Ling Ye, the top ghost-type Pokémon master, was drawn into a parallel world by a black hole in time and space when he challenged Ghost Dragon. Six of his friends (Gengar, Shield Swordsman, etc.) Were separated, and only Gengar was with him.
This is a world where Pokémon does not exist. The level of technology is similar to that of the protagonist's original world. However, various ghost stories are prevalent around the world. Ghosts are not fictions, but real spiritual creatures - most of them are condensed from human negative emotions (fear, sadness, resentment), or are born from the energy changes remaining in the turbulence of time and space. They also incorporate the characteristics of classic ghost stories from various countries, with different strengths and habits. Some are hidden in human society, and some occupy specific areas and pose a threat to humans. Ordinary people are helpless against ghosts. Only a few people can sense ghosts or master weak methods of exorcism.
Supplementary settings (mega evolution + bond power): Ling Ye carries the Gengar mega stone. Due to the energy disorder of time and space after time travel, the energy resonance required for mega evolution is blocked. Only when Gengar energy is full and Ling Ye is in a desperate situation, the incomplete mega form can be triggered briefly; the power of bond It is the deep spiritual connection between Ling Ye and Pokémon. As partners reunite and the bond deepens, it can be gradually unlocked. The highest level can achieve "energy symbiosis between people and Pokémon". Ling Ye can briefly borrow some of Pokémon's abilities, and Pokémon can also receive Ling Ye's spiritual blessing, and even unlock exclusive bonding skills.
