Yu-Gi-Oh! GX - Episode 073

Source of Strength, known as '''Kenzan vs Saiou! Dinosaur DNA''' in the Japanese version, is the seventy-third episode of the Yu-Gi-Oh! GX anime.

Summary
Sartorius sits at his headquarters, making further predictions with his tarot cards. He determines that though both Jaden Yuki and Aster Phoenix are influencing his destiny, there is a third person. He journeys to Duel Academy once more to determine who that person might be. He realizes that the person he seeks is Tyranno Hassleberry, who himself realizes that Sartorius is the one that Chazz Princeton has been raving about in regards to The Society of Light.

Sartorius challenges Hassleberry to a duel, while promising to set Chazz back to normal should Hassleberry win. However, Sartorius has never used a Duel Disk before, so Hassleberry much explain to him how it works. The duel goes quite evenly, with both players being reduced to only a few hundred Life Points in a few turns. Sartorius wins by using "Reversal of Fate" to change the effects of his "Arcana Force" monsters. Despite his loss, Hassleberry is not converted to the Society of Light, much to Sartorius' shock. Hassleberry explains that in the past, he had excavated some Dinosaur fossils. His leg had been injured, and so the bone had been replaced by the fossilized Dinosaur bone he had uncovered. He claims that this "Dinosaur DNA" is what grants him immunity to the powers of Sartorius. A few days later, its revealed that Sartorius has officially enrolled at Duel Academy as a student.
