POWER RANGERS NINJA STORM
When the Rangers lost their powers, Cam used the Scroll of Time to travel into the past and retrieve the Samurai Amulet, a family heirloom in the possession of his mother. Cam travelled back to present day and used the amulet to become the Green Samurai Ranger, armed with the Samurai Star. A lost scroll would later reveal to Cam the Lightning Riff Blaster, which could summon the Mighty Mammoth Zord.
Lothor attempted to open the Abyss of Evil and release its evil into the world. In a final battle, he stole all of the Rangers' powers, but was defeated by their ninja skills and thrown into abyss. The powerless Rangers resumed their normals lives, free from the menace of Lothor and his army.
