Castle Doom stood silent, deceiving onlookers from what was happening within its walls. Doom was locked in his lab, formulating a plan for his next attack on Richards and his team, as well as the strange creatures that made the mistake of interfering. He had been investigating the four turtle men since he discovered them on his security footage. So far his search had yielded no results. Finally a name came up that seemed to be connected to the green men: The Shredder. Doom rubbed his chin thoughtfully, "This Shredder character just might be able to assist me in taking out my enemies." He continued his search, this time for information about the Shredder.

Oroku Saki, otherwise known as the Shredder, sat in his office. He was going through some paper work when the intruder alert sounded throughout the building. He burst out of his office, after quickly getting into his Shredder armour, and rushed towards his Dojo, where the alert had originated. Along the way, he was joined by his daughter, Karai, his street goon, Hun, and several Foot ninjas. Shredder threw open the doors and stormed in. Standing in the middle of his Dojo was a man dressed in armour and green fabric. A metal mask hid his face. Shredder looked around the room and noticed the unwanted visitor had brought a small army of robots.
"You dare come into my home and attempt to intimidate me with toys!?" The Shredder bellowed. He flicked his hand, giving an order. Without hesitation, Karai thrust forward, and sliced one of the robots in half effortlessly. At the same time, Hun charged at another robot and smashed it to pieces. The intruder didn't flinch.
"They are not here to intimidate you." The stranger spoke, with his Latverian accent evident in his words, "They are merely my precaution. I have come to propose an alliance."
"What reason would I have to ally myself with you after you intruded upon my tower?" Shredder growled.
"I know about the strange turtle creatures, and I know you have some connection to them." The stranger replied, "They made the mistake of interfering with my plan, so I intend to destroy them."
"You've got my attention."
The stranger walked towards the ninja master. "I suggest we work together to exterminate both our enemies; those meddlesome turtles and the Fantastic Four." The stranger continued.
"The Fantastic Four? Taking down New York's beloved superhero family will not be easy. What do I get out of this deal?" Shredder asked.
"Aside from ridding yourself of those pesky turtles, you'll also obtain free reign over this putrid city."
"You are not interested in taking New York?" Karai asked the stranger, with disbelief hinting in her voice.
"I am already King of Latveria." He told her, "My only interest here is to destroy my enemies."
"No one would remain to interfere with my business." Shredder thought out loud. He stepped forward, towards the stranger. "That is quite the offer. What do they call you?"
"Doom." The stranger replied, "I am Doctor Doom."
"I accept your alliance, Doctor." Shredder offered his hand and Doom shook it.
"Then let us begin." Doom spoke.

School let out and Kaitlyn began making her way home. J.J. caught up with her just as she was exiting the doors.
"Hey, need any back up?" He asked.
"Uh, maybe." Kaitlyn replied, "I still haven't decided if I'm going to tell him yet. I'm still worried about what he'll say."
"I know how that feels. I mean, it's not the exact same kind of situation as yours, but I have to tell my parents I failed that science test last week." He told her.
"You failed?" Kaitlyn asked, with a slight giggle.
"You know I'm not so good with the rock units."
She nodded, still smiling and remembering how J.J. would fall asleep during class discussions about rocks. She looked over to an alley entrance and saw a shuriken with a red ribbon tied to the end. She looked up to find Raph poking his head slightly over the edge of the building's roof. Kaitlyn reached into her pocket and took her phone half way out, wiggling it a bit. Raph nodded, knowing it meant she would call or text him later, and vanished.
"What are you looking at?" J.J. asked her.
"Uh! The clouds." Kaitlyn replied.
"What clouds?" J.J. looked up at the clear blue sky, with not a cloud in sight.
"That's what I mean. I was looking for the clouds, but there aren't any out right now."
J.J. looked at her, knowing she was acting a little suspicious, "More secrets?"
"This one's not mine to tell."
"Fair enough."
The duo walked to the Baxter Building, talking about homework and what the other has been doing lately along the way. They greeted the doorman as they entered the elevator and rode to the top.
"Here we go." She muttered as they entered the penthouse, "Uncle Ben? Can I talk to you?"
"Welcome home, Miss Grimm!" Came H.E.R.B.I.E.'s peppy greeting.
"Hey, Herb. Where's Uncle Ben?" Kaitlyn asked.
"The Fantastic Four are on a mission. Doctor Doom is out and causing trouble in Washington." H.E.R.B.I.E. told her. "Alright." Kaitlyn said, turning back to J.J., "Guess I have to wait 'til he gets back. Mind hangin' out 'til then?"
"Not at all." J.J. replied, walking towards the TV and games.
