On the walkway of the castle of Zephyr Heights, there we see Drapion laughing sinisterly while holding Sunny, Izzy, Hitch, Zipp ,and Pipp after he has successfully conquered the city as well as killing Greninja, now no one will ever stop him, things seemed bleak for the ponies of Equestria.

"Oh no." Queen Haven said in a weak and worried tone as she witnessed the unconscious body of Greninja while in the throne room.

"Dra! Drapion! (Hahahaha! I've done it! I'm now the ruler and conquerer of this land! Now no one will be able to stop me!)" Drapion laughed in a vile way.

The mane five were trying desperately to get out of Drapion's grip but, his new powers that the potion gave him made it futile as it enhanced his strengths and all. Sunny then looked at Greninja to see him still unconscious and not moving, he was their only hope.

"Greninja! You have to stand up!" Sunny exclaimed, but, the Ninja Pokemon did not respond "Stand up please! You said that you want to protect countless of lives including your friends right? Your duty and dream is not only your desires, but, also, the ponies of Equestria, and ours! Only you can fulfill your duties and protect us! So for everypony, for us, please stand up! Greninja! Greninja!" She shouted while in tears, but, Greninja still did not respond. And Drapion laughed at Sunny's pleading.

"Ah!" Greninja exclaimed as his eyes shot open. He then saw white underneath him. "Huh? Where am I?" He asked in a bewildered tone as he slowly sat up straight. He looked around himself to see that he is in a void space where everything is white.

"What is this place?" He asked as he stood back up, he found something weird too, he was not feeling any pain anywhere in his body. "Am I dead?" He asked himself in a shocked tone.

After scrutinizing the white void space around him for another brief second, something popped into Greninja's mind. He remembered that he was fighting against Drapion in Zephyr Heights along with his friends, by the time they got caught in Drapion's claws, Greninja desperately tried his best to save them but, he wasn't successful due to his injuries and he got hit by it's hyper beam.

"Guys?!" Greninja called them, but, he didn't get a response, instead, his voice echoed "Sunny? Izzy? Hitch? Zipp? Pipp? Where are you guys?! Are you all okay?!" He shouted hoping to get a response but, he still did not get a reply from them.

At first, Greninja thought that he was all alone in this weird and peaceful place but then, a voice spoke.

"Hello Greninja, it's been a while old friend."

Greninja's eyes widened when he heard the familiar voice, that particular voice only belonged to one person he knew.

"Is that?" Greninja thought as he turned around. When he did, his eyes widened when he saw who was in front of him. It was his trainer Ash Ketchum!

"Ash? Ash!" Greninja exclaimed in a happy tone as he ran towards him, and Ash ran towards his Pokemon too.

Once the two got together, they both immediately embraced each other in a hug to express that the both of them are contented to see each other after so long. They haven't been in touch with each other for years!

"I don't understand, how did you?"

"Arceus transported you here after you got killed by that Drapion." Ash replied to him as he broke the hug which got Greninja surprised "After that, I got a message from him saying that I could see you here again and I took it, after all, I've always thought about you Greninja." He told him.

Greninja was beyond surprised to hear this, he is really dead right now. But thankfully, Arceus managed to transport him here so that he and Ash could be reunited after so long. He always wanted to meet his trainer again. However, what got Greninja perplexed is how he could understand him.

"Wait Ash, how can you understand me?" Greninja asked with a perplexed expression.

"Oh, it's all thanks to my Aura powers given to me by Arceus." Ash replied which made Greninja nonplussed "My new powers allows me to communicate with any sorts of Pokemons, and many more." He added.

Greninja was beyond flabbergasted by this, he never knew that Ash was an Aura Guardian.

"Wow, now that is cool."

"Indeed it is Greninja." Ash said with a chuckle "Anyways, my purpose for being here is not only to see you again." He told him.

"Huh? What is it?"

"Ever since the problems in Kalos have been resolved, you can now let that go and rest easily." Ash told him as he brought out a PokeBall that belongs to Greninja, he then, placed it in front of his Pokemon and enlarged it "Greninja! Will you agree to travel with me and take on the challenge of becoming a Pokemon Master once more?" Ash asked him.

"You will also become the world's most strongest Pokemon if you come back with me." He added.

Greninja couldn't believe this, this is what he always wanted, he was always eager for the day to be reunited with his great trainer Ash to arrive and resume his quest on helping him to become the world's Pokemon master, becoming the world's most strongest Pokemon would be an honor. But, he just couldn't accept it, he still remembers that his friends are still in danger in the hands of Drapion in his new form and power, and he could not let the ponies of Equestria get maltreated by him. Letting out a sigh, he looked at Ash with an apologetic expression.

