Eterna Museum

Today the gang made it to Eterna City, but right now they were visiting the Eterna Historical Museum. It was a history museum with artifacts and displays from the past.
Suddenly a security alarm went off; that meant there were burglars in the museum stealing something. The gang ran over to find out what was going on and they came to a chamber of the museum where a glass container had been smashed. There standing on a balcony above the gang were three men with masks on with a Sunflora, Magmar and Poliwrath. When Ash saw the Pokemon he could see thanks to his psychic power that they were actually disguised Ditto. One of the men held a big light blue orb in his hands. 
"We've got the Adamant Orb brothers, let's go." He said.
Suddenly Officer Jenny arrived to try and arrest the men. She has a purple and cream colored skunk Pokemon with her.
Ash looked at the Pokemon on his Pokedex.
"Stunky, the Skunk Pokemon. It protects itself by spraying a noxious fluid from it's rear. The stench lingers for 24 hours."
"Magmar, Smokescreen." One of the men ordered. The smoke was thick.
"Shut the security doors." Officer Jenny ordered. 
When the smoke cleared the burglars and their Pokemon were gone, along with the orb. The police began questioned people right away and the gang was asked questions too. Suddenly Gardenia appeared; she had heard about what had happened at the museum and came to help out. 
Just then Officer Jenny showed up, claiming she had caught a suspect. To the gang's surprise, she had Nando with her.
"Nando, what are you doing here?" Ash asked. 
"I had come to visit the museum, but the alarm went off and then my Sunflora and I were surrounded by the police before Sunflora ran away due to fright." Nando explained. 
Officer Jenny was suspecting that he was one of the men who stole the Adamant Orb. 
"Hold on Officer Jenny." Ash intervened. "Nando isn't a thief." 
"Ash is right; he's not one of the men who stole that orb." Tomo said. 
"Then explain this." Officer Jenny replied.
She held a picture of a Sunflora holding the orb, taken from a security camera.
"That's actually a Ditto." Ash said out loud. "So were the Magmar and Poliwrath."
Everyone else gasped. 
"Are you sure Ash?" Dawn asked.
"I am." Ash nodded. "Nando didn't do this." 
"I agree." A voice said.
This voice came from another Officer Jenny. The one from Viridian City in Kanto. She was in the Sinnoh Region because it was her day off. 
"You should trust Ash's words." She told the Eterna Officer Jenny. "Ash has helped all Officer Jennies in the Kanto Region, Johto Region and Hoenn Region as well as the Orange Islands with solving mysteries and catching criminals. So you should listen to Ash."
The Eterna Officer Jenny wasn't exactly convinced. 
"Take him away and question him." Nando was led away by her men.
Meanwhile the police were patrolling the museum and everyone who was there was not allowed to leave the museum yet. The real thieves noticed the police.
"What shall we do now bro?" One of the men asked.
The eldest of the brothers was the one holding the orb.
"First off Ditto transform into Poochyena, Growlithe and Houndour." He said. "We don't want them to know that you are Ditto." 
The three Ditto did as they were told. 
"Now we take off our masks, dress up normally and I'll hide the orb in my bag." So the three brothers took off their masks, dressed themselves to look like normal people instead of robbers, and got ready to try to leave the museum unnoticed. 
"The Adamant Orb is related to Dialga." The Viridian Officer Jenny explained. 
The Adamant Orb was used to power up it's moves. 
"Oh you mean Dialga, the legendary Pokemon of time?" Ash asked.
"Oh yeah." Dawn said. "We saw the statues of Dialga and Palkia, the legendary Pokemon of time and space outside the museum." 
"Legend says the Sinnoh Region was created by Dialga and Palkia and there are lots of shrines dedicated to them in Sinnoh. And the Adamant Orb was said to have been dug up from one of those shrines." Gardenia explained. 
"What about a shrine for Giratina?" Ash asked. "I've also heard a legend that Giratina created Sinnoh along with Dialga and Palkia."
"That's true Ash, but unfortunately that Pokemon was banished from this world because it was said to have been very violent." Gardenia said. "So there isn't really any shrine dedicated to Giratina." 
