(At this time Ash only has 2 badges from Mylene and Gardenia, since Roark had something to do and couldn't accept Ash's second Challange)
Ash was standing at Lake Valor the day before the start of the Wallace cup and was wondering if he should reveal the truth.
You see Ash isn't the dense idiot that pretends to be weak because he wanted a challenge since he had every Pokémon in the Kanto, Jotho, Hoenn, Sinnoh, Unova, Kalos, Alola, Galar, Torren and Tandor since Reborn and Ore don't have their own Pokémon.
Ash also was the son of the Kantonian champion Aurora and the Reborn champion Adam.
His father was also Arceus who was found badly injured by Aurora and then fell in love with him. At their marriage Adam gave Aurora the body of an Arceus.
Adam and Aurora got together got 11 Children in order of being born Dia (Dialga), Palmo (Palkia), Gina (Giratina), Jo (Crimson-Shadow Lugia) Ash (Arceus with all plates), Incey (Arceus with all plates), Minami (Arceus with all plates), Golly (Arceus with all plates), Mark (Arceus with all plates) and Trenor (Arceus with all plates), Golly (Arceus with all plates).
The other family members were as family parings:
Giovanni and Sabrina with their children being Silver (Ghost-type Arceus) Johto Elite four, Ariel (Dark-type Arceus) a coordinator and upcoming Dark type master, Leaf who was adopted by Giovanni after her parents died (Grass-Type Arceus), Amelia (Poison-type Arceus), Surch (Bug-type Arceus)
Wallace and Kahili with their children being Reshow (Dragon type Arceus) Reisa (Water-type Arceus) a coordinator and upcoming Water type master, East (flying type Arceus),
Tobias and Cynthia, their children are Alain Pokémon trainer and researcher, Aria Kalos queen (fairy-type Arceus), Verity world seer, Nora (ground type Arceus) Ranger,
Steven and Wiona with their children being Lisia a star, Radium (Rock-type Arceus), Aera a flying master
Wulfric and Valerie whose children are Eve who is a fashion designer, Alice (Ice type Arceus )an Ice type specialist and a coordinator, Flora a flower lover and Pina a professor.
next Lucian and Olympia whose children are Anabel (psychic type Arceus) 2nd in command to Ash in the international police, Daniel who likes to read in the stars and Yuni who likes to spook others,
third to last Ghtesis and Thrister with their children being N Pokémon trainer, Nate (Normal type Arceus) Pokémon trainer, Rosa Pokémon trainer and Jullie professor, Flomer (Fire type arceus) a great cook,
second to last are Diantha and Seibold whose children are Elline (Electric type Arceus) an electric type of trainer, Konomi a Mashal artist (fighting type), David an inventor (Steel-type Arceus), Oscar a great singer,
Lastly whose parents sadly have already passed away queen Ilene from Cameron palace, Ridley an Aura guardian and Korrina an up-oncoming gym leader.
Then there are also Ash's grandparents, Palermo and Gurkinn.
The reason why Ash had all Pokémon was a war between Tandor which had an alliance with Torren attacked Ore and Reborn in the war Ash caught all Pokémon while conquering Torren and Tandor and freeing them from their Dictator.
Although he had every Pokémon before his journey, he only trained 300 of them.
While he was thinking about his decision his mother and Wallace walked up to him and told him that it was his decision, and they would be always by her side with the reassurance Ash decided to stop holding back and tell Dawn and Brock about this after the tournament.
After he made the decision Aurora gave him the 597 Pokémon since 2 were with his Girlfriend Lillie Aether and one was sitting on his shoulder hiding her true self.
After the meeting with his mother and his uncle he to the Pokémon center to call Pr. Oak where he told the professor that he is now stopping to hold back and asked him to send Ash all his Pokémon, who did that and told Ash that Squirtle, Lapras, Primape, Pidgeot, Haunter and Butterfree are back to which ash smiled having missed the six.
After that Ash ended the call and then went to his room and took out a packet that arrived yesterday from his cousin Queen Ilene, which was his Aura guardian outfit, he wore on the festival half a year ago and laid it onto the Table before going to bed.
(Next Day)
"Today is the beginning of second most important Contest of the season the Wallace cup and we have 2 special guests one is the person whose name is this cup the Hoenn Champion Wallace Auran and our second special guest is his sister the Kanto Champion Aurora Auran (Ketchum was a name to use their true name), Next, we have Mr. Sukizo, Mr. Contesta and lastly our own Nurse Jo and I'm Marian, and I will be your commentator," Marian said as she and the other 5 appeared while the crowd roared from applause at them appearing.
Meanwhile in the waiting room, Dawn, May and Zoey were waiting for the contestants to be announced and waiting for Ash to arrive since it had been three minutes since he went to the bathroom. When he came back, they were shocked to see him in his aura guardian outfit but in the background Lillie (his Girlfriend), Ariel, Reisa and Verity were smiling at seeing him in that outfit.
In the next 3 hours everyone went to the stage performance Reisa using her Feraligatr, Lillie her Dewgong, Verity using her Empoleon, Ariel her Sharpedo, Dawn her Bunneary, May her Warturtle and Zoey her Finneon. All the while Ash hasn't been called.
"Ash Ketchum get ready" a Security guard said as Ash nodded and grabbed the zeptar before leaving the Room with the others wishing him good luck.
(Meanwhile in one part of the stands)
Brock was sitting with 'Pikachu' in the stands alone when he suddenly heard "Brock". When he looked over, he saw Max, Drew, Solidad, Norman, Caroline and Johanna walking towards him.
"What are you guys doing here" Brock asked confused.
