|The Lava Monster|
|Species||Human, Earth and Fire Elemental|
|First appearance||Episode X: Jack and the Lava Monster|
|Last appearance||Episode X: Jack and the Lava Monster|
The Lava Monster is a giant made up of the stone and magma he was imprisoned in. He had spikes that protruded from his shoulders and was easily three times Jack's height. When he was human, he was blonde, tall, and had a muscular build.
The Lava Monster is similar in personality to Jack. He is a strong warrior who fights for the ones he loves, but takes more pride in his actions. He nonetheless possesses a great sense of honor, refusing to strike an unarmed Jack down when he refused to fight back.
Centuries ago, possibly even around Jack's time, the Lava Monster was a human warrior and leader of a Norwegian tribe. He lived a peaceful life with his loved ones until one day when Aku appeared. Try as they might, the warrior and his forces were crushed almost instantly by Aku. To punish the warrior, Aku sealed him within the Earth and made him immortal, making him unable to pass on and join his people in Valhalla, the hall of slain heroes. After countless years of being stuck in the Earth, the warrior learned how to mold the earth around him to create a shell he could use to move and escape his tomb. He then created a perilous cavern and drew heroes to him, hoping that one would be mighty enough to pass through the cavern safely and defeat him.
While travelling through a field one day, Samurai Jack began to hear a voice calling out to him. The voice soon led him into a treacherous cavern full of booby traps and the corpses of many before him. After successfully reaching the end, the Lava Monster revealed himself and battled Jack. However, seeing the monster's eagerness to fight, Jack refused and sheathed his sword. The monster begged Jack to continue fighting, then told Jack of his past and his desire to pass on to Valhalla, the only way to reach it being to die in true combat with another warrior. Jack decided to resume fighting the Monster to try and free it. After a fierce battle, Jack defeated him and freed the Warrior of his shell, but the Warrior began to rapidly age. The Warrior thanked Jack, and when he died, a pair of Valkyries descended in a beam of light to carry the Warrior to Valhalla. Before he left the cavern, Jack drew on the Warrior's obelisk a picture of the Warrior and the word FREE in stylized runic. When Jack resumed his journey, the Warrior could be seen looking down on him from the heavens in the company of the gods of Asgard, Odin among them.
Powers and Abilities
- Master Swordsman: Although not in the same caliber as Jack, the Lava Monster was proficient in the use of swords. His skills were great enough that he could last against Jack for a long period of time.
- Master Combatant: While the sword was obviously his weapon of choice, the Lava Monster still demonstrated the ability to use other weapons, as he had formed a mace from his arm. In his recital of the story of his past, he was also shown to wield weapons such as a spear and a bow. This could possibly mean he has, at the very least, a good understanding of other weapons and tactics.
- Elemental (Fire and Earth) Control: Due to his imprisonment in the Earth, the Lava Monster gained a link to his prison, letting him control it and mold it to his liking. He used this power to create his shell and the cavern in which he lived and waited for a hero to come and best him. He could also mold his arms into weapons and form a metal sword out of stone.
