Legendisc

The Legendisc is an item from the Aligned continuity family.

The Five Legendiscs (レジェンディスク Rejendisuku) are "secret items" capable of sealing away fearsome beasts. Such is their power that Predaking was sealed away by Optimus Prime's Autobots using the Legendiscs.

Two factions in the Sengoku period both had Legendiscs of their own, which they used as part of military standards.

Another Legendisc fell into the possession of the Japanese Tatewaki family, who regarded it as a "sacred mirror". One day, while Isami and Sekishūsai Tatewaki paid their respects to the sacred mirror, the Predacons Budora and Gaidora, who were tracking the Legendiscs, came across the sacred mirror and attempted to steal it. Isami attempted to flee with the sacred mirror on Sekishūsai's orders, causing the two Predacons to chase the boy. Realizing that the two demonic robots would cause destruction to Tokyo in search of the Legendisc, Isami tried to make a stand, but the Predacons simply threatened the lives of nearby bystanders. The Legendisc responded to Isami desperation, summoning the Swordbot Samurai Team through Isami. When the Swordbots defeated the Predacons and their Jaki minions, the Swordbots and Isami were transported back in time to the Battle of Sekigahara, where they saw the opposing armies each have a Legendisc of their own.
