Strike, Flare, and Panchie were ready to go back to Seashore Cave but first they headed to the guild. They remember someone was gonna accompany them, they were curious who it was gonna be. The three walked in the guild and saw Gardevia was already waiting, next to her was a Gallade.

"I am glad to see you three. I hope you had a good sleep" Gardevia said

"We sure did. Why is a Gallade here?" Strike asked

"This is my brother, Bllade. He will accompany y'all in the Seashore Cave to investigate the Dark Stones" Gardevia explain

"To think I'll have to accompany a human again after so long" Bllade said

Strike suddenly was caught in surprised hearing Bllade's word. Bllade's words sounded like Panchie and weren't the only humans that were here.

"Alright, let's no waste time and go to the Seashore Cave and don't worry about the pokemons in the cave, I'll take care of them while you three lead the way" Bllade said

The trio nodded and headed to Seashore Cave while Bllade followed.

-----------------------------
Mystery Dungeon: Seashore Cave

As the four headed in the mystery dungeon, the same usual pokemons that appeared last time the trio came to the cave appeared but this time Bllade was fighting them, he took care of them all quickly without breaking a sweat. It wasn't surprising for the trio as Bllade had experience with battle considering he's Gardevia's brother.

The four got deeper and were then in the room where many Dark Stones were but by surprised. There were no Dark Stones, all of them were no longer on the walls, the room just was just a empty dead end.

"Um, what happened? This is the room where we saw a lot of Dark Stones, right?" Flare asked, he looked around confused

"Are you sure you kids weren't seeing things?" Bllade asked, thinking this is a joke

"No, this is the room where we saw many of them. I'm sure it is, I can even recognize it even without it" Panchie said

"You don't think the Pokemon that's using the Dark Stones got here before us, right?" Flare asked

"But how could they take it without no one noticing? There were too many for on" Panchie said

Suddenly the whole room shaked as a part of the room begins to crack until a Onix appeared. It wasn't a regular Onix, it was a Onix being taken over by a Dark Stone on its head.

"There's your answer, looks like they might use Onix to get the Dark Stones out of the cave. Also the Onix is affected by a Dark Stone, careful" Bllade

"In that case we will have to fight it. This is a good chance to understand the Light Bracelet once we knock this Onix out" Strike said

The trio start getting too while Bllade stayed back to observe the three in action. Onix roars as it begins swinging his tail at them. The three dodge and Strike begins attacking with thunderbolt, shocking the Onix before it shake it off and headed straight towards him. Flare used flamethrower  from the side but it barely affected the Onix and made it go after him at a quick until it wrapped his body around Flare.

"Aaaah, help!" Flare shouted, struggling to free himself as Onix was slowly gripping

"I'll save you Flare!" Panchie shouted.

Panchie jump towards Onix and punch his face. The Onix lost grip of Flare, giving Flare a chance to escape from him.

"Are you okay, Flare?" Strike asked

"Yes I am. Thank you, Panchie" Flare said

"Your welcome. Ow, punching the onix really hurt. I don't get how pokemon can punch a rock without getting their fist hurt a lot" Panchie said, rubbing his fist.

"Gotta get used to it, plus we got no time to complain. The Onix is about to do something!" Strike called out

The Onix roars as it begins charging a Hyper Bean and immediately shoots at them. The three separated and try staying away from Onix's hyper bean. Strike tried stopping Onix with thunderbolt but it only slowed it down a bit before it suddenly stop and begin radiating dark energy from the Dark Stone. They could feel a strong force coming from Onix as it suddenly used a dark version of  Hyper Bean only this time it was more stronger and bigger and it was aiming towards Strike. Strike begin running, he couldn't find a chance to attack Onix, who's Hyper Bean slowly was catching up to him. Flare tried using flamethrower but it didn't flinch Onix, Panchie tried Drain Punch, it didn't flinch it either especially while draining its energy. Flare and Panchie continue attacking it trying to stop or at least slowed down Onix.

Strike kept running trying to avoid Hyper Bean, suddenly he tripped and felled and suddenly the Hyper Bean was already closed him. Strike couldn't get up quickly and closed his eyes, not ready to take the hit. Suddenly when Onix's hyper bean was on Strike, the Light Bracelet began to glow and created a light barrier around him, protecting him the hit. He suddenly open his eyes and noticed a barrier in front of him absorbing Onix's dark hyper bean.

"Woah, is the Light Bracelet doing this?" Strike said, he sees the Light Bracelet glowing "Jirachi didn't mention the bracelet having any special ability"

"Strike is somehow being protective by a strange barrier. How are you doing that, Strike?!" Flare asked being awe

"I-I don't know but it is coming from the bracelet" Strike responded

Onix stopped using hyper bean and was caught surprised seeing Strike still standing. Suddenly the Light Barrier that absorbed beging charging until it suddenly shot a weaker hyper bean that didn't flinch

"That was it?! That was so anticlimactic coming from a bracelet that just save me!" Strike shouted in disappointed

"Now I'm getting worried if these Light Bracelet will actually really help us" Panchie said

Onix was ready to attack Strike while he was distracted until he was knock out by Bllade's fast and strong punch.

"Can't say that was the best fight but you're still learning since you're a human. Now the stone off the Onix" Bllad said

"How? I was never explained how to do this?" Strike said

"Get closed to the Dark Stone on the Onix and aim the Light Bracelet at it" Bllade explain

"I'm not sure how you exactly aim a bracelet at something but alright" Strike said and cautiously walk to the Onix "alright, Light Bracelet do your thing"

Strike holds his arm with the Light Bracelet out. The Light Bracelet suddenly radiated to the Dark Stone and made it vanish in thin air.

"Did it actually work?" Strikes asked until he heard the Onix snored "I'd say that's a yes"

"That was a tough Onix, probably more tougher than the Two Bibarels" Panchie said

"Looks like each time we see these pokemon with dark stones, we learn more of what they do. Each pokemon seemed to have the ability to use dark evil version of a move" Strike said

"It is scary how much power these dark stones have but with the Light Bracelet and you two, we have a high chance of figuring out the one behind this and end this" Flare said

"We need to go back to Gardevia and explain what happened here" Bllade said "since I also got an idea"

The trio nodded and headed out to the exit of Seashore Cave with Bllade.
