Villain Overview

I am the Dealer of Destruction, The Merchant of Doom, and I seek you Samurai Jack.
~ Demongo presents himself to Samurai Jack.

Demongo the secondary antagonist in Samurai Jack. He is Aku's most favorite minion among his faithful servants and evil allies.

He was voiced by Kevin Michael Richardson, who also played The Guardian and the Pig Sheriff in the same franchise.


From deep within the bowels of the Pit of Hate, I summon: Demongo!
~ Aku summons Demongo.

In "Episode XXIII: Jack versus Demongo, The Soul Collector", Demongo was summoned from the Pit of Hate by Aku and was ordered to find, kill, and steal the soul of Samurai Jack, his master's archenemy. Demongo happily took his new assignment and pursued him immediately.

Demongo caught up with Jack in a remote canyon far away from any civilization. Demongo introduced himself and informed Jack of his intentions right away.

Samurai Jack: Who are you?
Demongo: Aku has sent me to destroy you.
Samurai Jack: Aku?!
Demongo: My master tires of your existence. You are a powerful foe. Perhaps too powerful for my master... but not for me. My name is Demongo. l have come to capture your warrior's essence.
~ Demongo makes his motives and power clear.

Demongo started the battle by summoning a warrior by the name of Titan who is fairly big. Jack tricked Titan into hitting the side of the canyon cause a huge bolder to fall and kill him. Titan died and his soul was absorbed by his master. After Titan's presumed demise, Demongo summoned four more unnamed warriors whom Jack knew and Demongo explained that they were also once enemies of Aku but he now controlled their souls. The warriors attack Jack but all were eventually defeated.

Upon seeing this, Demongo summoned them and Titan once again. Jack asked how this can be since he just defeated them and Demongo told Jack that souls can be defeated, but not killed. Demongo, after seeing his minions defeated once again, summoned every soul he has collected over the years. After a long struggle, Jack defeated the remains of Demongo's minions and figured out that the trapped souls were within Demongo. As the last soul is sucked back into Demongo's chest, Jack grabbed it and is brought into Demongo's realm. Once inside, Jack released the souls of all of the warriors in Demongo's possession.

As a side effect, Demongo loses all of his powers, rendering him powerless and in some way, half-naked. As if nothing can get any worse for him, all of the warriors he has kept in enslavement are free to take their revenge. Demongo ended up being "killed" and was trapped within a skull-like prison. He then finds himself in Aku's hands and begs for forgiveness. Aku thought it over for a moment, but ultimately decided against it and seemingly killed Demongo by crushing his prison.

Aku: You have failed me Demongo.
Demongo: No, Master. Please forgive me!
Aku: Hmmm... (thinks about it) NO. (crushes him) Once again the saga continues.
~ Demongo's apparent demise.

In "Episode XCVII", it is revealed that Demongo somehow survived his apparent death at Aku's hands, possibly implying that Aku just severely punished him for his failure instead of killing him, and is searching for the souls of powerful warriors in order to replace the ones he lost fighting Jack. When Demongo busted into the older Da Samurai's bar looking for souls, he quickly realized that he was looking in the wrong place and left in order to search in the correct place.

In "Episode CI", after Jack successfully destroyed Aku from the past, it's likely that Demongo was erased from existence in the process as he was apparently Aku's creation. However, if that was not the case, it is possible that Demongo still exists in the new future, but as the Pit of Hate was destroyed when Aku was killed, Demongo was most likely never summoned.

Samurai Jack: Battle Through Time (Alternative Story)


Demongo: You cannot win, Samurai! I am more powerful!
Jack: A power fueled only by the strength and skill of the great warriors whose essence you have stolen, Demongo! Without that, you are nothing!
Demongo: Heh, heh, heh, heh, heh. You are wise, Samurai... but who cares?! Bleah!!
~ Demongo and Jack.

