Hey everyone! Okay, I started watching the anime Brave Police and that gave me the idea to create a crossover, I like both of these animes and I had an idea where The Brave Police and their human friends have Guardian Characters to help stop villains and their X-Eggs or Characters. I thought it was cool, so I'm putting it up to you then. Hopefully, this will be good.

"blah" means talking

'blah' means thinking

blah means Character change or Transformation/Combion

blah means villain description

blah means attack or weapon

Episode 1: Introducing the Robot Detective Pt 1

It was morning in the city of Nanamagari, the streets were deemed as the sun rosed through the city. But in one particular house in a particular neighborhood, where our hero's adventure begins.

It all was quite at the Tomonaga house, well, until there was a loud crash downstairs that had awakened two sisters. They both opened their doors at the same time to see what was all the noise.

"What the heck?" The middle sister named Kurumi said as she rubbed her green eyes before she had an angry look on her face. "That just woke me up!"

"Oh, good morning." The elder sister Azuki said to her sister warmly with a smile on her face.

"Whaddaya mean 'good morning'!? It's only 6 am." Kurumi asked her a bit confused.

"Waking up early is good for the health. You should get up early for a change, Kurumi." Azuki replied with a kind gesture.

Kurumi just sighed at that statement. "Darn it, I can't win against you, Azuki." She said in defeat. Then another clang as heard which made Kurumi can't standing anymore. But she already knew who it was making such noise.

'You know you'd wake us all up with all that noise!' She thought before she growled.

"That idiot! Now I'm SO awake!" She yelled as she ran down the stairs to the kitchen. Once she was there she saw that it was indeed her younger brother Yuuta, who was in his music note pajamas and was on the floor with dozens of pots and table were and also some food as well.

"Hey, Yuuta!" She yelled her hands on her hip. Yuuta jumped in surprise before looking back and saw his sister.

"Sorry, did I wake you?" Yuuta asked her rubbing the back of his head.

"Of course you did!" Kurumi yelled again which made him shake a bit as she continued. "What's the fuss this early in the morning!?"

"I-I was going to eat before leaving for school," Yuuta explained before looking down at his cat who was eating happily. "but the cat beat me to it."

"Geez," Kurumi said looking at the cat.

"Oh, dear," Azuki said when she came down and saw the mess with her own eyes.

"Azuki, you should tell him off, too," Kurumi said to her sister.

"Oh, well," She said before she looked down at Yuuta with a kind smile. "Yuuta, I'll clean that up later. Can you get the newspaper, please?"

"OK!" He said happily as he stood before he ran off to the door.

"And don't forget to check that egg of yours okay!" Azuki added as she yelled out.

"I swear, Azuki. You're too soft." Kurumi said giving her sister a pouty face. But all she got as a response is a smile and a wink.

Yuuta grabbed from the mail been before gasping as he saw the sun raise setting in front of him. He yawned as he stretched for a bit before he gave a smile. But then he remembered something.

Oh! I got to go see if Rythm's ready!' He thought before running back inside to his room.

Once he was inside, he ran upstairs and got to his room and opened the door he ran inside and started changing.

"Rhythm! Are you ready?" Yuuta called out as he looked around his room.

"You know I'm always ready to roll bro." Yuuta looked over and saw a dark blue color egg with blue flowers on it flew to him and hatched. And appeared a little figure of a boy with long violet hair that reaches to his waist. He wears a baby blue beanie, long-sleeved shirt, blue vest, and jeans. On his feet are white shoes and blue soles. Around his neck, he has a pair of blue-black headphones.

"So is it time for me to meet your friend of yours Yuuta?" Rhythm asked him.

"Yup! I just don't know if he could see you though..." Yuuta trailed off when he mentioned the 'can't see you' part. Rhythm looked at his owner with a hint of sadness, his owner thought ever since Rhythm hatched that everyone could see him, but they couldn't. But right now, he wanted Yuuta to think positive about it even if this fails. But yet, he highly doubts it would. Because somehow, he had a feeling about this feeling with this friend of Yuuta's.

"Cheer up Yuuta!" Rhythm said to him putting his hands in his pockets. "Besides, even he doesn't see me. He could still be cool in my book!"

"You really think so?" Yuuta asked smiling. Rhythm nodded happily, this made Yuuta very happy.

"Cool!" He said before grabbing his school bag.

"Come on Yuuta! We have to eat breakfast first before we go see him!" Rhythm reminded him.

"Right!" Yuuta said before grabbing his school bag.

Soon, Yuuta and his sisters were sitting at the table eating breakfast. But unknown to the sisters, Rhythm was sitting on Yuuta's left and was eating happily a small piece of bread. "Sis, one more slice, please?" Kurumi asked polity to her sister as she took a sip of her cup.

"Kurumi, you're eating again?" Azuki said to her.

