After a few weeks of defeating Axeknightmon and saved the five legendary warriors, but Davis couldn't forget what the threat Fanglongmon was trying to tell him.

"Hey Davis, wake up." T.K. said waving his hand in front of him.

"T.K.?" Davis said as both of them and the others were hanging at the soccer field.

"What's with you?" Zane said.

"I can't stop thinking about what Fanglongmon said, about this threat." Davis said.

"I wouldn't worry about it. It's been weeks since then and nothing's happened." Zane said.

"Don't take it lightly." Kari said. "It's only a matter of time before this threat shows its face."

"Stop worrying, maybe Fanglongmon was just trying to scare us." Zane said. "Look so far the biggest threat was Axeknightmon. We won he lost."

"True, but the future isn't written in stone." They looked to see Tai heading their way.

"Tai you're home from college." Kari said.

"Only for a little while. I got a call; remember where you guys met Lobomon?" Tai said.

"Yeah that military base." Davis said.

"Well apparently they need some help." Tai said.

…

The Military Base

They took the Space Jumper III to the military base all the way at the end of Japan, but when they did it looked like part of it was caught in the center of an explosion with some plumber ships around. When they landed they met cardinal Rex.

"Well it's nice to see you kids again." Rex said.

"Cardinal Rex what happened here?" Davis said.

"I'm not sure. Something short circuit the wires in our system and caused the self-destruct sequence." Rex said.

"You think another digimon did this?" T.K. said.

"Who knows maybe, or one of those aliens we've faced before?" Kari said. Zane kept walking until he felt his foot step on something and saw that the ground was made of metal. He brushed off the dirt to see it looked like some kind of door.

"Hey guys look at this." Zane said and saw the door.

"Cardinal Rex what is that?" Tai said.

"It's classified." Rex said.

"Well then I'll take a look." Davis said as he used the ultimatrix.

"Icedevimon!"

Icedevimon became transparent and went through the ground to see what was hiding through the door.

"What's with the name shouting, its overkill?" Zane said.

"That kid can be nosy." Rex said.

"That can come in handy in times like right now." Tai said not liking where this might be going until Icedevimon came up and changed back.

"Guys there are aliens and looked like some digimon down there. It's a prison." Davis said.

"Are you serious?" T.K. said. Kari's eyes began to glow.

"I can feel life forms, and digital life forms under us." Kari said.

"Tai, the way they look down there, it's inhuman." Davis said.

"That's because they're not human." Rex said.

"How long have they been down there?" Tai said.

"A computer down there said for almost between four and eight years." Davis said.

"Like when digital gates opened all over the world four years ago." T.K. said.

"Or when digimon were appearing while we fought the dark masters eight years ago." Kari said.

"Cardinal Rex I demand you release all those digimon and those aliens." Tai said.

"I can't do that. They came to our world, a world they don't belong." Rex said.

"Not all aliens are evil and humans and digimon have been living in peace." Tai said.

"Maybe, but I can't take that chance. They could be a threat to our world. Besides it's a great chance to study them so we know how to fight them." Rex said.

"Then the ones that came here to do wrong deserve a fair trial." Tai said.

"You're going to release them all 762 of them." Davis said.

"Wait! That's not right." Rex said.

"Not only is it right, its justice." Tai said.

"No I mean your count isn't right. There's 763 of them." Rex said.

"But the computer said there were 762." Davis said.

"Then that means one's missing." Rex said and a plumber ship started to power up with no one on board. Davis used the ultimatrix.

"Beelzemon!"

Beelzemon hopped on the ship before it could fly to far off the ground and used his nails to stick on the ship.

"Who's flying this thing?" Beelzemon said. He tried to climb up the front to try and get a look, but someone turned the ship upside down. "Hey what's going on?" Then a blaster came out and blasted Beelzemon right off. "Hey no fair!" He hit the ground and was turned back.

"That is never fun." Davis said as the others came by.

"Are you okay?" Kari said.

"I'll live, but we have to track whoever is on the ship down." Davis said.

"No worries our badges can track it." T.K. said.

…

A Small Town

They tracked the stolen ship to a small town and when they arrived it looked like something caused a lot of damage.

"What happened here?" Davis said.

"This is where the ship landed." Zane said.

"Look." Kari said as they saw a police officer down. They ran over and helped him up. "Are you okay?"

"Yes thank you." The officer said.

"Can you tell us what happened?" T.K. said.

"I don't know, it was some sort of creature that could vanish." The officer said. "When I told it I had a family it spared me. Please don't tell."

"We won't." Kari said.

"Looks like whatever it was went this way." Davis said as they followed a trail of damage and made it inside a warehouse. "Whatever we're looking for is in here." They looked around to find the prisoner. Zane thought he saw something and focused on one spot.

"There." Zane said he absorbed stone and tossed a crate. The prisoner revealed to be a Chamelemon. Davis used the ultimatrix.

