Synopsis by Hal Erickson
The mysterious young stranger engages the newly arrived Goku in combat, but only to test his opponent's strength. Once satisfied, the stranger reveals his true identity (hint: this is the fifth episode of DragonBall Z's "Trunks Saga.") Also revealed is what the future has in store for the Z-Warriors. First telecast in Japan on January 8, 1992, the pivotal episode "Mystery Revealed" made its American debut via home video in 2000.
