After he was explained about Cyrus, Team Galactic and even the special bond that he'd have with Riolu one day, Kjolmar was asked about his mega stone. "Well... There is two parts to that. First you something called a key stone, like the one you can see in my watch right here." He showed Aro how the key stone was clicked into the watch. 

"Then you need the right mega stone for your pokemon to have it mega evolve." 
Kjolmar realized Aro wouldn't have asked about it if he had known all of this. "My apologies. I wrongly assumed every trainer was told about this at the start of his quest. At least, that's how it happens in Kalos. Perhaps Rowan knows more about it but he kept it to himself until he fully understands it? Or maybe that old man is becoming senile after all. Hehe, don't tell him I said that."

"Every pokemon that can mega evolve, has a different mega stone." Kjolmar continued.
"For example, Gyarados is wearing a collar with gyaradosite. A Gardevoir would wear gardevoirite, and so on."

Kjolmar glared at Apollo. He couldn't quite hear him through telepathy yet but he just knew it would happen one day. "Actually, mega evolving also requires a strong bond between a trainer and his pokemon, similar to Riolu's telepathy. Perhaps Luna would be able to mega evolve if you found the correct mega stone, I don't know all the pokemon that can mega evolve. But if that is the case, I can gladly ask my region's professor to send us an extra keystone for you."

After Aro's egg hatched into a Chimchar, the team was on their way to Floroma town. But before they got there, a net captured Noibat and a male Pyroar grabbed the net with its mouth and started running. 
"A Pyroar in Sinnoh?" Kjolmar gasped. "Don't tell me that he followed me all the way here?"

The group chased the Pyroar who was kidnapping Noibat. It led them straight to someone who looked like a trainer, dressed in red. "So that Pyroar IS yours! What are you doing here, Han?"
The boy chuckled. "I went to find you in Lumiose but there was no one there. Then I encountered your sister along the road and tricked her into telling me where you went. Obviously I won't rest until I've taken your gyaradosite and then beat your Gyarados. So how about a trade? You get Noibat back in exchange for your gyaradosite. And afterwards we battle."

Kjolmar was still carrying Apollo in his arms. He whispered something to him. "Okay buddy, here's what we are going to do. Telepathically tell Luna that Aro should make his way around that guy and block him from the other side, so he won't be able to escape. I'll close in from the front."

While Apollo jumped from his arms, Kjolmar slowly walked up to Han. With Han being completely focused on Kjolmar, Apollo saw his chance to use telepathy towards Luna. Kjolmar looked Han straight in the eye while approaching him. "I have a better idea. How about I don't give you anything but we'll battle without using mega evolution. If you win, you get the gyaradosite. If I win, you leave us alone."
Han shook his head. "As if I'm going to take any chances with you. Pyroar is powerful but so is Gyarados, I've experienced that more than once. The deal is simple: the gyaradosite for Noibat's safe return."

Noibat clearly got fed up with the situation and started to hit the net he was captured in from all sides. It screeched loudly while doing so, becoming more and more enraged. Then it started to glow with a bright light. Everyone looked at Noibat and gasped. "Is it...?"

When the light faded, the net broke and Noibat had evolved into Noivern. It pinched its eyes at Han and started flapping its wings, creating a whirlwind that blasted Han away into the distance. Pyroar seemed shocked and started to run after his master.
