Luigi is shown to be cowardly, usually paranoid of doing things such as swimming or soccer, believing it will end in disaster. Despite his immature states he can be brave and strong such as when he protected Mario from death and fought for him in Cute Mario Bros. The Movie. He has many fears in a funny way. Luigi is generally friendly and understanding, and treats his friends with more respect than Mario. However, at times, Luigi shares Mario's selfishness and arrogance, which is greatly magnified when he becomes Cool Luigi. Luigi is shown to greatly love Mario, though the two butt heads more often than not, and get into various fights that never last long. Unlike Mario, Luigi gets along better with his friends than Mario does.
Luigi is shown to be a good climber in Super Spy Luigi: Get the Glasses!. He uses Irish dancing as an attack in Meet Jack Skellington and Cute Mario Bros The Movie.
