In Hydro's bedroom, of Zephyr Heights castle, the young pegasus colt was seen studying his health science book on pertinent and beneficial herbs and other sorts of treatments that would have the ability to patch up ponies wounds that they sustained on their body tissues. The reason why Hydro has gleaned interests in health science is due to him wanting to put his Pokemon powers to good use and modify them to have some healing factor capabilities instead of just provoking mayhem all of the time. His lizard pet Stealthy was seen eating oranges and grapes in a plate provided to him by Hydro.

"Injections aren't goanna be that beneficial but herbs on the other hoof would be practical if I want to modify my Pokemon moves." Hydro told himself as he continued to study his book.

At first, everything seemed very peaceful with the little colt's studying process but suddenly, the doors of his bedroom were pulled open. Hydro looked behind him to see his dad standing at his front doors wearing his ninja outfit, and a pink scarf.

Hydro immediately ceased on his studying process and closed his book. After that, he got off his seat and stood up straight in from of his dad.

"Father." Hydro said greeting him with a smile. "I assume that training is going to instigate now?" He asked.

"Correct." Greninja replied to his son with a nod. "I've finished my shift today, now, we have the time to train on your Pokemon moves as well as your strength." He added.

"Yes father."

"Good, now come on, we don't have all day." Greninja told him.

Hydro nodded and made his way to the front doors of his bedroom. When he got to them, he and his father both departed to town where the training will commence. Even Hydro's Iguana lizard pet Stealthy was eager to see this training session so, he slowly began to make his way to Hydro's couch to watch the news on TV.

Zephyr Heights 9:00pm

In a part of town in the luxurious city of Zephyr Height, a large intersection area of the town was seen closed off by ten pegasus guards as well as police officers who were preparing for the training session of Hydro by Greninja. Sunny, Hitch, Izzy, Pipp and Zipp were there to watch the scene, Pipp has pushed herself to the front of the crowd so that she can corroborate that Hydro does not get hurt in today's training session. TV reporters and journalists were seen gathered here as well.

"We are live now to see Equestria's hero Greninja to train his son Hydro Petals once again today. Will the prince be able to beat his father this time? Or, will he get defeated again?" The female reporter said through the camera.

"Give it your best shot baby!" Pipp cheered for her son.

"Be careful!" Sunny exclaimed.

"Watch your every movements!" Hitch instructed.

"Remember not to panic!" Izzy exclaimed.

"Remember all of the tricks aunty Zipp has taught you to confuse your dad okay?" Zipp exclaimed.

Once Greninja and Hydro both made it to the centre of the town, Greninja took a couple of steps away from his son before starting the match. Once the ninja pony was at least a meter away from him, he got into a battle stance, so did Hydro.

"You ready son?"

"Ready when you are dad!" Hydro replied in a confident tone.

"Alright, training begins now!" Greninja announced. "You can have the first move." He told him.

Hydro nodded before pressing his hooves at the sides of his flanks summoning two water shurikens in the process. He then threw the two of them towards his dad.

When Greninja noticed the incoming projectiles, he sliced them with his cut attack, causing them to explode in the process, creating a huge white mist.

Hydro took this chance and ran towards the giant mist where his father was with his hooves glowing brightly in white indicating that he's going to use his aerial ace attack. When he got to the mist, he jumped through it and kicked his father in the chest sending him skidding backwards a few feet.

"Not bad, lets see how you go against this." Greninja said as he summoned a dark purple blade in his right hoof, this was known as his night slash attack. After that, he charged towards his son.

When Hydro noticed this, he summoned two light blue kunais in his hooves which was known as his cut attack. After that, he charged towards his father with his attack ready as well. When both father and son got to each other, they clashed and began to strike each other endlessly with their attacks but, none of them were able to land an attack on one another. After seven more clashes, Hydro decided to think out of the box by jumping upwards on top of a street lamp and aimed his hooves forward towards his father, then, he launched his Hydro pump attack towards him.

Greninja immediately took action and jumped back, avoiding the attack in the process. After that, he placed his hooves on the sides of his flank and threw two water shurikens towards his son Hydro.

