Death (Main body)
Death, Valerie, Leaf, Serena and Esdeath had explored a fair bit, with Death bringing them to the Safari Zone, where he befriended and captured a Dragonair and Dratini (These two went with his Avatar that remained in Kalos), as well as swinging by the Eevee brothers place since Valerie's Eevee had finally evolved into a Sylveon.
The reason he wanted to visit them before Ash could get there was because of little Mikey, who didn't want to evolve his Eevee into Vaporeon, Jolteon or Flareon. After telling them about Umbreon, Espeon, and Sylveon, Mikey wanted to have his Eevee evolve into a Sylveon, so they stayed a few days to train Mikey's Eevee to use Charm and Baby-Doll Eyes, and then told Mikey to continue having his Eevee practice those moves and try to master them while just focusing on having fun and being a good friend to his Eevee.
They did not tell Mikey about Fairy Type, but rather just told him that Sylveon was likely the most powerful known Eeveelution, while still being very adorable. After that, they teleported to Professor Sycamore's laboratory and spent a day there while he excitedly studied Valerie's Sylveon and verified that it was a Fairy type.
Death, naturally, traded places with his Kalos Avatar and spent this day with Diantha, and even brought her to Sycamore's laboratory secretly to meet Sylveon after their date for the day. It proved to be a fun time.
Finally, though, the group went to Cinnabar Island where he delivered his Jaw fossil to the fossil restorer and received a Tyrunt, which he sent to his Avatar in Kalos. Rather then battling the Cinnabar Gym right away, Death decided to bring his female companions to Seafoam Island and to train with them there for a while, since by that time one of his avatars was training Ash, Misty and Brock, and their Pokémon, in his Ranch dimension, and he did not feel like revealing that he could be in multiple places at once just yet.

Death's Avatar following Ash, Misty and Brock secretly
When Death started following Ash, Misty and Brock with one of his avatars while they went to Lavender Town, he initially started with bringing Queenie, Arbok and Weezing with him. Arbok and Weezing originally belonged to Jessie and James, but after training them for so long and taking such good care of them, they were now loyal to him, and had grown a lot.
Additionally, when Ash met the three ghost Pokémon, he actually managed to catch it this time, and he departed towards Saffron again. Death, then, created a new Avatar to secretly follow Ash and crew while he confronted and caught the a gengar, then he went to check on Cubone and Marowak.
Due to how severely he had crippled Team Rocket in Kanto, they hadn't killed Marowak yet, so he was able to catch both of them and then race to catch up with Ash, Misty and Brock and dispelled the temporary avatar that had no Pokéballs.
Ash and gang surprisingly did not get lost on the way too or from Lavender Town, so they made great time. Death got ahead of them and met them as they approached the gym. He noticed Misty immediately blushing the moment she recognized him "A haunter...Not bad" Death commented.
"How'd you know?" Ash asked with surprise.
"Pi-pika." Pikachu answered as well.
"Sabrina's Kadabra has now evolved into an Alakazam, so beating her even with Haunter will be tricky." Death insisted "So I am going to put you and your Pokémon through some training. Do you object, Ash?"
Death casually glanced at Pikachu to scan him since he hadn't done so in a while.

Ash seemed to look at Misty and Brock as he considered the offer.
"A week is all I ask. Your Pokémon will have to work hard but they will get much stronger, and I've selected 6 more moves to teach to your Pikachu since it mastered the two from before. I extend this offer to your Pokémon as well." he said. directing the last part to Brock and Misty.
Ash nodded to Death "I guess we can't turn down an offer like that. You seem to know a lot."
Death nodded and smiled "Good. Now, the place where I'm taking you, the Pokémon living there are off limits, it is a sanctuary. You'll find many rare and friendly Pokémon there, though."
Ash nodded "I understand." he agreed.
Death approached and opened a gate near them "Lets go through this." he said before walking through.
The trio followed Death through the Gate and arrived at his ranch dimension near one of the two cottages as a familiar little girl with red-tinted hair in a white hooded cloak came out of it excitedly and hugged Death.
"Good afternoon Summer." Death returned the girls hug and saw Remnant Prime's Ruby and Yang come out of the cottage as well.
Brock, upon spotting the two women, started moving towards them excitedly, but stopped when Crescent Rose was unfurled by Ruby instinctively.
"Careful Brock, these two lovely ladies are warriors, they wont be swayed by your attempts at flirting with them." Death warned him.
"Oh, you brought guys here with you. This is a change." Prime Yang chuckled.
"I brought them to train them and their Pokémon." Death explained to Yang "They'll be here for the next week."
"Well, we will see them a few more times then." Ruby noted "Mom, lets go inside and not bother them." she said to Summer.
Summer reluctantly let go of Death "Okay!" Summer answered as Death released her and then grabbed Ruby and Yang by their hands and guided them into the cottage again.
"Did she call that little girl mom?" Misty asked with surprise.
"Yeah, Summer is her mother." Death verified "It's complicated. Try not to worry about it." he looked at Ash and Pikachu "Pikachu, please enter your Pokéball for a bit so I can give the Pokémon moves to you like last time."
The moves that were given to Pikachu using TM's were Draining Kiss, Swift, Detect, Grass Knot, Light Screen and Dig, and Death spent the next week pushing all of their Pokémon hard, and while Pikachu had made a lot of progress, he hadn't mastered any of them yet, but at least he made a lot of progress.

