@Jinbeifan1: Jack. Not. Much? of all the...
Speed: the 3 archers that create a rain of arrows in seconds that Jack past blindfolded. Jack is shown to be extremely swift on his feet and has performed incredible feats of speed and agility, able to avoid machinegun-fire, carve through entire robot armies within seconds and in one instance, defeat an team composed entirely of highly infamous and skilled bounty hunters in the time it takes for a drop of water to hit the ground from what looks like less thatn 2 meters, and he didn't even know they were planning a trap for him. So he is gonna be hard to tag
Jack can almost fly from that stone training with the caveman. He was literally levitating. and this ep was way before his encounter with the gaurdian.
Durabillity: The Guardian has immense endurance. He withstood missile fire and fierce attacks from Jack with only his clothing getting destroyed and getting annoyed(the missle didn't even push him).
Weapons Specialist: The Guardian used an incredible variety of weapons from his own sword to guns, and even rocket launchers.
