Pokemon: Eclipse Adventures

Starter and more info

After some randomizing, its been decided the starter will be Monferno from Island scan on Ula Ula island.
Edit: do to some contemplation, I've come upw it something else, but it will still involve Monferno to a degree.

This timeline is different to the games, but it has elements of them. Instead of being purely the games-verse, its after the Journeys anime, about a year after. During this time, Moon had moved to alola with her mother, and she met the regions professor. After a chance encounter with Tapu Koko, she was entrusted with a Z-ring by Kahuna Hala. She travels through Alola, meeting new people, many pokemon, and completing a number of trials. She meets a couple of the friends Ash made in Alola, including the Alola Class. On their travels to Galar to find her father, Lillie found a Cosmog. This Cosmog would grow up to be Luna. When Moon shows up onto the third Island, its around the time Faba decides he wants to 'redeem' himself by making artificial Ultra Wormholes to gather Ultra beasts to study instead of using a Cosmog. It works, and for a few weeks, ultra wormholes begin appearing, and Ultra Beasts show up. The Ultra Guardians mostly handle this, but when Moon visits Aether Paradise, a Ultra Wormhole appears and kidnaps Lusamine, and Guzma, doing some voluntary community service, jumps in after her. Moon, with Lillie and Gladion, go after them with a newly evolved Lunala. They beat Ultra Lusamine, who this time comes down with some illness from the neurotoxins that are not as easily handled as the first time. When the Alola league comes around, Moon has beaten all the grand trials, so she participates. She makes it all the way through, but when facing Ash, she's beaten. But this Tournament had a prize for the one who made it to Ash, the title of Co-Champion, due to Ash's traveling nature having him travel all over the world.

Moon's Rotomdex is not Ash's, its a second one Kukui made.
