(Next Day after Lunch)

"Yesterday we talked about Mega Evolution. There was specific focus on Charizardite Z. So Ash after a day's thought have you made your decision?" Dragon Emperor asks Ash.

"I gave it a long thought. Both me and my Charizard feel that using this mega stone is the right way forward. So we have decided to do it." Ash replies.

"Very well young man. Your decision is a brave and an admirable one. I respect the courage shown by the 2 of you. Don't worry I am sure you will figure it out. But that is for a later time. Today we discuss about the mechanism of Z moves. How do Z moves power up a Pokemon? Why do we need to strike a particular pose for a Z move to work? What are the different classes of Z crystals? All these will be covered in today's class." Dragon Emperor says.

"Cool. Can't get to get started." Ash says.

"Now you have seen my Hariyama's Z move all out pummeling when we practiced dodging. Tell me what do you remember?" Dragon Emperor says.

"Well you were doing some kind of a dance. Then a certain glow engulfed you which then became a beam of energy which I am guessing was Aura. This energy then entered your Hariyama after which it was able to use the Z move." Serena says.

"Very good. Now let's start from the basics. There are 4 things necessary to perform Z moves. First thing you need is a Z ring. The second a Z crystal. Thirdly you need to be able to correctly perform all the required poses needed for the successful transfer of Aura energy. Finally you need a bond of complete trust having full synchronization with your Pokemon." Dragon Emperor says.

"OK. But what I have a question Dragon Emperor?" Ash says.

"What is it Ash?" Dragon Emperor asks.

"Well I just wanted your opinion on which one is better. Mega Evolution or Z moves?" Ash asks.

"Interesting question. The answer is that both have there advantages and disadvantages. Mega Evolution raises a Pokemon's attack power, Endurance, Defensive power and also induces other changes like change in type. Whereas Z moves give it's user an exceptional increase in power to perform one move in order to deal critical damage to an enemy. You must use whichever suits your Pokemon and the situation the best. Does this answer your question?" Dragon Emperor asks. Ash gives a nod to gesture to Dragon Emperor to continue.

"Now continuing from where we left. Now several people has classified Z moves in different ways. We shall be learning the classification of Z moves which has been followed in the order of the Pokemon classification known as the Grant Crystal Classification Scheme. According to this classification there are 2 categories of Z moves. In the first category the Z moves are differentiated by the type of the Z crystal. In simpler words here the Z crystals differ from each other based on the compatibility with their type." Dragon Emperor says.

"That's right. I have heard that there are 18 different Z crystals with 1 crystal being for 1 type. Like an Electrium Z for a electric type and a Darkium Z for a dark type etc." Ash says.

"Correct. Your research on Z crystals is correct. Most common ones are Type Specific in nature. However it was soon observed that there were certain Z crystals which were Pokemon specific. However we shall talk about those crystals a little later. For now we focus only on Type Specific crystals. Now would any of you care to venture a guess as to why the specific poses are needed to perform a Z move?" Dragon Emperor asks the duo. Both Ash and Serena think for a moment then nod their heads indicating that they can't guess.

"Alright now listen here. Have any of you heard about Aura Chakra points?" Dragon Emperor asks.

"I haven't." Serena says.

"The name seems familiar but I can't remember where I exactly heard this before. Give me a second will you?" Ash says before closing his eyes. His mind is racing when suddenly his thoughts rest on Riley and his Lucario.

"Of course. I met a trainer in Sinnoh known as Riley who had a Lucario. His ambition was to become an Aura guardian like a Sir Aaron. He told me and my companions about certain entries he found in Sir Aaron's diaries. One of the things mentioned were Aura Chakra points. Though he didn't tell me anything further." Ash says.

"I see. You're quite lucky Ash to have actually come across this term before. Any way the thing is that in the body of a Pokemon and a human's there are 7 Chakra points. Where these points are located I will tell you later. But for now know that these 7 points are vital nodes which are essential in controlling the network of Aura that flows through a living body. In fact one of the reasons why Pokemon and human trainer can bond the way they do is because they have the same number of Chakra points as the other. This gives humans higher compatibility with Pokemon unlike other Animals or Plants whose Chakra numbers differ." Dragon Emperor says before taking a sip of water.

"Well the thing is that the Z ring is different from the Key Stone used during Mega Evolution. Though both are Power up Phenomena's both have very different mechanisms. Always Remember. A human's Aura can take the form of any Pokemon's Aura. Each Pokemon type's Aura has it's own characteristic wavelength bandwidth. In Mega Evolution the Key Stone takes care of translating the Human trainer's Aura to the bandwidth of the Pokemon's type. This is not the case in Z moves. In Z moves the pose that we strike puts specific pressure on different Chakra point to ensure that the Aura that the human is going to transfer into the Pokemon for the performing of the Z Move corresponds with the bandwidth of the Pokemon which is going to perform the Z Move."

"Then what is the role of the Z Ring and the Z Crystal?" Serena asks.

"Do you remember I told you that every Pokemon's attack is associated with an individual strand in it's Class DNA?" Dragon Emperor asks.

"Yes we do what of it? Every move a Pokemon can perform has a unique strand in the Class DNA." Ash asks.

"Every Z move is based on the Pokemon's type. For example Gigavolt Havoc is a Electric types Z move. But if the electric type doesn't have the genetic information needed to perform this move it will not be able it. Here is where the Z crystal comes in. Z crystal temporarily provides the Pokemon with the genetic information needed to perform that particular move." Dragon Emperor replies.

