Samurai Jack

While traveling through the rain, Jack takes refuge in an inn and meets Da Samurai, a hip-hop singer/fighter. His performance is interrupted by a new version of Aku's bounty hunters. Jack defeats them handily, much to Da Samurai's amazement. Da Samurai challenges him to battle and Jack eventually agrees. Jack requires him to first fight with sticks and Jack is clearly the superior warrior. Their fight is interrupted by the arrival of many more of Aku's hunters. Da Samurai is captured and Jack defeats the 100+ robots...but they assemble into one gigantic multi-headed robot. Da Samurai saves Jack by taking an energy blast, giving Jack time to defeat the robot and acknowledge Da Samurai has taken the first step on the path of a true warrior.
