Crystal Snail

Crystal Snail, known in Japan as Crystar Mymine (クリスター・マイマイン), is a snail-type Maverick in Mega Man X2. His origins and motives are a mystery; regardless he guards the Energen Crystal mine under Sigma's command.

Strategy
Besides using Crystal Hunter, he also uses his shell to his advantage. His weakness is Magnet Mine, which knocks him out of his shell. Once he is out of his shell, the player can dash at it to knock it away. Snail will try and follow it; the player can essentially play keep away with him for the entirety of the battle. If Snail and his shell collide with each other, he will receive double damage.

A unique trick can be utilized in this battle: place a Magnet Mine on the wall behind X, and then shoot another mine at Crystal Snail — not only will it knock him out of his shell, but he'll fly right into the other mine.
