Metroid II: Return of Samus is the sequel to Metroid and the second game in the Metroid series and only one to appear on the Game Boy. It is about Samus Aran's mission to exterminate the Metroids on their home planet, SR388. Although it is the second release in the series, chronologically it takes place after Metroid Prime 3: Corruption and before Super Metroid. Metroid II first introduced the Metroid life cycle, where they grow from an infant to an adult, and then to their Alpha, Gamma, Zeta, and Omega forms. Samus kills all Metroid forms on the planet and defeats the queen of the Metroids on the planet, the Metroid Queen. However, due to the Metroids exterminated on the planet, the X Parasite is able to multiply without the Metroids stopping them. The X eventually take over the entire planet and threaten the entire galaxy in Metroid Fusion.
