Soul

The daughter of Gem and Noir, Soul was born 24 BD along with her twin sister Heart. She was the primary focus of the Prophecy of Generation I, tasked with the job of protecting The Guardians. After failing to maintain balance in the world, Soul sacraficed herself, along with her friends to allow the gateway to The Spirit Realm to level with their own.

Life
Soul is one of the characters that reoccurs through the Generations due to her being granted Angel status by Arceus upon her death.

Generation I
Attacked by a Pokémon at the age of seven, Soul developed a phobia of all Pokémon, meaning that she did not leave on her Jorney when her sister did. Unknown to her at the time she was part of an intended prophecy that fortold that if the siblings set out one would bring about damnation while the other would save it. The Wise woman who gave the Prophecy assumed Soul would bring damnation, and when Soul learned of this she became determined to prove the Prophecy wrong.

See Generation I for the full story.

After releasing the souls into The Spirit Realm, Soul went on to found The Elite Four with her friends, who had also been part of the Prophecy, marrying Richie and having a son, Nikki. In the end she sacrafice her own life to rebalance the world, and her own soul to have her sister.

Generation VII
She is next mentioned during Generation VII around the time Ryu was born. It is hinted that she is the one that provided Platinum and Pearl with information on Alibia.

Generation VIII
In Generation VIII she appears only briefly to speak with Looker who is revealed to be an angel himself. She also senses when Gem and later Noir are released from The Abyss.
