It seems like you're referring to the credits of Pokémon: The Johto Journeys, possibly in connection with PelleK, a Norwegian singer and YouTuber known for his covers and original songs, often in the power metal genre. However, PelleK is not officially associated with the Pokémon anime or its soundtrack.
The credits for Pokémon: The Johto Journeys (Season 3 of the English dub) feature the original theme song "Pokémon Johto" performed by John Loeffler. If you're thinking of a fan-made cover or remix by PelleK, it might be something he created independently and shared on his YouTube channel or other platforms.
If you have a specific question or need more details, feel free to clarify!
