Theorysonic XPower

 was a LaserDisc-based full motion video (FMV) console and home multimedia entertainment that was developed and manufactured by the El Kadsreian company, Theorysonic. It was launched on October 12, 1994, serving as a direct response to the console. The XPower incorporated technology from Theorysonic Codear and Theorysonic 3DO, resulting in a unique gaming experience. The XPower, unlike LaserActive, uses Theorysonic's proprietary XLD format.

The XPower represented a convergence of technologies, combining the capabilities of LaserDisc, Theorysonic Codear, and Theorysonic 3DO, making compatible with the aforementioned consoles. This amalgamation allowed for an unprecedented level of FMV-based gameplay, elevating the gaming experience for users while also overlaying the LaserDisc video with other types of gameplay. Notable titles included "Galactic Odyssey", an expansive space adventure, "Mystic Quest", a fantasy RPG, and "Road Racer", a racing game, all combining the FMV scenes with sprite- and tile-based gameplay.