"Tyrannomon!"

Tyrannomon tried to stomp on it, but Chamelemon started to climb the walls. Zane turned his hands into hammers and tried to pound the walls, but Chamelemon became invisible.

"Hey where'd he go?" Zane said. Then he felt something pound him in the back and Chamelemon revealed himself.

"Hey lizard boy over here." T.K. said. Chamelemon shot his tongue, but T.K. didn't evenmove as it passed him and was stuck on the floor. Chamelemon reeled himself end and got his tongue unstuck. Then Kari brought up a force field around him and the others turned back.

"Nice work." Davis said. "Okay who are you?"

"My name is Chamelemon."

"You're a digimon." T.K. said.

"What are you doing here?" Zane said.

"I was brought to the real world four years ago during a time that the digital world was falling in chaos by a monster named Malomyotismon." Chamelemon said. "I survived, but my friends weren't lucky. When I tried to seek help that cardinal Rex captured me."

"You poor thing." Kari said.

"Yes, my friends are probably gone now because my home was destroyed." Chamelemon said.

"We saw how many digimon were held captive." Davis said.

"Don't worry you can give cardinal Rex a piece of your mind and head home." Zane said.

"You can seek justice." Davis said.

"Justice?" Chamelemon said. "Yes justice and I know how. I will find cardinal Rex's family and take them from him. I would have saved my friends if it wasn't for him so as my friends have suffered so shall his family." Then he disappeared.

"How did he do that?" Kari said as she put down the force field.

"Don't Kari it's a trick." Davis said. Chamelemon shot a heat blast from his eyes and hit gas tanks causing the place to explode, but Kari put another force field around them.

"Really piece of mind, seek justice." T.K. said as he blamed Zane and Davis for giving him the idea.

"Not what I had in mind." Davis said.

"We got more important problems. Chamelemon isn't running anymore, he's hunting." Kari said. They got back to the Space Jumper and head back to the base.

…..

The Military Base

They landed the ship and had to find cardinal Rex before Chamelemon did.

"So now what?" Zane said.

"We got to warn the cardinal about Chamelemon." Davis said. Then T.K. noticed something strange on the ship's shadow, but saw nothing on it.

"Guys since his name is a hint wouldn't the prisoner have chameleon powers?" T.K. said.

"That would explain how he escaped my force field." Kari said.

"Then we got a problem." T.K. said as he jumped up and stuck his legs out, but Chamelemon jumped out of the way, ran off, and vanished.

"Great we led him here." Zane said.

"I think I know a way we can find him." Davis said as he used the ultimatrix and became and old form.

"Garurumon!"

"A dog and again the name thing is overkilled." Zane said. Garurumon started sniffing the ground.

"This way." Garurumon said as he led the way. Chamelemon found cardinal Rex and followed him to his house where his wife was taking care of his 1 year old child. Chamelemon saw them through the window and ready to attack, but Garurumon tackled him down.

"Let me go, I want justice." Chamelemon said.

"This isn't justice, its revenge." Garurumon said. Chamelemon whipped his tongue right under Garurumon's face.

"Visbiblio."

Chamelemon was surrounded by mystical energy and found it strange.

"I made you visible, you can't become invisible." Kari said. Then Zane, covered in stone pounded him and T.K. gave him a kick.

"Howling Blaster."

Garurumon launched his flames, but Chamelemon jumped over it and wrapped his tongue around Garurumon's neck.

"Wide Eyes."

Chamelemon launched flames from his eyes and pushing Garurumon back until he dropped. The others tried to fight, but he was too nimble. Garurumon got up and hit the ultimatrix.

"Garurumon digivolve to…Weregarurumon"

Chamelemon launched his tongue again, but Weregarurumon grabbed it. He pulled him in and kicked him into Rex's jeep.

"Wolf Claw."

He launched his slash blast while Chamelemon was getting back up, but shot him down. Weregarurumon grabbed Chamelemon by the neck and his claw ready to finish him with the cardinal and his family coming out.

"Do it. Do it and so I can join my friends." Chamelemon said, but Weregarurumon let him go and changed back as Chamelemon quivered.

"Some threat." Davis said knowing he wasn't. The plumbers arrived and arrested Chamelemon and Davis scanned his data. "Let me try something." He transformed into his new form.

"Overkill! What do you think? Something different from a digimon name." The others just walked away and Tai talked to the cardinal.

"I hope you learned that not all digimon and aliens are evil." Tai said.

"This didn't prove a thing." Rex said.

"Maybe, but I'm glad that those other prisoners are free." Tai said.

"You didn't." Rex said.

"I did." Tai said. He freed the prisoners. "Again I hoped you learned that not all of them are evil. Maybe next time you should think twice because my friends and I aren't going to be around to save you or your family." After that Tai just walked away regardless of it was the cardinal he just talked to.