"I woke up too early," Kurumi replied to her. "so now I'm hungry."

"Which reminds me," Azuki looked over at Yuuta as she covers her toast with butter. "Yuuta gets up early these days." Yuuta coughed out haft of his toast that he was eating while Rhythm was cool and kept eating his bread.

"What was that supposed to mean?" Kurumi asked him leaning over before she gasped. "Oh, I know!" Yuuta looked at her nervously as Rhythm just looked at her.

"You've got a crush in class, don't you?" She said before she put on her dreaming face has her eyes sparkled at the thought. "She goes to school early, so you go early to be alone with her. You sure don't act your age!"

Yuuta looked nervously at her, he doesn't even know what to say about that. Rhythm saw that his owner was in distress, so he had to help him out.

"Don't worry Yuuta, Character Changes!" Yuuta then gained a pair of headphones around his neck as he looked at his sister. "You've got it all wrong, sis!" He said with a smile. "I just wanted to check on a friend of mine! So cool you're romance biz!"

This made Kurumi looked at him surprised. "Oh, really. Well, sorry, I just thought it was a crush." She said a bit surprised.

"Well, I was just checking on Deckerd.." After he said that, he gasped out of his Character Change and the headphones disappeared at what he just spilled. Rhythm sweat-dropped at what happened.

'Oh, no.' He thought.

"'Deckerd?'" Azuki repeated.

"what's that?" Kurumi asked. Yuuta thought quickly at this.

"Whoa. Look at the time! I'll be late! Bye!" Yuuta quickly said as he stood up from his seat before he quickly grabbed his school bag and ran out with Rhythm close behind him.

"But it's still only 6:30!" Azuki called out but he was already out the door.

Kurumi giggled. "I want what his friend thinks of him at school."

Yuuta closed the front door behind him and he sighed in relief before looking at Rhythm. "Thanks for the save Rhythm!"

Rhythm smiled. "Anytime Yuuta! Now com'on, let's not wait any longer!"Yuuta nodded with it as well before he ran out.

He ran as fast as through the neighborhood with Rhythm behind him. He ran until he found a clear land where an abandoned building was nearby. Yuuta then crawled over a wired fence with Rhythm on his should as he stood back up once he was on the other side. Yuuta looked at the place with a smile as he looked over at Rhythm who was smiling back at him. before Yuuta began to walk forward. He walked through trees and tall grass before he spotted a metal plate lying on the field. He lifted the plate carefully and set it aside, revealing an air vent. He looks over at Rhythm who was floating beside him.

"Are you ready to meet him, Rhythm?" Yuuta asked.

"You know I am, Yuuta!" Rhythm said to him with a wink. Yuuta smiled as he nodded before looking down in the air vent.

"it's me, Deckerd!" He called out.

Inside the abandoned warehouse, a robot-like police officer's orange optics started to glow brightly.

"Deactivating security system." He commanded, then the computer system next to him started to shut down.

Yuuta smiled brightly as he stood up, Rhythm floated to his bag and went inside. When his head popped out a bit he and Yuuta giggled at each other and put their pointing finger over their mouth as a 'shush' motion before Rhythm went back in the bag. Once Rhythm was safely put, Yuuta leaped into the vent and slid down. He let out an excited yell when he blasted his way through the vent, he landed on a large pair of servos. Yuuta looked up as he gave a thumbs up.

"Nice catch, Deckerd!" He said happily. The robot looked indeed like a police officer and he was in fact very big as he looked down at Yuuta.

"I'm glad you came, Yuuta." The robot said as he put his friend down on the ground gently. Yuuta stood as he smiled at him.

"How are you?" He asked him.

"Good. Looks like you're doing well, too." The robot replied.

"Yeah!" Yuuta said smiling before remembering something he almost forgot. "Oh yeah, I've also invited someone to meet you, Deckerd!"

Deckerd looked at him confused. "Yuuta, I thought you said you would keep this meet up a secret?" He said to him confused.

Yuuta just smiled sheepily at him. "Well, remember that little blue egg I always brought with me when I come to visit?" He asked.

Deckerd nodded which made Yuuta smile wide. "Well, there was actually a guardian character inside!"

This made Deckerd looked at him more confused. "'A Guardian Character?'" He repeated. "What's that?"

Yuuta nodded before looking back at his bag. "You can come out now, Rhythm!" He called out to the bag. Then the top flipped open and came floating out was Rhythm. He looked at Deckerd, he admits that he didn't expect his owner's friend to be a giant robot-like police officer. But he was cool with it.

He floated to Deckerd's face. "Yo I'm Rhythm, nice to meetcha!" He greeted him with a smile.

Deckerd looked at him for a moment, before he realized that Rhythm was talking to him. "Oh, hello," He said.

Yuuta looked shocked at this. "You can see him!?" He asked a bit surprised.