"What about the Z Ring? What is it's use?" Serena asks.

"The Z ring acts as a stabilizing agent to ensure that smooth transition of the Aura power takes place from the Trainer to the Pokemon." Dragon Emperor says before pausing.

"But I don't recall anything like this happening in the mechanism of mega evolution. There also we give huge amounts of Aura power needed for the Pokemon to Mega Evolve. I don't recall anything like a stabilizing agent being present there." Serena says.

"Observant as always I see. The reason is again the difference in the mechanisms. But this time I will let you answer your question for you. Tell me Ash can a Pichu use a move like Volt Tackle?" Dragon Emperor says.

"No it can't. A Pichu can barely control large amounts of electricity. So focusing the energy into a move like Volt Tackle is impossible." Ash says.

"You are right. Yet Pikachu can. Why is that Serena?" Dragon Emperor says.

"Because it has evolved so it's body and mind can handle the large amount of power needed to perform Volt Tackle." Serena replies.

"Exactly. Same is the case in Mega Evolution. In Mega Evolution the entire genetic makeup of the Pokemon undergoes a mutation which gives it another evolutionary stage. This higher evolutionary stage enables it to withstand that high level of Aura power that it receives from the trainer during the Mega Evolution. However in the case of Z moves we provide an exceptionally high level of power to a Pokemon which has not evolved. To ensure no harm comes to the Pokemon while it is receiving the high level of Aura Power from it's trainer to perform a Z move the Z ring acts a stabilizing platform." Dragon Emperor replies.

"But that would mean that Mega Evolution is better than Z moves. Not only is there no need for any poses but the mechanism is also more evolved and complex that the latter's." Ash says.

"You are right to a certain degree. Mega Evolution does give a more overall benefit instead of just powering up 1 move but it also has it's limitations. The biggest being that for a Pokemon to Mega Evolve it needs to be in it's final evolutionary stage. However a Z move can be used by even a Pokemon which has not evolved completely." Dragon Emperor says.

"Cool." Ash says to which Dragon Emperor chuckles.

"What about the other type of Z crystals which are Pokemon specific?" Serena asks while consulting her notes.

"Oh right. Good that you reminded me for I almost forgot. Now what I told you was about Type Specific Z moves. The other type of Z crystals are Pokemon specific. You see whether it is Pokemon or human or this planet everything is in a constant phase of change and evolution. This is true in the case of Z crystals as well. It seems as time passed we started to find Z crystals which were not only type specific but Pokemon specific as well. A good example of this is a Snorlaxium Z." Dragon Emperor says.

"Snorlaxium Z! You mean that Snorlax has a Z crystal which is specific to it. That is cool." Ash says thinking about his own Snorlax.

"Yes. Now to get to the crux of the matter. The difference of type specific Z crystals and Pokemon specific Z crystal lies in it's genetic programming. Now keep in mind that the move a Pokemon can perform is dependent on whether it has the genetic strand needed to perform that move. In Pokemon specific Z crystals a little mega evolution is performed." Dragon Emperor says.

"You lost me completely." Ash says.

"Same here." Serena replies.

"OK then let us understand through an example. Consider Snorlaxium Z. One of Snorlax's best known Z moves is Pulverizing Pancake. This move can't be performed if your Snorlax can't perform Giga Impact because Pulverizing Pancake is the evolved Z move based on Giga Impact." Dragon Emperor says.

"So the Z move is based on whether a Pokemon has mastered the base move on which the Z move is based on. That's interesting." Serena says while taking down notes at breakneck speed.

"But one thing I don't get. Why did you say that a little Mega Evolution is performed before?" Ash says.

"Because when a Z move happens with a Snorlaxium Z the genetic information in the Z crystal triggers a temporary mutation in the class DNA of Snorlax on the strand which controls Giga Impact. After the Z move has been completed the pulverizing pancake strand reverts back to it's original Giga Impact strand form." Dragon Emperor says.

"So that's why a little Mega Evolution. Nice. Very Nice." Ash says with his body shaking in excitement.

"I can't wait to get started." Serena says thinking of her Z moves as well.

"Very well then. Let us begin." Dragon Emperor says in his characteristic calm and composed cool tone.

(Meanwhile in Pallet Town)

"Good thing Grace told me what happened. Soon I shall be in Kalos and get to know what Ash and Serena have been up to and what is this deal with this Dragon Emperor character." Delia says in a worried tone while packing her suitcase.

"Mime Mime Mr. Mime." Mr Mime says while agreeing.

"Of course. Just like Ash. Rash and unpredictable as always. Doesn't think for a second before going on a journey with someone he barely knows." Delia says in a little angry tone.

"Mime Mime." Mr Mime says in calm and reassuring tone.

Delia takes a deep breath. Then she turns to Mr. Mime and says "You are right. Maybe I am just over reacting. Still it will be good to see Grace after all thee years. What do you say Mimey? Ready to go an adventure with me?"

"Mime Mime." Mr. Mime says in an ecstatic tone.

"OK then let's go. Our flight is in 2 hours." Delia says while picking up her suitcases and closing the lights of the house before locking the door.

She enters the cab along with Mr. Mime after putting all the luggage in the trunk of the cab.

'I hope you are safe Ash and Serena. Wherever you are.' Delia thinks to herself as she looks at the ever changing scenery in the black of night while the car is moving.