"I'm sorry Ash, but, I can't." Greninja said with an apologetic expression.

"Huh?" Ash said in a perplexed and surprised tone "What do you mean Greninja? Haven't you been eager for this moment? Even Serena's Braixen is eager to see you again after so long." He told him as he lowered his PokeBall.

"I know Ash, I have been eager for this day to be reunited with you, and seeing Braixen again would be nice too." Greninja replied with a nod remembering the wonderful times he and Ash had during their journeys through the Kalos region, as well as how he loved Braixen "But, my friends are in danger by Drapion back in Equestria, and I can't just abandon them, it would hurt my heart. As their friend, I must do everything I can to protect them, I hope you understand." He told him with an apologetic expression.

When Ash heard this, he let out a smile before lowering his PokeBall and clipping it back in his belt compartment. After that, he looked at Greninja with a proud smile.

"I understand Greninja, I'll respect your choice to return." He said putting his hand on his shoulder.

"Thank you Ash." Greninja said giving him another hug "I knew you were the perfect trainer I've chosen. From the time I saw you when I was a mere Froakie. I knew that you were the trainer that I've been waiting for, I trust my judgement." He told him.

"And I always knew you were the greatest Pokemon I could've ever had." Ash said.

After hugging each other for ten more seconds, Greninja and Ash both broke their hug and let out chuckles. Then, Ash stretched his right hand out to him.

"Take my hand Greninja, and I'll return you to Equestria." Ash told him.

Greninja nodded and began to reach out for his hand with his left hand so that he could be transported back to Equestria. When he did, both of them gripped onto each other's hands and Greninja's body began to glow brightly.

"Go get him Greninja, I know you can. The both of us, stronger until the very end!" Ash exclaimed in a proud tone.

Back in the castle walkway in Zephyr Height, Drapion was seen staring at the three ponies in his claws with a sinister smile, he was deciding on what he wants to do with them, he could either eat them, or poison them and let them rot.

"You won't get away with this." Hitch told him "We're gonna make you pay for killing Greninja!" He said shooting Drapion a glare.

"Yeah!" Sunny, Izzy, Hitch, Zipp, and Pipp exclaimed in unison.

Drapion could on chuckle in a vile way from hearing them say that.

"Drapion. (Oh please, as if Greninja is going to come back to life.)"

Then, without a warning, a water shuriken collided in Drapion's face. The contact made the Ogre Scorp Pokemon grunt in pain, releasing the ponies in the process.

"Dra? (Ow, what the?)" Drapion said looking in front of him to see who hit him.

When he did, his eyes widened in astonishment to see who was in front of him, in front of him was Greninja standing up on his feets with his pony friends standing next to him with flabbergasted and shocked expressions, it also seems like all of the injuries sustained on Greninja have evaporated.

"Greninja. (I will not let you achieve your barbaric goal Drapion.)" Greninja told him sternly.

"Greninja! You're okay!" Sunny exclaimed as she and her friends embraced the Ninja Pokemon in a hug.

"See, I told you that I would protect you all."

Drapion couldn't believe what he saw, how was this even possible? Greninja should've been dead from that hyper beam attack that he launched! Then, he got angry and he slammed the floor with his claws in anger.

"DRAPION?! (HOW IS THIS POSSIBLE?!)"

"It's called friendship and bond Drapion." Sunny replied, "Me and my friends always have each other's backs when we encounter trouble. We work together and never leave each other's sides. That is the true definition of friendship." She told him putting her left hoof on her chest where her heart is.

"Indeed, our hearts are as one." Greninja said as he placed his right hand on the heart level of his chest.

Then, Greninja's eyes glowed brightly red and Sunny felt something happening through her body which got her perplexed. A brief second later, both Greninja and Sunny synchronized with each other and a veil of water surrounded the Ninja Pokemon, transforming him in the process. After that, the veil of water broke apart and the water all flowed to Greninja's back, five seconds later, a giant water shuriken was formed on his back. The sight shocked Drapion, and astonished Hitch, Pipp, and Zipp.

"Whoa! Check you out Greninja!"

Greninja now has purple patterns on his head that matches Sunny's hair colour, bright orange patterns on the sides of his head that matches her ear colour, and a giant water shuriken on his back. He has now transformed into Sunny-Greninja after synchronizing with her.

"Wow Greninja, I see what you see." Sunny said in an astonished tone.

"Indeed." Greninja said with a nod "What you're experiencing now is battle bond, which is the ability that I told you about." He informed her.

"That is awesome." Sunny said.

"Indeed, now let's kick Drapion's butt." Greninja said getting into a battle stance along with his friends.

"Dra. (Grr.)" Growled Drapion "Drapion! (This time you guys will die!)" He exclaimed.