Similar to Aku, Demongo is completely evil, ruthless, manipulative, and diabolical, but is more cowardly and pusillanimous than his master. He does not fight his own battles but summons the essence of mighty warriors to fight for him. Demongo is obsessed with collecting the essences of powerful warriors and beasts to increase his own power. However, he likely had some level of formidable ability, as he most likely had to defeat at least one powerful warrior to begin his collection. He sees Samurai Jack as just another addition to his collection. His voice is quite high-pitched and whenever he says master, he says it like "mast-aa", with the final syllable almost in a whisper.

Powers and Abilities

Samurai Jack: I know these warriors!
Demongo: They too, were once thorns in Aku's side. But now I, Demongo, control their essence, as I will control yours. Prepare yourself, Samurai, for... annihilation.
~ Demongo summons a few warriors Jack has met in his travels.

When he first appears to challenge Jack, Demongo is shown to be capable of teleporting from one place to another at astonishing rates, catching Samurai Jack off-guard.

The demon's main ability, however, allows him to absorb the souls or "essence" of warriors he or others have defeated. When he wants to summon one of these warriors, he detaches one of the skulls from his body and strikes it with a lightning-like beam, making the warrior appear in a flash of light. As long as the victim's soul is in his possession, Demongo is able to manifest their bodies as many times as he wishes and reabsorb their essence if defeated, making him a one-man army composed of immortal warriors.

Samurai Jack: How is it possible?! I just defeated them!
Demongo: Yes you did... but they are essence. You cannot defeat essence. You may defeat them again. And again. And again. But I command the essence of thousands of such powerful warriors! Even one as mighty as you cannot defeat them all...
Samurai Jack: We shall see... [Demongo laughs]
~ Demongo reveals his deadliest ability to Jack.

Demongo controls these warriors' souls by trapping them in some sort of dimension within his body. When Jack entered Demongo's body by holding onto the essence of a defeated warrior, the souls were motionless, sitting in a circle of blue fire. By breaking the circle (presumably with the help of his magic sword which can only harm evil) Demongo's control over the souls was broken and the souls were forcefully released out of his body.

It's also possible Demongo has the ability of resurrection since when Jack released Demongo's hold on his victims' souls, they were restored to life rather than passing on, though it is unclear if Demongo could do this willingly or not. Demongo himself was shown to be back in the world of the living in Episode XCVll, long after Aku (presumably) executed him for his failure.


Demongo: What is thy bidding, my master?
Aku: You are one of my most powerful minions. You possess the ability to steal the essence of the mightiest of warriors or the deadliest of beasts. You have never failed me.
Demongo: The more essence I take, the more powerful I become, my master. And I have stolen the essence of the greatest of warriors. I cannot be defeated.
Aku: Find Samurai Jack. Destroy him and enslave his essence.
Demongo: Samurai Jack. A prize indeed. The greatest of all warriors.
Aku: Yes. What better way to get rid of him than have his essence imprisoned for all time?
Demongo: It is as good as done, my master.
~ Aku sending Demongo to capture Samurai Jack's soul.
You are a fool, samurai. Do not meddle in things you do not understand.
~ Demongo to Samurai Jack as their battle begins.
You've met your match, samurai! Crush him! Crush, crush, crush, crush, CRUSH!
~ Demongo ordering the Titan he summoned.
~ Demongo after the Titan is defeated.
Destroy Samurai Jack! I want his essence!
~ Demongo summoning undead creatures to attack Samurai Jack.

When I have your essence, I will be the greatest warrior!
~ Demongo taunts Jack.
Demongo: I... have...RETURNED!!! [everyone turns around to see Demongo the Soul Collector] I, Demongo, have come to collect the souls of the greatest warriors! [pause as everyone stares at him] But I see I have come to the wrong place. [leaves]
Da Samurai: [whistles] We got some straight-up freaks comin' through this place.
~ Demongo announcing his reappearance upon entry in Da Samurai's bar.


  • One of his quotes belongs to Darth Vader from the Star Wars franchise.
  • Demongo is quite unique among the roles of his voice actor, Kevin Michael Richardson since while the actor is mainly known for his deep voice, Demongo was his first chance to use a higher pitch for a character.
