I am the son of Aku's magic. He has looked deep within you and has spawned me from your own burning hatred. I am your dark side and I have possesses all the powers that you wield and I have only one purpose in my existence to destroy you!

—Mad Jack, Episode VIII: Jack versus Mad Jack

Mad Jack was one of Aku's minions and an evil personality of Jack. He was created by Aku to defeat him using his own skills against him. He made his first and only appearance in Episode VIII: Jack versus Mad Jack.

Appearance & Personality

Mad Jack was created by Aku to see if he could defeat Samurai Jack using his own skills against him. He is Jack's exact replica, except that his robe is black with red trim, his skin is paler, and his eyes are blood red with shadows under them.

Like Jack, Mad Jack is also armed with a katana simliar to Jack's sword. He has shown to be rude, violent, and rather psychopathic, completely unlike Jack. In essence, he is the physical embodiment of all of Jack's rage and frustration.


Aku had sent several bounty hunters to attack Jack, all of which failed, Aku lamented that no fighting style seemed to be able to beat Jack's, which caused him to form a plan; to pit him against himself.

After having to fight several bounty hunters, Jack became infuriated at his lack of peace and he was tired of fighting. He tried to calm down after defeating the last of them, but when his sandal strap broke, he snapped and threw the sandal at one of his wanted screens. The screen then started to light up, energy came from it and formed around the sandal, sealing the strap, until it finally forming into a more sinister Jack, Mad Jack. Surprised Jack questioned who the double was. In response, Mad Jack revealed himself to be the spawn of Aku's magic, formed from Jack's own hatred as well as being his dark side possessing all of his skills, created for the sole purpose to destroy Jack for Aku.

The two fighters then begin battle and appear to be evenly matched, trading blow for blow. However, since they both possessed equal skills, neither one could best the other. Their fight grew more intense as they continued, forcing each other's hair to sprawl out, reducing trees to ashes with the sparks of their swords, and outright destroying the area with the force of their blows.

As Jack struggled with his dark half, he saw the reflection of his own eyes in his sword and to his horror saw they bore great resemblance. Finding his peaceful center, Jack stepped back and calmed himself, causing all of his negative emotions to fade away. He then claimed the fight was over, stating that the negative emotions that formed Mad Jack were gone, meaning Mad Jack didn't exist.

Refusing to let Jack look down on him, Mad Jack boasted that he was real and charged toward Jack to deliver the final blow. However, while Jack remained in a meditative position, not even bothering to defend. As he was to strike Jack down, Mad Jack was instantly in Jack's control, able to do nothing except scream in impotent fury and defeat before he was sealed away by Jack.

Skills and Abilities


Jack vs. Mad Jack

Mad Jack's physical abilities and combat skills are identical to Jack's own. This resulted in a perfect stalemate between him and Jack when the two of them fought. However, he could only exist so long as Jack's hatred existed. Once Jack got his emotions under control, Mad Jack ceased to be.
