Transformers: Shattered Glass is a Transformers alternate-universe storyline and brand used across comics, toys, and related media. It reimagines familiar Autobots and Decepticons with reversed moral roles, most notably portraying heroic-looking versions as villains and vice versa. The concept began as a convention-exclusive comic and later expanded into other official releases. It is not a single anime series, but a recurring Transformers sub-franchise centered on this mirror-universe premise.
