Adult and Child Modes

Adult Mode and Child Mode (as named in a translated Japanese interview in Nintendo Dream) are game settings exclusive to the Japanese version of Metroid Fusion. These settings enable or disable kanji in the game to make it easier for players, particularly young children, to read text and follow the story. Additionally, the use of Child Mode affects the endings. Also exclusive to the Japanese version of Fusion, the endings depict images of Samus Aran in her past and present, rather than those of her in her Justin Bailey. Clearing Adult Mode shows those endings, which are present in localized versions of the game.