When Ash's training was completed, his Haunter had evolved into a Gengar and Death's avatar brought Ash, Misty and Brock back to the entrance of the Saffron City Gym before 'disappearing' and secretly following them again as they entered the gym and went back to challenge Sabrina.
Then they entered the arena area, the trio was surprised to see Death already there, seated on Sabrina's large throne with Sabrina seated beside him, snuggling. The chair was large enough for the both of them, and having Death beside her made Sabrina seem very happy.
"What's that Pokémon?" Ash asked with surprise. There was indeed a Pokémon laying down in a little bed next to Sabrina's throne, and it was none other then Death's Umbreon, which was a bit lighter then yupical Umbreons, and blue markings instead of yellow (Shiny).
"This, Ash, is an Umbreon, an evolved form of Eevee that is Dark-type" Death explained to Ash "Serena's Eevee evolved into a Psychic-type Espeon and Valerie's Eevee evolved into a Sylveon. While Espeon and Umbreon have been seen before, their evolution methods were only recently discerned by myself, and Sylveon is a completely new and previously undiscovered species. This information will likely start to be made public in the next year or so."
"What type is Sykveon?" Misty asked.
"Fairy type, like the move draining kiss, that I taught to Pikachu." Death answered "Sylveon's existence should be the final proof needed to get the regions to accept the existence of Fairy-type Pokémon.
"So Eevee can evolve into six different forms?" Brock asked with surprise.
"Eight" Death corrected Brock "The method of evolving Eevee into the grass-type Leafeon and into the Ice-type Glaceon just haven't been determined yet. And like Sylveon, there might be other evolutions that haven't been discovered yet. Eevee is quite the fascinating Pokémon" he looked again at Ash "You're not here to admire Umbreon, though. You want to battle Sabrina again."
Sabrina chose this moment to kiss Death's cheek before getting up "Very well. Lets see what you have this time." she took out a Pokéball from her belt "Alakazam"
Sabrina had reached her end of the arena and called out her Alakazam "Death has been a huge help in training up all of my Pokémon, but since this is a rematch I'll just use my Alakazam." she announced "The battle will be one on one, until one side concedes or can no longer battle."
Death was up as well, getting into position across from the referee for this rematch between Ash and Serena, and soon the battle started, with Ash, as expected, using Gengar. It had been going on for a minute or so when a beautiful woman he estimated to be around 25 to 27 years old with breasts similar is size to Sabrina's, came up beside him. She had long red hair in a ponytail and wore a form-fitting suit with a knee-length skirt, and had amber eyes that seemed to pierce into his soul.
"Good day, Miss Lorelei. I wasn't expecting to see one of the Elite Four here today" Death greeted her.
"So you recognize me?" Lorelei was a bit surprised by that, he guessed it was due to his origin. He deduced that she had looked into him.
"I've studied up on all of the important trainers in Kanto." Death insisted nonchalantly "So what brings you here? And why now? I don't believe it's a random visit."
"Indeed. You have been staying here a while, and yet we keep getting notifications of you beating other gym leaders." Lorelei acknowledged "It's like you can be in two places at once."
"Fifty-one." Death corrected Lorelei "Just like Sabrina, I have my own abilities. I can create as many as 50 avatars and simultaneously experience everything that they do. Of course, just because I CAN make that many avatars doesn't mean I'd want too. Mostly I try to keep it under ten when possible."
Lorelei was shocked by Death's declaration.
"I don't mind letting you know, Miss Lorelei, but it would be for the best that it is kept a secret. I don't want bad elements such as Team Rocket and similar organizations targeting my friends and I." Death explained to her.
Something seemed to click in Lorelei's mind "You're the one harassing Team Rocket?" she guessed.
"Bingo" Death chuckled "And no, I'm not killing anyone. I just transported the captured Team Rocket members to a hidden prison. I'd have turned them over to the league, but if I did their boss would stage a mass-breakout. So I'll release them to the Kanto and Johto Pokémon leagues once I am satisfied that they lack the means of breaking out easily."
"Where are these prisoners? A lot of people have gone missing lately, how could you possibly hold them all?" Lorelei asked, seeming stumped by that detail.
"I have my own hidden city called Lyonesse. I can show it to you if you want, to verify that the prisoners are being treated humanely." Death offered to her. "We can discuss it further once the challenger leaves. For now, though, I find myself seriously questioning the wisdom of Kanto's Pokémon League."
"Oh, do tell." Lorelei was wondering what he wanted to complain about.
"Naming Sabrina a gym leader. I get that she is the most gifted Psychic in the world today and it gives a certain amount of prestige towards Kanto just having her as a gym leader, but mentally she's been a mess." Death admitted "She's doing better now that I am here, but she was acting rather awfully before I stepped in to guide her and the League was ignoring it. If I ever leave, who knows whether or not she'd revert to her previous self. Probably not in short order, but eventually perhaps."
"You seem to care about Sabrina" Lorelei acknowledged "Well, while I've not heard of any problems with Sabrina, I will investigate this matter."
Death nodded and looked at the battle, which Ash had just won "I'll meet you outside the gym in a bit, Miss Lorelei, and bring you to Lyonesse." after saying that, he walked over to join Sabrina as she was passing a badge to him and congratulating him for his victory.

just a heads up, chapters may be slowed down a bit due to playing through Shining Pearl, but will still be working on chapers even if it is only one on Saturday evening/sunday morning for the next few weeks. Hopefully only one more week at that pace but two at most, then I should hopefully be back to 2-3 chapters per week
