Rainy Turtloid is one of the eight bosses of the Megaman X6. Rainy Turtloid was created by Gate as a member of water element research. He also received elevated defense that allowed him to explore highly polluted areas considered totally dangerous too much for humans and Repliforce. But however, his defenses were considered very dangerous and the other researchers demanded that he be weakened, which Gate did not agree and if the opposed this fact. Not wanting to see his master get punished, he then committed suicide, Gate then resurrect Rainy Turtloid to become one of Nightmare Investigators, sending him to the Inami Temple.
Later in the stage of the boss known as Rainy Turtloid, when X or Zero fight against Rainy Turtloid he is a very defensive boss because he can only suffer damage if his critals are destroyed and also they regenerates after of a time. He'll shoot missiles and then hide in his shell, and then drawing blades into his shell and spinning around the whole arena. And then when he has half of his life he will spin faster and he will also use a meteor shower, which will make it very difficult to dodge his attacks. His weakness is the weapon of Blizzard Wolfgang that is called Ice Burst.
