Basculegion

Basculegion, known as Idaitou in Japanese, is a dual-type Water/Ghost Pokémon introduced in Pokémon Legends: Arceus. It evolves from White-Striped Basculin when it levels up after losing at least 294 HP from recoil damage without fainting. Basculegion is a large, fish-like Pokémon with green skin and a black streak along its back. Male Basculegion have red smoke-like features around their body, while females have pale blue ones. These smoky features are actually the souls of Basculin that perished during their attempt to swim upstream. These souls grant Basculegion immense power, allowing it to swim effortlessly through strong currents. In the Unova and Kitakami regions, it is considered to have originated from ancient times. Male Basculegion are known for their powerful jumps, while female Basculegion can conjure and control terrifying illusions. Basculegion is said to be unrivaled in the rivers of the Hisui region. It also appears in other Pokémon games, with its unique abilities and attributes.
