Hello everyone and welcome back to Rainbow Union. I hope you all are doing well and again thanks for all the support for this. This was probably one of the hardest chapters I have ever written just because I wanted to put in everything, but as always I hope you all enjoy this.

Chapter 15: Operation Legends

The Ultra Guardians on each of their respected battle fields looked up in surprise. Standing before them and their Pokémon were the legendary Pokémon from their respected region. In the Team Magma Room, Blaziken and Charizard tried their best to avoid Groudon's attacks such as Flamethrower and Ancient Power. In the Team Aqua Room, Primarina was barely able to get it and Tsareena out of the water avoiding the raged Kyogre's jaws before jumping back in to battle the large water beast. In the Team Galactic Room, Togekiss and Vikavolt were having their own struggles flying around Giratina and firing off their own attacks which barely scratched the dragon as it looked back at them and used its own attack to blow them away. And in the Team Flare room, Braixen and Luxray avoided the giant vines Zygarde created to use to attack them all the while Lysandre laughed.

"You see you are no match for the power of Zygarde, and you should consider yourselves lucky I didn't catch the other one, otherwise the results would be catastrophic." He said while Clemont and Serena gritted their teeth in frustration as the alternate universe Ash looked on holding onto his Greninja wishing he would do something. Back in the Team Magma room the battle still continued between Blazakin, Charizard and Groudon, with Groudon gaining the upper hand with the two fire types.

"Alright then!" May said as she stepped forward. "Blazakin it's time!" She said as Blazakin returned to her side with Charizard floating back over to protect Kiawe. When the Alola native looked up she could see a familiar circular stone hanging from the tip of her bandana as his eyes widened.

"A key stone?" He said to himself as the Key Stone and Blazakin glowed as it turned into its Mega Evolved form.

"Let's go Mega Blazakin!" May shouted as Blazakin charged at the legendary.

Back in the Team Aqua room the underwater battle with Primarina and Kyogre continued with Primarina trying her best to avoid the legendary Pokémons attack without being swept up in its current. Mallow and Lana had formed a plan that could work as they just had to get Kyogre out of the water. Mallow looked at her childhood friend and gave a nod as Lana looked out over the large pool of water.

"Primarina now!" She shouted as her partner sprang up from the water with Kyoger leaping up as well its jaws opening the moment in front of the pair looking like something from those ocean documentaries of large Sharpedo's chasing Dewgons.

"Now Tsareena, Magical Leaf full power!" Mallow cried out as several bright leaves appeared in front of Tsareena as she aimed them down on to the legend as they were able to hit it as it looked like it was going to head down into the water its eyes groggy dazed from the attack.

"Is that all you got girly?" Archie asked as Kyogre's eyes burst open surprising the two attacking Pokémon. "Now use Ancient Power!" The team leader commanded as Kyogre blasted both Tsareena and Primarina out of the sky sending them both crashing outside of the pool.

In the Team Galactic Room, Dawn and Sophocles were still struggling against the giant Giratina with Togakiss being knocked out and Dawn having to bring out Mamoswine in its place.

"Alright, Mamoswine use Ice Shard!" Dawn said as her huge ice type fired shards of ice towards the dragon. The Sinnoh coordinator then looked at Sophocles and gave him a nod the young inventor nodding back.

"Vikavolt multi Zap Cannon blast on those ice shards!" Sophocles yelled as his partner fired off several electric shots at the ice shards as they connected to form electrical ice shards hurling towards the large dragon. However it was ineffective due to the massive dragon's size.

"Pathetic." Cyrus said as he looked up at the dragon. "Now Giratina use Shadow Sneak and plunge them into darkness!" He said as Giratina let out a roar and disappeared into the shadows.

"Where'd it go?" Sophocles asked.

"I don't know, but stay focused it could pop up anywhere?" Dawn said as both Mamoswine and Vikavolt also were looking around the room. Just then from underneath their feet a black dot appeared.

"Now!" Cyrus said Giratina emerged from its massive shadow knocking both of Dawn and Sophocles's Pokémon off their feet as they struggled to get back up.

Meanwhile in the Team Flare room, Braixen and Luxray continued to dodge the possessed Zygard's vines that it had unleashed.

"Braixen use Flamethrower!" Serena shouted.

"And Luxray use Wild Charge!" Clemont shouting as well the two trying to destroy the vines that now covered the entire room. But even as they destroyed the ones that were heading towards them they didn't see the ones coming up from beneath them knocking them down as Serena and Clemont gasped. Just as more wild vines were heading towards them, they were knocked back by a surprise Water Shuriken attack as all three trainers looked to see Ash, caring Graninja on his shoulders as the black colored frog had its arm extended before collapsing again.

"It doesn't matter what you do, you are no match for our legendary Pokémon." Lysandre said as he spread his arms out. "Behold!" He shouted as several hollow screens appeared as Serena and Clemont looked to see the rest of the Ultra Guardian's Pokémon knocked out as their trainers were holding them close. "You should've realized by now, you are just children nothing more. You may have been lucky defeating our other selves but we are different. We are Rainbow Rocket, and all of us will have our dreams in this world be a reality!" He said as he raised his arm as Zygarde brought up a huge vine ready to crush the trio. But just then a huge light appeared above them, the same thing going on in the other rooms. Everyone looked up at the ceiling above them as even the legendary Pokémon stopped their attack. The lights then floated their way down before the Ultra Guardians as four Pokémon appeared before the four pairs. In the Team Magma room, a Pokémon with a purple shell appeared before Kiawe and May as the Alolan native's eyes widened.

