Henshin

Henshin (変身) is the Japanese word for "transformation," literally meaning, "to change or transform the body." This word is primarily used in manga, anime, and tokusatsu dramas for when a character transforms into a superhero. Henshin heroes (変身ヒーロー) usually have a "henshin call", a catchphrase which they recite when they transform. The word "henshin" is most often used by characters in the Kamen Rider Series, whereas other programs use various words such as souchaku (装着), or will use phrases unique to the story. Cutey Honey originated nude transformations in magical girl Eiyuu Senshi and Senshi Kyoudai programs. Video game character Viewtiful Joe also uses the word to transform himself.
