The Guardian is a tall, muscular man with blue skin and red glasses. He is incredibly confident and loves the thrill of combat. He also sported a black suit with a black over coat reminiscent of Morpheus from The Matrix.
The Guardian appears after Samurai Jack manages to find a time portal thanks to the help of many animals. The Guardian challenges him to a fight and if he could win, Jack could go home. Despite using every skill and strategy at his disposal, Jack was beaten, and the Guardian would have killed him had not the portal which now revealed itself to be a sentient being convinced him to spare Jack, foretelling that Jack would have to fight for many years before he would return.
Abilities and Skills
Super Strength: The Guardian's muscular build gives him incredible fighting strength as he was easily able to pummel Jack without too much effort.
Super Speed: Despite his large mass, the Guardian could move with great agility, dodging attacks and easily keeping up with the nimble Jack.
Endurance: The Guardian has immense endurance. He withstood missile fire and fierce attacks from Jack with only his clothing getting destroyed and getting annoyed.
Weapons Specialist: The Guardian used an incredible variety of weapon against Jack from his own sword to guns, and even rocket launchers.
Battle experience: In his own words, the Guardian has been guarding the time portal for "countless eons", and has denied (defeated) everyone who came. After such a long time he gained lots of fighting experience, as shown when he almost effortlessly beat Jack in a sword fight.
The Guardian was one of the only two characters to actually defeat Jack and by himself. The other was the Imakandi.
