Defenders of the Earth S01E10 - The Hall of Wisdom

When the awesome intergalactic of storehouse of knowledge, the Hall of Wisdom, makes a once-in-a-lifetime visit to the galaxy, Ming raids it in order to gain possession of the Quasar Weapon, with which he can conquer the Earth. The Defenders battle through Ming's forces and reach the Hall first, but tragedy strikes when one of them is severely hurt. As a Defender's life hangs in the balance, the Hall of Wisdom is revealed to house a remedy, but the price itself may be too much for the heroes!