This made Deckerd confused. "What do you mean Yuuta?" He asked him.

Yuuta smiled nervously. "Well, when I tried to show him to my sisters, they didn't believe me. They thought I was imaging him." He explained as he looked over at Rhythm who was floating around Deckerd curiosity.

"And why is that?" Deckerd asked as well. Rhythm looked at Deckerd with a smile.

"Well, you see, I'm invisible to normal people, and only owners of Guardian Characters and pure-hearted children can see me." Rhythm said.

"Really?" Deckerd asked who looked surprised at that.

"Yup," Yuuta said before looking at Deckerd with a big smile on his face. "but at least you can see him Deckerd!" Deckerd smiled at that, then he remembered something.

"Yuuta, I've mastered that trick you taught me," Deckerd said to his human friend. This made Yuuta excited, while Rhythm looked at them confused.

"Show it to us!" Yuuta and Rhythm cheered.

"Here goes!" Deckerd stood on both his feet. Taking out his pistol and badge he stood tall and proud as he held the two up in a pose.

"Hold up!" He exclaimed as he pointed his pistol forward and held his badge close. "Brave Police Deckerd!"

"How's that? Good enough, you two?" He asked him.

"It's perfect!" Yuuta said excitedly. Rhythm smiled at the pose Deckerd's pose that he did.

"That was awesome, Deckerd!" He said giving him a thumbs up. "Now you can proudly declare yourself as a robot detective in public!"

Deckerd smiled at the two at those responses. "I see it was worth practicing." He said as he put his pistol and badge away.

"Hey, maybe next time, I'll come up with another pose for you, okay?" Yuuta said think wonderfully at the thought.

"Next time..." Deckerd muttered looking away from the two. This was when Rhythm felt a sad tug with Deckerd's heart. If you could call it that. He knew something was up about.

"Yo, Deckerd?" Rhythm said a bit confused. "You alright?" Before Deckerd could answer him, his head shot up when he head the sound of the elevator shaft. He looked at the two.

"Someone's coming." He exclaimed.

"It isn't even 8 am yet!" Yuuta said confused. He looked around frantically to find somewhere to hide. Rhythm looked too and saw some boxes lying around and floated over.

"Over here, Yuuta!" Yuuta looked at where Rhythm was and grabbed his bag and ran over. Deckerd rushes over to his original position on his platform. Soon the elevator came down, Rhythm looked to see two men walked out when the elevator doors opened.

"It's so typical of you to drag me here so early in the morning. Guv' Saejima" The man in the brown jacket said as they walked over to Deckerd.

"And you're probably the only one who calls me 'Guv'." The man in the grey suit replied.

"Engineers can get the job done, even with a foul mouth." The man in the jacket said before the two stood in front of Deckerd and analyzed him.

"How do you like it?" He asked looking at him with a hint of proudness. "It's powerful, yet agile, as you requested."

"Of course, it's equipped with the latest A.I technology in its manmade brain." He continued.

"Once we formally induct him, police institutions in Japan and worldwide will be revolutionized." The man in the grey suit said with, please.

"And he can finally emerge from this pit." The other man said before looking over at the grey-suited man beside him. "So, what do you say, Guv'? Shall we go for some coffee?"

"Hmm..." Rhythm then floated over there. He stopped in front of Deckerd as the two men walked back into the elevator. Once they were left for go he looked over at Deckerd as Yuuta sighed in relief as he came out of his hiding spot and walked over. Deckerd then looked down smiling that they weren't caught.

"We'll be going now," Yuuta said tugging the strap on his shoulder. Deckerd nodded at that, Yuuta looked over at Rhythm. "com'on Rhythm you have to get back inside you're egg before we head to the school."

Rhythm nodded. "Okay bro," He said before he looked over at Deckerd with a smile and gave him a little wave. "See ya, Deckerd!" And with that, Rhythm then returned back into his egg and Yuuta caught it before it fell and place it inside his bag. Deckerd kneeled and offered him a hand and Yuuta climbed on. Once he was safely on, Deckerd carried him to the air vent and Yuuta pulled up the lid. He looked back at Deckerd with a smile.

"See you later, Deckerd!" Yuuta said looking up at Deckerd.

"Yuuta.." Deckerd trailed off before continuing. "I have something to tell you. Can you come again after class?"

"Sure. But what's it about?" Yuuta asked him.

"Well..." Deckerd said looking away for a moment but looked back at Yuuta with a smile on his face. "I'll tell you later." Yuuta looked at him a bit confused but nodded anyway.

Later at school in his Fourth Grade classroom, Yuuta was looking out the window next to him as his teacher was talking.

'I wonder what could it be...' I thought as he looked out with his mind in thought.

Somewhere in the city of Detroit, a security bot was shooting up high before it was squashed as a robot stand above it. The robot looked like a cross between a sumo and bootleg toy, but who was controlling it was a man inside of it with a console.

