Ep. 125: The Darkness Returns — Part 1

125

The first duel of the semifinal begins. Marik makes it a Game of Darkness with "dark energy strings" that connect Marik and Jonouchi to each monster they summon. As a monster is destroyed or weakened, a corresponding amount of "damage" is dealt to the monster's owner. As it turns out, Jonouchi is the only one whose physical energy is visibly affected, albeit not as badly as Marik had expected. (Source: Yu-Gi-Oh! Wikia)