"Oh." Ash said.
This made him wonder if it was true.
But now this was no time to be thinking about legendary Pokemon.
"Come on everyone, we need to find the real thieves and prove Nando's innocence." Everyone else agreed with Ash.
He sent out Pikachu, Mothim, Budew, Shinx, Piplup and Gardevoir to help out. Tomo sent out Growlithe, Pidgeotto, Chimchar, Bidoof, Snubbull and Octiliery to help. Dawn sent out her Piplup, Pachirisu, Drifloon, Buneary, Buizel and Smoochum to help out. 
"Everyone split up to search for Nando's Sunflora and the thieves." Viridian Jenny said.
Everyone went their separate ways.
Meanwhile...
Sunflora was still hiding in the museum. When the police got close to it Sunflora became frightened and trapped them with Leech Seed. Right now Ash and Dawn were alone together and he was concentrating his aura to find Sunflora and the thieves. 
"I've found them Dawn." Ash said. "And Nando's Sunflora isn't far away from them."
"We must hurry Ash, I'll get the others." Dawn said before running off.
Meanwhile...
The thieves were still walking around the museum normally, hoping no one would suspect them. The eldest brother had the Adamant Orb in his bag. Also Nando's Sunflora was still walking around, hoping to find him. Suddenly the gang along with their Pokemon, Gardenia and Viridian Jenny appeared. Ash saw through their disguises.
"Gardevoir, bring that man's bag to me." He said.
Gardevoir used Confusion to bring the bag to Ash and he opened it to find the Adamant Orb.
"You thieves can't fool me. I know your Growlithe, Houndour and Poochyena are actually disguised Ditto." Ash said.
After hearing this, the Ditto reverted to their natural forms.
"Now you're going to get it kid." The eldest brother said. He wanted the orb back.
Ash's Piplup, Shinx and Budew stepped forward to fight. The three Ditto turned into a Piplup, Shinx and Budew to fight back.
"Those Ditto can't beat the real deal." Ash said.
"Piplup, Peck. Shinx, Ice Fang. Budew, Extrasensory." He ordered.
It wasn't long before the six Pokemon started fighting.
"You should give up kid." The middle brother said.
"Yeah, your Pokemon will lose to our Ditto." The youngest added.
"Keep dreaming." Ash scoffed. 
Piplup, Budew and Shinx agreed.
Suddenly Piplup, Budew and Shinx started to glow and Piplup evolved into Prinplup, Budew evolved into Roselia and Shinx evolved into a bigger version of itself.
Ash looked it up on the Pokedex.
"Luxio, the Spark Pokemon and the evolved form of Shinx. It's claws loose electricity with enough amperage to cause fainting. They live in small groups."
"Okay then. Prinplup Steel Wing, Luxio Spark and Roselia Leaf Storm." Ash said.
Before the thieves Pokemon could do anything Prinplup, Luxio and Roselia defeated the Ditto and then Pikachu used Thunder Wave to make sure they couldn't escape.
"Caught you!" Ash yelled.
He and his Pokemon were happy with their victory.
Before long the police arrested the thieves and their Ditto and they were led away. 
"Someone hired us to steal the Adamant Orb from the museum. We were going to get paid afterwards." One of the thieves admitted.
So the case was still open, even though the Orb had been recovered. Nando was happy to be free and back with his Sunflora.
"Thanks for that." He told them. 
The gang was happy to have assisted Nando.
"Sorry about that." Eterna Jenny apologized for the misunderstanding.
"Thanks for your help." She turned to Viridian Jenny, Gardenia and the gang.
"Think nothing of it." Viridian Jenny replied. "I'm always doing my job even on a day off."
Ash was suspicious about today's events and turned to Eterna Jenny.
"Officer Jenny." He said. "Is there a criminal organization active in the Sinnoh Region?"
"Yes." She nodded. 
"It's called Team Galactic." She continued. "I bet they're the ones who hired the thieves to steal the Adamant Orb." 
Eterna Jenny believed the same thing.
Even though the Adamant Orb was safe and Nando was proven innocent, the gang had to worry about a new evil organization and wondered when they would encounter Team Galactic.
