The Reveal Glass was first hinted at in The Power of Dreams, where Hood Man realized that the Forces of Nature needed a special mirror to unlock their alternate forms.
Team Plasma managed to obtain the Reveal Glass sometime before Legendary Tornadus, where a group of Team Plasma Grunts used it on Tornadus from a distance while attempting to capture Giallo.
The Reveal Glass made its first proper appearance in Colress Machine, where it was shown to be in Colress's possession, using it to transform Thundurus and Landorus into their Therian Formes to fight Blake.
In PS547, Kelden accidentally broke the Reveal Glass while trying to strike down Colress, causing the Forces of Nature to revert to their Incarnate Formes and allowing the Swords of Justice to defeat them.
The Reveal Glass may be based on the Demon Detecting Mirror, an item in Chinese mythology that could reflect the true identity of a yaoguai.
