The turtles were out doing they're nightly patrole when they saw something on the opposite roof,

It was big... Really big! The turtles stopped and watched the giant shadowy blob move quickly and silently through the dark.

"What do you suppose that is?" Leo turned his head in his brothers direction, unable to take his eyes off the giant. "I dunno, but whatever it is, its huge..." Raph folded his arms and chewed on his bottom lip.

"Dudes! We gatta check it out! It could be, like, another mutant! Like us!" Mikey was the first to jump down to street level. He ran across the road and began climbing the fire escape. "Come on dudes! Or are you, chicken?" Mikey teased as he continued to climb.

"I'm not a chicken! Cummon Donnie!" Raph puffed out his chest and slid down to the street. Donnie looked at Leo and shrugged, "It couldn't hurt to see who it is. Right?" Leo closed his eyes and let out a heavy sigh, before following after Donnie.

Leo caught up with his brothers on the other side of the street, Mikey was already half way up the fire escape when the giant figure appeared above them.

All four of the turtle froze where they were, eyes fixed once again, on the giant shadow. A large metallic creaking sound echoed in the empty streets.

Mikey looked up and saw the giant pushing on the fire escape, its ginormous foot bending the metal, as if it were made of paper Mache. "Uh-oh dudes, that's not good!" Mikey leapt of the fire escape just as it came crashing down.

All four turtles were left standing in the middle of the empty street, eyes wide and breath heavy. Raph was helping Mikey up, while Donnie inspected the now broken fire escape. "Leo, what do you think that was?" Donnie turned to Leo, his eyes quivering. "I don't know Donnie, but it doesn't look like its done with us yet."

Leo was stareing up at the roof top, the giant stareing back at him. Leo swallowed his spit but his mouth had gone dry. The giant jumped down from the roof, cracking the cement sidewalk as it landed.

Leo began to sweat as his heart raced in his chest. The giant came closer to the turtles, each step shaking the ground like a mini earthquake.

It was close now, only 3 feet away. Leo could see its chest rising and falling with each steady and calm breath. He could see light reflecting off its deep green eyes, eluminating them.
It was so much bigger up close, its hands were massive, they could crush Leo's head, right here, right now. But they didn't, the giant just stood there, observing them. Its long tail making scraping sounds as it swayed back and forth.

It seemed unsure of what to do now that it was so close to the turtles.
Leo took a deep breath and instead of reaching for his Katana, he held out his hand. "Hi."
