A bonus teaser at the end of Kingdom Hearts II and expanded version in Kingdom Hearts II Final Mix features three unique characters in armor who hold Keyblades. Their names have been revealed to be Terra (テラ, Tera?), Ventus (ヴェントゥス, Ventusu?) (referred to as Ven (ヴェン?) by his friends), and Aqua (アクア, Akua?), which represent "earth", "wind", and "water"; similar to how Riku, Sora, and Kairi's names can be seen as "land", "sky", and "sea". The three characters were in armor primarily to hide their faces until the character designs were completed. Nomura chose armor because he felt he could not use the dark hoods already used in the bonus trailer of the first Kingdom Hearts game. Nomura has stated the characters are related to one or more characters already introduced in the Kingdom Hearts series.
