When Ash greeted the class for the first time, it was a slightly different one from canon. "Hi, my name's Ash, from Pallet town. These are my buddies Greninja,"
"Greninja"('my name is greninja, as you can see')
"and Pikachu,"
"PikAchu"('My name is pikachu, obviously')
Then they all greeted Ash, like canon. But Kiawe thought Ash was strong, and, being a battle-maniac, challenged him. But Professor Kukui came and he ended up not being able to battle him yet.
"Morning class," he said.
"Moooorrrning teeaaachhheeeerrrrr," said the class.(they took a while to say that :O)
"Today we are learning about bond phenomenon. It's when-"
"A person and a pokemon's bond is so strong it makes the pokemon temporarily evolve kind of. Unlike Mega Evolution or Primal Reversion, the transformation does not require any specific items, like mega and keystones for either the Trainer or the Pokémon to bond. So far, the only known
Pokémon to have this transformation is Greninja, like my Greninja. In this form, the strength of Greninja's legs are superior to that of an ordinary Greninja. Additionally, it gains the ability to form large-sized Water Shurikens on its back. Wow that took a lot out of me." Ash continued.
"It's GREAT that the new student knows what it is. How did you know?" Professor Kukui asked.
"Well I know it because I was the one who achieved it," answered Ash. Everyone was shooketh. The more you know.
"So you were the battler at Kalos? And you almost defeated Alain at the finals?"
Yep." said Ash, emphasizing the P."
"Well I guess it's time to do our daily battles." Professor Kukui said
While Ash was sleeping in his/Professor Kukui, Tapu Koko and Fini took his mega ring, made some modifications, and made it a mega and z ring. But Ash didn't know that they also left 2 Z Crystals with an infinite sign inside the watch compartment...
