You are focusing so much on one of THREE exclusive Z Moves the Pikachu family has, you need to think bigger than just Pikashunium.

"Ultra Guardians, it's nice to see you all in person again." Lusamine said as the six trainers entered the base with their Pokemon partners.

"Mother, what are you doing here?" Lillie asked in surprise. "We didn't miss a family dinner, did we?"

"No, I know I'm not always at home, but I would've remembered a family dinner." Ark commented. "Unless Hobbes forgot to say something."

"Relax you two, we're not here for a scolding, rather we're here for some gifts." Wicke said.

"Gifts, like those helmets? Are they finally ready?" Kiawe asked.

"No, we've had some other problems with them, so they aren't ready yet." Wicke said.

"If it's not the helmets, what are we here for then?" Sophocles asked.

"Well, we actually have gifts and a surprise." Wicke said, as a set of alarms went off.

"News will have to wait, we have an Ultra Wormhole opening up." Lusamine said, typing away at the computer. "Suit up, and we'll send you directions through Rotomdex."

"Ult Roger Lusamine!" All six said, running to their capsules.

Up in the air

"We're dealing with a larger Ultra Beast than you have ever faced Guardians, be careful and approach with caution." Lusamine said.

"Where is the Ultra Beast at Miss Lusamine?" Lana asked.

"That's just it, it's on the move and very fast, almost like a rocket." Professor Burnett responded. "We're going to have half of you break off and try to get ahead of it. Kiawe, Mallow, and Lillie stay on it. Ark, take Lana and Sophocles and try to get ahead of it."

"Wait, but splitting up means we'll be radio silent without Rotomdex.". Lillie said.

"I know, but this is the only way we can proceed." Lusamine said. "Be careful, we'll monitor your vitals from here."

"I knew we should have handed them out in class." Professor Kukui said, looking at the box next to him.

"Even Braviary couldn't catch up to them in time at this point, we'll have to hope they manage this without contact." Professor Burnett said, trying to remain calm.

Back with Ark's group

"Alright, I see it coming, everyone be ready." Ark said, seeing the Ultra Beast rocket towards them. "Garchomp use Flamethrower! Pikachu use Thunderbolt! Toucannon use Hyper Voice!"

"Vikavolt you use Thunderbolt too!" Sophocles called out. "And Metang use Flash Cannon!"

"Dragonair use Ice Beam!" Lana called out.

The six attacks collided in an explosion that stopped the Pokemon for a moment as it turned upright.

"Oh, that is big." Ark said, seeing it full height.

"By my calculations its nearly 31 feet tall!" Rotomdex exclaimed, not moving from his place on Ark's shield armor."

"Really didn't need to know that, Lusamine we need a plan!" Ark exclaimed amidst a panic.

"Keep it there, try and contain it and catch it, same as always!" Lusamine called out.

"Right, Pikachu use Thunderbolt!"

"Vikavolt use Thunderbolt too!"

The two bolts of electricity shot out, causing the giant Ultra Beast to begin falling to the waves below.

"That was great, it got really hurt by that, keep it up!" Rotomdex called out.

"Lana, we'll hit it with two Giga Volt Havocs, then once it's in the water freeze it in place." Ark said.

"Copy that Ark." Lana said.

"Toucannon go and find Kiawe and the others, we'll need them in case this doesn't work." Ark said.

"Cannon!" Toucannon cheered, flying off.

"Alright Sophocles, are you ready?" Ark asked, placing his Electrium Z in his Z Ring.

"Yep, now Vikavolt go grab Pikachu!" Sophocles called out, as the large bug flew over to grab Pikachu.

"With all our power!" Ark said.

"And all of our combined might!" Sophocles added.

"Use Double Giga Volt Havoc!" The two called out in unison.

Pikachu and Vikavolt were engulfed in electricity as they shot forward towards the giant Ultra Beast, slamming into it at high speeds, and engulfing it's entirety in sparks before crashing into the waves below.

"Lapras, Dragonair use Ice Beam! Briones use Icy Wind!" Lana called out from Lapras's back.

Ice began to slowly form around the Ultra Beast locking it into position as the others arrived.

"I'm impressed Ark, your plan actually worked this time." Kiawe said.

"Yeah, but it's not over yet." Ark said, looking at the ultra beast, "We still need to catch it and return it home."

"On it!" Mallow said, flying down with Flygon. "Beast Ball go!"

A beast ball slammed into the side of the Ultra Beast, encasing it in a red light before it was fully absorbed into the Beast Ball.

"Just in case, everyone but Sophocles ready a Z Move." Ark said, mentally including himself with Sophocles.

'Ding Ding Ding'

"Phew, we did it." Ark said, flying down with Garchomp and scooping it up. "Ultra Guardians, let's return to base."

"INCOMING CALL FROM MISS LUSAMINE!" Rotomdex interrupted, flying out from Ark's chest plate.

"Lusamine, perfect timing we just caught the Ultra Beast." Ark said.

"Great work Ultra Guardians, I'm sending you the location of where the wormhole originated, you can meet us there before heading back." Lusamine said, marking the location on Rotom's map.

"Alright guys, we're headed to the Wormhole first, follow me." Ark said, taking a mental note of where to go.

On the Western Shore of MeleMele

"Here we are." Professor Burnett said, typing away at her keyboard. "All we need to do is open the wormhole and we can send them home."

"That was some very fast work Guardians." Lusamine said.

"We're really getting quite good at this, aren't we?" Lillie said happily.

"Don't get too overconfident." Ark said, wincing slightly.

"Ark, are you okay?" Lusamine asked.

"I'm fine, just a bit of feedback from my Z Crystal." Ark said, looking at his Electrium Z, the cracks had spread, and were nearing the center.

"Ark, I don't think it's such a good idea for you to keep using that." Lillie said worriedly.

"Yeah, what did the Kahuna's say about it?" Kiawe asked.

"That using it might help, it might not, they aren't really sure." Ark said.

"And you're willing to risk your first Z Crystal on that?!" Kiawe exclaimed.

"Don't worry so much about it, our bet will still be on either way." Ark remarked calmly.

"That's, not what we're worried about." Kiawe sighed. "Let's just send this thing home. Ark what should we call it?"

"Ooh Ooh, I know! How about Celesteela!" Sophocles exclaimed.

"Sounds good." Professor Burnett said, activating the transporter. "Alright then Celesteela, have a safe trip back home."

The group watched as Celesteela rocked into the reopened wormhole, Magearna closing it after they had gone through.

"Great work Ultra Guardians, now let's head back too…" Lusaimne began turning around to see the guardians were exhausted. "Let's call it a day, the surprise can wait until tomorrow, all of you go home and get some rest."

"Wait, why don't you all stay at the mansion?" Ark offered.

"Really?" Lana asked.

"Sure, we have more than enough room, and that way Kiawe and Charizard can rest too." Ark said.

"It sounds like it could be fun, having everyone over, is that okay mother?" Lillie asked.

"I don't see any problem with it, as long as you kids make sure to get some sleep, and that you check with your parents first." Lusamine said. "Kiawe, I'm sure we have some clothes you can change into as well."

"Thank you very much!" The group said with a smile.
