Pokémon Nanja: Ninja Adventures in the World of Pokémon

 "Pokémon Nanja" or something similar. However, there is no official game by this exact title in the Pokémon franchise. It might be a fan-made or an unofficial game that incorporates elements of both Pokémon and ninja themes.

In a possible "Pokémon Nanja" game, the player could control a Pokémon trainer who also has ninja abilities, such as stealth, agility, and quick combat skills. The game might blend traditional Pokémon gameplay, like capturing, training, and battling Pokémon, with ninja-inspired challenges. These could include sneaking through enemy bases, using Pokémon to solve puzzles or defend against attacks, and fighting opponents in fast-paced, ninja-style combat.

The setting might involve hidden villages, mysterious forests, or ancient temples where the player must use both their ninja abilities and Pokémon companions to complete missions. The game could also introduce ninja-inspired Pokémon with unique skills that add a new twist to the traditional gameplay. Players might have to outsmart opponents not just with their Pokémon, but also with their own ninja skills, making it a unique and exciting experience.
