Saga



Saga (サガ) is the main antagonist of the Fifth movie.

Saga is a childhood friend of Zoro's (both went to the same dojo together).

He falls under the evil influence of the Seven Stars Sword when he uses it out of desperation to save his friend and possible love-interest, Maya, from pirates. The sword posses Saga to try to rise to full power and bring darkness to the world as well a possessing an entire Marine dojo to help in its quest.

Saga summons Zoro to at first stop Maya from using the sacred jewels to seal the sword's power then plans to use Zoro as a live sacrifice to increase its strength. Luffy manages to stop Saga in the climax of the film with the help of Maya's barrier. But the sword fuses with Saga's body, making him nearly unstoppable. At least until Zoro arrives and finally manages to free Saga of the sword's power with one sword strike. Saga survives though and resolves to continue looking for the sword of justice, his dream, to make up for his actions.

Trivia

 * Both Saga and Shanks lost an arm to save a friend at sea, Zoro and Luffy respectively. And both are still proficient swordsmen despite their handicap. Only instead of dismemberment, Saga's was merely disabled. He regained use of it when the sword took over his body. It is unknown if he can still use his arm after the curse was lifted.