"No way, that's Tapu Fini." He said. In the Team Aqua room a Pokémon that looked like it was wearing a red wooden hat and bull horns on top appeared before Lana and Mallow.

"Tapu Bulu." They both said in awe the bull horned legendary staring down the legendary Pokémon of the Ocean. In the Team Galactic room a Pokémon with Pink hair sitting in a pink shell that's surface resembled a face of a bird appeared before Dawn and Sophocles.

"That's Tapu Lele." Sophocles said in awe as the pink haired Pokémon floated near Giratina's face. And in the Team Flare room a Pokémon whose armor and features colored yellow and orange appeared before both Serena and Clemont.

"Woah who's that Pokémon?" Clemont asked.

"Let me see." Serena said as she pulled out her very own Rotomdex, Professor Sycamore gave her. After scanning it, the information came up in it. "It says here its Tapu Koko, one of the four island guardians of Alola." Serena said as Tapu Koko approached the other world Ash and locked eyes with him

"So the legends were true then." Lysandre said. "Four guardians that protect the region of Alola." He said. "But it matters not, they are no match for true power!" He said as Zygarde let out a terrifying screech. Tapu Koko looked up at the huge red serpent before looking back at the other Ash. He then held out its claw as something was hanging on it as Ash took it revealing to be a white bracelet with a yellow crystal with strange markings in the middle of it.

"You're giving this to me?" The other Ash asked as Tapu Koko nodded. "Okay." He said as he put the bracelet on. Back in the other four rooms, Tapus, Lele, Bulu and Fini gave similar crystals, to Lana, Kiawe and Sophocles.

"Wait…" Lana said after putting the crystal on her Z Ring.

"This is Tapuniam Z." Kiawe said looking at his.

"Just like Professor Kukui used." Sophocles said as they all remembered the battle between Tapu Koko and Pikachu in the exhibition match. At the same time all four crystals glowed as the holders all took positions.

"Alright, I don't know what's going on but I'm ready." The other Ash said as Serena and Clemont stood by his side.

"We're with you too Ash." Serena said.

"To the end." Clemont added. In the Team Magma room, May stood next to Kiawe ad the two nodded to each other, the same with Lana who was holding the crystal, along with Mallow, and Sophocles and Dawn.

"Lets do it!" All four said as the four tapus guided their respected partners through the moves.

"I can feel it." Kiawe said as he and May went through the moves.

"The spirit of the Alola region." Lana said.

"It sure feels nice and warm." Sophocles said.

"And I can feel Tapu Koko's strength flowing with me." Ash said as all of them were now in the pose. Just then in each room a huge light appeared as the four tapus flew above them, everyone looked to see they were giant body's of light as they all went into their defensive position taking the forms of giant tiki head and placing themselves on top of them, as all four evil team leaders looked up in shock.

"Alright then let's do it!" Ash said he said as he and the others finished the move along with their respected Tapu partners.

"USE GUARDIAN OF ALOLA!" They all shouted as with their giant fists, the four Tapu's smashed the legendaries into the ground as their users were knocked back hard by the force the attack let out. When it concluded the large bodies of light disappeared and the Tapu's opened their shells as, everyone looked in their respected rooms to see the legendary they were fighting against were knocked out as well as the team leaders.

"We did it!" May shouted giving a high five to Kiawe as Blazakin and Charizard did the same thing. In the Team Aqua room, Mallow and Lana jumped for joy as their Pokémon looked on relieved that the fight was finally over. In the Team Galactic room, Dawn and Sophocles collapsed on the floor exhausted by the fight as their Pokémon came to comfort them. And in the Team Flare room the other world Ash stood with Serena and Clemont taking in what just happened before them, as the red Zygarde slowly turned back to green.

Clemont suddenly remembered what they came into the room for and opened up the hallo-screen on the control wrist he had and began scanning the room until he found what he was looking for. On the other side of the room where he walked up to, there was a hidden door as he opened it to reveal a button as he pressed on it. He then opened up the other one that came with his Ultra Guardian suit.

"Ash are you there?" He said as Ash appeared on the screen.

"Yeah we're here, we could hear a lot of noise are you okay?" Ash asked as Clemont nodded.

"Yeah, we're fine, hey listen did something happen to the barrier's in front of the door?" Clemont asked.

"Yeah, looks like one of the barriers flickered and turned off." Ash said as Clemont smiled.

"That's great, I'll check in with you when we get back down to the lobby." He said as he then contacted the others. "Hey guys, look for a secret compartment door, you should be able to find a button to turn off the barrier blocking the door. The other Ultra Guardians in their rooms got the message and began searching until they found what they were looking for and each pressed the button. Meanwhile back in the lobby, Ash, Lillie, Cilan, Iris, Bonnie and Max looked to see the barrier on the door had disappeared as a look of relief were on their faces.

"They did it." Lillie sad as Bonnie and Max high fived each other. But then the door began to open as the four trainers stood ready while Bonnie and Max stood behind them.

"Alright you guys, get ready for whatever is coming at us." Ash said.

To be continued….