"Well, we were invited by Aurora and Wallace and Drew and Solidad missed the cutoff time for the entrees" Johanna said, "but where is Ash".
"Ash is the last one to do a stage performance the rest have already done their" Brock said as the others sat down.
"Since when is Ash doing Contests" Drew asked confused since he only heard of Ash lying with May in the last contest in Kanto last year, but else Ash never had entered a contest to his knowledge.
"Well after seeing May again a week ago, he decided to also participate" Brock said as the others were now interested.
(In another part of the stands)
Ash's ten Siblings were sitting next to each other discussing about what they saw until now.
"Reisa, Ariel, Lillie and Verity did a great performance who do think Ash will use" Minami asked.
"Who knows Ash has over 300 Pokémon, it isn't predictable what Pokémon Ash will us, but I think it will be a water type" Palmo said as the others nodded.
(Back to the battlefield)
"Now to our last contestant we have someone that mostly does normal battles Ash Ketchum" Marian said as Ash appeared on the field with his Aura guardian outfit and his zeptar in his hand.
"Electruxo, show them your beauty" Ash said as the Water Starter from Tandor appeared in front of Ash.
"Thats a rare Pokémon an Electruxo a Water/Electric type from the Tandor Region" Marian said as the crowd roared at the appearance of the rare Pokémon.
"Let's start off with Discharge on the water" Electruxo charged electric waves on the water which electrified it "Now use Whirlpool and raise it into the Air" with that Electruxo turned all of the electrified water into a gigantic whirlpool and raised it into the air" Now Ice beam on it" Electruxo froze the hole Whirlpool and the frozen whirlpool then fell back to the ground and landed on the tip" water pulse and Shockwave on it" using that a both turned into ring rotating around the Whirlpool "finish it off iron tail" Electruxo used Iron tail on the side of the whirlpool turning it into a spinning ice Beyblade.
"Wow Ash used the Pool to turn it into a spinning frozen Whirlpool with a ring of Water and Electricity around it" Marian said amazed by the tactic of Ash.
"a beautiful way to show the combination of Water, Electricity and ice" Aurora said as the other nodded at the comment while the crowd roared.
Ash waved towards the crowd and left the stage with Electruxo by his side as he patted him on the head" great job out there my friend".
"No problem, Ash" Electruxo said.
When he entered the waiting room and went over to Dawn, May and Zoey.
"What Pokémon is that" Dawn asked as she and the other two looked at Electruxo in amazement.
"He is the Water starter of the third most difficult region of the world" Ash said as he ran his hand along Electruxo's back.
"But where did you get it" May asked confused about it.
"I will tell you that, meet me at the lake in an hour I still have to meet someone also get Brock" Ash said as the others nodded as he told he left the room and told Electruxo to wait for Ariel, Lillie, Reisa and Verity to tell them to meet him at the lake in an hour as well to which Electruxo nodded as Ash went to were his siblings sat.
When they saw him, he was tackled down by his four sisters while his brothers smiled when they saw him for the first time in 5 years. After his sisters let him stand up, he hugged each of his brothers after which he punched Dia and Palmo in the gut.
"What was that for" Mark asked his brother as he and the others were confused.
"For the chaos their copies caused back in Alamos (funnily I always thought it was Alomos town) town, and nearly destroying the time/space continuum and that was nothing, I could have also used Fairy, Dragon, Nuclear or Shadow type Judgement but I don't want to raise suspicion" Ash said.
"We got already our punishment from dad for this" Palmo said.
"And what would that be a slap on the wrist while he says that was idiotic" Ash said as the others snickered knowing how many times the two got away with that.
"No, they are forbidden to use their powers for ten years" Aurora said while she, Wallace and Electruxo walked up to them.
"Dad does know that I will challenge them" Ash asked.
"That is the only time we can use our powers" Dia said while Palmo nodded.
"Anyway, that was a great performance out there" Minami said as she bends down and scratched Electruxo under his snout.
"Thanks guys but I couldn't have done it without Electruxo" Ash said.
"Thats true a trainer is nothing without their Pokémon" Aurora said.
Ash returned Electruxo after Minami stopped scratching him to his pokeball, after which they left Stadium and went to the lake were they already saw Reisa, Lillie, Verity and Ariel waiting for them and Nucleon and Shadeon standing on each side of Lillie after greeting each other and Lillie giving Ash the pokeballs of Nucleon and Shadeon they waited for the others, while they were waiting they were talking to each other about what had happened in the last five years since they last met.
When the others arrived everyone apart from Johanna was shocked when they heard that Ash was part of the Richest and most influential family in the world who had 7 of the 12 champions in their family and a lot of Gym leaders and that he had been holding back all the time, of which they were at first angry why he did that but after hearing that he didn't want to have an advantage over others with Pokémon that had already had to fight in a war were that lasted for three years against 2 other regions and a group of cultists and an evil team that raised up in their region and their allies region they understood why he did what he did.
"Oh, and one last thing, you can stop hiding your true self Pikachu" Ash said as the ones that didn't know about it were confused as 'Pikachu' who was still on Brock's shoulder was engulfed in white light and when it died down there was now a blue Mew in Pikachu's place which surprised the ones that didn't know about it" is that really that surprising, remember what Pokémon she has already defeated or almost defeated, do you really think that a Pikachu could achieve that".
"true" they answered as apart from Drew and Solidad remembered what kind of Pokémon she already had defeated.
"And she achieved this while still holding back" Aurora said as Ash returned Mew to her pokeball" but I do have 2 Pokémon that hate to be in their pokeballs" Ash said while looking down at the two eeveelutions.
With that they went to bed with Nucleon and Shadeon sleeping on Ash's Chest.