When Hydro noticed this, he jumped off the street lamp post and the water shurikens flew and disappeared into the skies. Once he landed onto the floor, he cloned himself into ten with his double team attack and jumped into the air along with them, preparing a move in the process.

Greninja wasn't going to give him the chance to do so, so, he cloned himself into ten with his double team attack and jumped upwards with his clone in a rapid pace. Greninja's clones attacked all of Hydro's fake clones, causing them to disappear upon impact. However, the real greninja planted a palm strike in the real Hydro's chest.

"Augh!" Hydro grunted. After that, the pegasus colt landed roughly onto the floor, while Greninja landed on his hooves.

"You give up?"

Hydro however was not going to submit to his father that easily so instead, he pushed himself back up with his hooves glowing white and lunged at him, attempting to hit his dad with an aerial ace attack. Unfortunately, his dad Greninja reacted quickly and grabbed his hooves, after that, Greninja threw Hydro halfway across the intersection.

"Gah!" He grunted as he rolled on the floor but, he was still fine nonetheless despite having some injuries sustained on him from the rough falls. The young colt pushed himself back up before flaring at his father. "No choice, I've got to use my battle bond powers." He told himself.

Then, the pegasus prince began to grunt and groan in attempt to activate his bond phenomenon powers but unfortunately, he hasn't reached his full potential yet meaning that, his ability was not able to activate. Hydro then decided to cease on this useless attempt and fight the old fashioned way.

"Gah! This is useless, I'll just continue to fight with my moves!" Hydro exclaimed summoning his light blue kunais in his hooves again. After that, he charged towards his father.

When Greninja noticed this, he summoned a large white blade in his right hoof and awaited for his son to get to him first.

Once Hydro got to his dad, he jumped upwards and attempted to slice him with his cut attack.

"Yah!"

Unfortunately, Hydro has made a terrible move when his father spun himself around and slashed his blades with his cut attack in a powerful way. The contact sent Hydro flying backwards and rolling onto the floor, with his kunais broken.

"Grr." Hydro growled as he pushed himself back up again. After that, his hooves glowed white again and he charged to his father once more.

When Hydro made it to his dad, he attempted to hit him with his aerial ace move but however, his dad dodged the attack by cloning himself.

"Grr, I'm sick of this childish trick!" Hydro grumbled as he began to attack all of the clones rapidly with his aerial ace attack by punching and kicking them. After kicking seven of the clones, the pegasus prince went to the last one on top of him which he assumed was his father, he then attempted to hit him with a punch.

When Greninja noticed his son's plan, he raised his glowing right back hoof in the air before slamming it onto his head.

"Gah!" Hydro grunted as he crashed onto the hard floor.

The exertion has made the entire audience gasp at the sight, Greninja then landed on the floor on his hooves and looked at his fallen and injured son Hydro with his hooves crossed.

When Hydro saw his dad in front of him, he placed his hooves on the floor and attempted to push himself back up and fight again but unfortunately, the young colt has lost all of his strength and he collapsed onto the floor again.

"I-I accept defeat." Hydro mumbled between breaths.

At this rate, Pipp pushed her sister Zipp out of the way and went under the police line. After that, she ran to her son Hydro.

"Baby! Are you okay?" Pipp asked as she held her son in her hooves with a concerned expression.

"I-I'm okay mom." Hydro said between breaths due to his injuries.

"Alright Greninja, that should be enough for today." Pipp said sternly.

"You got it Pippy, still son, I'm impressed in how smart and strong you've become." Greninja said in a proud tone.

"Th-thanks dad." Hydro said with a weak smile. After that, Pipp turned to the crowd of ponies.

"Alright everypony shows over, go back to all of your homes and sleep!" Pipp demanded sternly.

The crowd of ponies obeyed princess Pipp's command and began to walk back to their homes to rest including Sunny, Izzy, Hitch, and Zipp who were all beyond astonished at how strong Hydro had become. But unfortunately, he lost to his father once again.