"Smart asses..." He said with a sinister grin on his face. "I know you're out to get me, but don't underestimate My Death Magnet."

The Magnetic energy freak, Dr. Gauss.

A genius who uses magnetic science for his ends,

he has built a trade of selling

weapons built from stolen robots.

Then the robot realist a magnetic soundwave-like beam through its chest, this has made the security bots froze and couldn't move.

"What the heck?!" One of the men that were controlling a security bot. Then suddenly, the two bots collided together that made an explosion.

"Watch out for those magnetic beams!" Said one of the men in a security bot as he was shooting. As they did this, a news helicopter was flying above as the cameraman was filming the scene.

"Dr. Gauss' robot is attacking Detroit and the whole is in a panic." Said the reporter-man as he looked at the scene. Then two air fleets came down and started shooting at the robot. The robot then turned to them.

"Pests!" Dr. Gauss yelled as he shot them with his magnetic beam. When they were hit with it, the two air fleets collided together that made an explosion.

While this was going on it was also on tv through a glass window as people in the streets were watching this all unfold.

"It's magnetic beam has just caused two helicopters to collide. The police are powerless against it." But within the people watching this, Yuuta was there watching it with Rhythm floating beside him.

"That's not good!" Rhythm said as he was watching this. Yuuta on the other was angry at this.

"If Deckerd were there, he'd be arrested pronto..." Yuuta said before he and Rhythm went off.

The two made it back to Deckerd, they all sat on the floor.

"What was it you wanted to say to us, Deckerd?" Yuuta asked as Rhythm sat on Deckerd's shoulder.

"Yeah, Yuuta mentioned about it earlier too." Rhythm said to Deckerd.

"There's something I haven't told you all this time," He said looking down at Yuuta. "six months have passed since we've first met. I knew I had to tell you eventually, now, the time has come." He looks over at Rhythm then to Yuuta.

"Ready Yuuta? Listen closely..." He asked him to be sure. Yuuta nodded at this, Rhythm felt something, and he hoped he was wrong.

"Tomorrow, I will be formally inducted into the police," Deckerd paused for a moment before continuing. "an immense amount of data will be fed into my brain..."

"Deckerd..." Rhythm trailed off before Deckerd kept talking. "Data related to accidents and cases..."

Somewhere, in a conference room, they were all talking about The Brave Police Deckerd.

"As technology advanced, once unimaginable crimes have become commonplace." The man in the grey suit from earlier said to a crowd of reporters.

"To address these new challenges, the police have decided to introduce a new class into its ranks." He said as some of the reporters flashed their cameras. "The Brave Police."

Then behind him was a screen where it showed a diagram of Deckerd. "This detective is the outcome of the Brave Police Project which aims to help eradicate crime."

"Robot detective..." A person from the crowd said.

"The ultimate goal of the Brave Police is to create a peaceful world free of crime." Another image of Deckerd with his pistol was shown on screen.

"What is the name of this robot?" A reporter asked.

"We call him Deckerd." The grey-suited man answered.

"How will it be controlled?"

Another image was brought up where they showed how Deckerd was made. "Equipped with the most advanced A.I. to date, Deckerd fully understands human speech. He can move independently once a command is issued. Thus pilots and remote controls are not necessary."

"So, is Deckerd able to conduct a criminal investigation on his own?" another one asked.

"No, that is not possible. Deckerd is a robot after all."

"You'll be reformatted? You mean you'll forget about me?" Yuuta asked in shock.

"Yes, unfortunately," Deckerd said who was standing up. "Everything I know about you is stored in my memory. But once I am fed new data, yours will be erased."

Yuuta ran up to Deckerd with an upset look on his face. "No way... no!" He said as he started to cry. "Please, Deckerd, stay the way you are!"

"Yeah Deckerd!" Rhythm said as he floated in front of Deckerd. "You shouldn't have them make you forget the times you had with Yuuta! Stay as our friend!"

"I cannot do that," Deckerd said as he looked at the two of them. "I was built to uphold peace and order. I must fulfill my mission."

Yuuta looked at Deckerd with his tears coming out of his eyes. "Yuuta, you know what I'm saying..." Yuuta wiped his tears before he ran up to Deckerd and hugged his leg. "Deckerd!" Deckerd kneed down without moving his leg and hugged Yuuta back.

"Yuuta..." He said looking down at him. Rhythm looked at this scene unfold, he felt the feeling being tugged now. He clutched his chest as tears were in his eyes.

"Oh, Deckerd... Yuuta..." He whispered before he floated over to them and hugged Deckerd's head as his tears dripped on Deckerd's cap-like head.

WEEELLL, I finished it finally! I just hope you all like! Anyway, if you like it, review, and the like, and I'll see you guys later! Bye!
