The Mirror Marionette emerged from Dax Shardbinder's earliest experiments with reflected glyphs at the Fracture's epicenter. When Dax manipulated a particularly unstable mirrored glyph during the Chaos Twin event, the reflection gained sentience and began independently replicating his manipulation techniques, becoming a permanent entity that now serves the Brotherhood's chaotic agenda.

The Mirror Marionette exists as a semi-corporeal entity composed of layered reflective surfaces that can capture and duplicate disc trajectories. It manipulates spatial perception through precise light refraction, creating temporary mirrored pathways that alter disc flight patterns. The entity feeds on perceptual confusion, growing stronger when opponents doubt their own throws, and can simultaneously maintain multiple reflected illusions across different parts of the course.

The Mirror Marionette serves as the Brotherhood's primary instrument of throw manipulation, creating reflected duplicates of successful shots that either assist allied players or redirect opponents' discs into hazardous terrain.
