Mirror Darkness is a stage in Tekken 2. The fight takes place in a large, dark room with a bare grey floor. In the background, there are many mirrors that can be seen reflecting the fight taking place, hence the name "Mirror Darkness".
- This is Devil and Angel's stage.
- The stage theme is called "Be in the Mirror", whose melody is the same as "Emotionless Passion", the theme of Kazuya's stage, Eternal Darkness.
- The Arcade soundtrack does not feature a unique theme for this stage: the theme for Kazuya's stage is used instead.
- Although the onscreen display is not reflected in the mirror, the words that appear at the end of a round (KO, You Win etc.) are reflected.
- When playing in Practice Mode, the button inputs which are displayed onscreen will also be reflected in the mirrors.
