Operation Zero: How on Earth?

Chapter 1

Numbuh One rushed to get a Birthday Suit on Numbuh Fives's head. He had already placed them on the others and activated the odd looking hats, although there were still parts of their bodies that remained in the grip of Grandfather's powers. They were already starting to stir. So was she. Too soon, it was too soon. He might not get it on in…

Just as the boy got the Birthday Suit situated on her head, the Senior Citizombie punched him. Before he could recover, she lifted him off his feet. He felt a tingle under his arms where she held him. He knew what was happening, she was using her powers, agifying him. But if that was the case then…

"Why isn't it spreading? You should be as old as me by now!" The red capped old lady stated angrily.

While she was temporarily caught off guard, Nunbuh One flipped the switch on the Birthday Suit, which was still in reach. The hat activated and the girl returned to her normal age, with the exception of the left side of her face. "I'll explain later," the bald brit assured her. He had a suspicion that it was the same reason his dad was able to hold off Grandfather at that very moment.

The girl now standing before him smiled and said, "Okay. Numbuh Five can wait until the mission's finished."

He turned to the others and stated, "okay guys, I have a plan, but I need your help and we're going to have to move fast." He had no idea how long his dad and Father would be able to hold out but he didn't imagine it could be very much longer.

"Sure," Numbuh Three said cheerfully, her old lady arms behind her back.

Numbuh Four punched his left fist into his right hand, both of which were still oversized for the rest of his own body, "lets show Father's dad how we deal with adults who mess with us."

"So, what's the plan?" Numbuh Two asked as he stood, towering over everyone else because the bottom half of his body hadn't changed back.

Nigel gestured to the manual controls for the Moon Base and his friends rushed over. He moved to take his position.

"Numbuh One, so nice of you to come," a voice called.

All five children turned to face the stairs. At the top stood roughly twenty Citizombies, at the forefront stood Numbuhs Sixty, Eighty Six and Three Sixty Two, the last being the source of the voice.

"Already causing problems for the adults, I see. We were always able to count on you for that." She glanced at the others, then back at him. "Agify them and destroy those suits," she ordered the citizombies at her command.

"With pleasure,"Numbuh Eighty Six stated as the elderly group started their rush down the steps.

Numbuh One knew they were outnumbered but still felt terrible about abandoning the plan. He cast one last glance at the moon base launch controls before shouting, "Escape pods! Now!" The team made a mad dash for the machines, of which only three of the original four remained. The other one was probably just now returning to earth atmosphere with its "delightful" cargo.

Numbuh One allowed the others to pile in before him but as he jumped for it, he felt a pair of hands grabbed his foot and pull him back. He instinctively grabbed the edges of the shuttle door as the owner of the hands, Numbuh Eighty Six called out, "Oh, no you don't."

Numbuh One glanced at the rest of Sector V. He knew that they'd try to help but that if they didn't leave now, they'd be agified again. All of this and the resulting decision took only an instant to run through his mind. He gave his friends an apologetic smile and let go. As yells of horror and protest came from the cockpit, he kicked Numbuh Eighty Six in the chest with his free leg, something he didn't feel very bad about at all. The surprised Citizomby released him and he jumped for the lever that would launch the escape pod.

He heard his friends yell out in protest for a split second before the cockpit slammed shut and the machine was blast off into space, back toward Earth as he took his stand against the crowd of Citizombified, KND trained soldiers. He even managed to hold his own for several seconds before he was subdued.

When I mention Numbuh One's reference to Father helping Zero, I would like to make it clear that it was not an alteration of what happened in the movie. I just assumed that Numbah One was unaware of what had actually happened at the time. When he left with Sector Z, headed for the KND Moon Base, it seemed like Numbuh Zero and Father would team up In order to distract Grandfather. Although the audience watching the episode is aware that Father gave up and returned to his house, the children on the moon base would have no way to know what had happened at that time.
