Samurai Jack Season 3 Episode 6
To get to a time passage, Jack must pass a lake which sucks down any who try to cross it without touching its bottom. The locals summon an ancient creature who can walk upon the bottom but tall enough to stay above the water. It puts in a good word for two other creatures: a crawling creature that helps Jack pass a mountain and a flying creature that flies him to the portal. Jack must face its Guardian, a mighty warrior with an unlimited arsenal of weapons and incredible strength who says the only one who may pass is the one destined to use it. Ultimately Jack is defeated and the Guardian sends Jack back, as a mysterious warrior (apparently an older bearded version of Jack) within the time passage apparently tells the Guardian that Jack can’t use it . . . yet.
