lee landed swiftly on his feet and smiled at his ally. He gave a dorky thumbs-up 👆 , muttered something about the "nice-guy pose" and zapped back to the shadowy nin, who was still in mid air, and began playing a form of human ping-pong.
The shadowey ninja was at this point, nearly unconcsious, and seemed to float high above the trees from the constant ass-kicking the konohan was giving him. This was when Rock Lee jumped into the air once again, and gave the final ping pong kick downwards. "Konoha Whirlwind Ping-Pong Kick!" Lee made up off the top of his head, and spin kicked the enemy downward. The defeated opponent was looking forward to hitting the ground, and getting away from Lee, but didn't notice that the sand Ninja had his own plan.
Whilst Lee was playing human ping pong, Gaara had made a giant Fist made of sand. It spun wildly in a circle, and when the shadow ninja came into view, hit a home-run. The sand cracked and smashed and hit the crumpled ninja, and shot him back up into the air, where once again, Lee was waiting.
When the enemy got back into the air, Rock Lee was unwrapping the tape around his forearms.
