Ep 14. Karate Koopa

In Super Mario Bros. Super Show season 2 episode 14, titled "Karate Koopa," the Mario Bros. find themselves in a new adventure as they discover a dojo with a scroll that reveals the secrets of the ancient martial art form of Karate. The duo learns that Koopa has also found out about the scroll and plans to use it to train his minions to become unbeatable in battle.

With the help of Princess Toadstool, Mario and Luigi seek the guidance of Master Misaki, a wise old karate expert who teaches them the art of self-defense. As the Mario Bros. learn new moves, Koopa's army shows up to challenge them to a martial arts tournament. The stakes are high, as the winner of the tournament gets to keep the scroll and become the ultimate karate champion.

As the tournament begins, the Mario Bros. put up a good fight, but Koopa's minions prove to be too tough to defeat. Just when all hope seems lost, Mario and Luigi remember a lesson they learned from Master Misaki about turning an opponent's strength against them. With this newfound knowledge, the Mario Bros. quickly turn the tide of the competition and go on to win the tournament.

However, Koopa isn't one to be beaten easily. He hatches a new plan to steal the scroll and defeat the Mario Bros. once and for all. With the help of his new Karate Koopa form, he challenges the Mario Bros. to a one-on-one showdown that will determine the fate of the dojo and the kingdom.

As the final battle looms, Mario and Luigi must use all their karate knowledge to defeat the powerful Koopa. The fight is intense and filled with high-flying kicks and quick reflexes. In the end, Mario and Luigi emerge victorious, but not without sustaining a few bruises along the way.

With peace restored to the Mushroom Kingdom, the Mario Bros. leave the dojo, proud of their new karate skills and grateful for the lessons they learned from Master Misaki. The episode ends with the Mario Bros. driving off in the Mario Mobile, ready for whatever adventure comes their way next.
