A young girl who is a prodigy at Pokemon battling. She has a unique style of training her Pokemon that Ash is initially skeptical about but later learns from. She could be from a far - off region and has her own goals in the Pokemon world, like trying to find a legendary Pokemon that is said to be able to grant wishes.
There could be an old hermit who lives in a hidden forest. He has a deep connection with the forest Pokemon and can communicate with them without the need for Pokeballs. Ash stumbles upon his place during his journey and the hermit teaches him about the ancient ways of Pokemon and the importance of harmony between humans and Pokemon.
A young girl trainer who has a special ability to communicate with Psychic - type Pokemon on a deeper level than most. She could join Ash on his journey and teach him new things about Pokemon communication.
A new character could be a brilliant but shy Pokemon researcher named Lily. She could be constantly studying in the academy's library and Ash could approach her for help with understanding some complex Pokemon biology. Another could be a tough - looking but friendly trainer named Max who has a unique team of dark - type Pokemon. And there could also be a strict, no - nonsense teacher named Professor Oakley who challenges Ash's training methods.
Another possibility is a Torchic. Torchic is a fire - type, and it's small and cute but can grow into a very strong Combusken and then Blaziken.

It could be a young girl named Lily who has just started her Pokemon journey. She has a Pikachu - like Pokemon but doesn't know how to train it properly. Ash steps in and shows her the ropes, like how to train it to use electric attacks more effectively.
