The next morning, Phineas and Reshiram had everyone who has a Pokemon self arrive at the local park in order to discuss the training.

"Attention all allied humans," Reshiram said. "I am sure many of you have questions about what happened yesterday."

"All I know is that this strange horse-like creature appeared in front of me in a flash of light," Baljeet said.

"I do have a name," Keldeo replied. "And it's Keldeo."

"You have been chosen to take part in an army that will battle Darkrai and Zekrom," Reshiram continued. "What occurred last night was the extraction of your Pokemon selves, so they might act like you from time to time."

"That's crazy," Candace remarked.

"Then why is Cobalion staring at Meloetta?" Ferb asked.

Sure enough, Cobalion was looking at Meloetta, since the Iron Will Pokemon was Candace's Pokemon self and the Melody Pokemon was Jeremy's Pokemon self.

"Cobalion, will you stop staring at Meloetta?" Landorus asked. "Reshiram's talking about stopping Darkrai and Zekrom once and for all."

"'Bout time!" Cobalion commented as he snapped out of his trance. "I can't wait to bust those two for destroying the Royal Chus Castle!"

"I stand corrected," Candace admitted.

"Your training will be in the form of a team-building exercises," Reshiram said. "This is so you will gain trust between human and Pokemon. The stronger the trust, the powerful your teamwork is. Phineas, you do not have to do them with me since I can identify your strong bond with me. As for everyone else, I want each human to wear a blindfold..."

As Reshiram instructed the others about the team-building exercise, Phineas thought about what happened three years ago when he met Jimmy and the others from inside the Earth's inner core.

Flashback

"Why do you want us to play dumb?" Phineas asked Jimmy.

"You helped us defeat Lucius," Jimmy explained. "We might return the favor someday and you need to remember us when that day comes."

End Flashback

"Some promise he made," Phineas bitterly thought. "I needed their help three years ago!"

As the others were working on the team-building exercise, Greg arrived with four others. "Attention everyone," the Serperior said. "I would like you to meet Omega, Atlantic, Ozone, and Erupt. They will help you with defeating Darkrai and Zekrom."

Omega was mainly white, golden, and grey with battle spikes on his arms that appeared to be used as weapons. He also had a sword and a shield. His sword was razor sharp with spikes coming out of the sides of the sword. His shield was shaped like Arceus' rings with a white and gold center and the Jewel of Life in the middle.

Atlantic was a deep blue color, almost cobalt, and her helmet design was like that of Kyogre's face. There were also red markings across her body, and her eyes glowed yellow.

Ozone was emerald green like Rayquaza and there was a tail where her legs would be, but it looked like she was having trouble walking since she used crutches to help stand and walk. She also had dragon-like wings on her back.

Erupt resembled Groudon, complete with his red and black-striped shield and his sword was made out of lava and stone. Smoke was seen coming from his body and lava was seen in small cracks on his joints.

"Our parents were killed three years ago," Omega explained to Phineas and the other allied humans. "And we vow to make Darkrai suffer for three years of torture."

"And how can we be sure you won't betray us?" Phineas coldly asked. "You might ditch us at the last minute when we need your help!"

"It is okay Phineas," Reshiram reassured. "I have crossed paths with them before. They can be trusted."

Phineas glared at the four newcomers. "Fine," he told Omega. "But I still don't trust you and your friends."
