Ninjask

Ninjask, known as Tekkanin in Japanese, is a dual-type Bug/Flying Pokémon introduced in Generation III. It evolves from Nincada starting at level 20. Notably, if a player has an empty slot in their party and an extra regular Poké Ball when Nincada evolves, they will also obtain a Shedinja. Ninjask resembles a cicada with a mostly black body, yellow head, and red eyes. It is renowned for its incredible speed, said to be so fast that it is nearly invisible to the naked eye, and its loud cries can cause headaches if listened to for too long. Ninjask has made appearances in the anime, and has been used by several trainers. Training a Ninjask requires skill, as it tends to disobey trainers it deems unworthy, testing their abilities with its persistent loud cries.
