Spartans

The Spartans were a group that fought alongside Samurai Jack in the show with the same name.

History
The Spartans are a society similar to the ancient Greek civilization of the same name. For years, they were attacked by a rogue, mechanical beast which had already claimed the surrounding kingdoms. 300 Spartan warriors were able to hold off the Beast's army by defending a small ravine that led to the city, making their vastly superior numbers meaningless. During the reign of Spartok, the fifth Spartan king to defend the ravine, Samurai Jack came across the Spartans after saving the King's son, Brotok, from the Beast's monsters. After gaining their trust, Jack informed Spartok of another passageway through the mountains that they could sneak through and attack the Beast's lair. Spartok, Jack, and 50 of the best Spartans went through the path. After fighting the robots defending the area, Jack and Spartok made their way inside to face the Beast in person. The Beast was slain when Jack through his sword into the mechanical monster's body. As the monster was about to explode, Jack picked up two shields and jumped in front the blast, seemingly sacrificing himself to save the king. The Beast's armies self-destructed soon after, and the war was over, but Jack was gone.

Years later, an old Spartok recalled the story of the "300 plus 1" who saved them all from the Beast. Although Jack was considered to have died in the battle, Spartok believed that the mysterious warrior who helped them that day had somehow survived.
