Mr. L, also known as The Green Thunder, is a brainwashed version of Luigi enlisted by the EVIL league.
Mr. L reappears in Boss Battles as well, a boss. He generally plays rather defensively, running and jumping more than attacking during his first phase. When he attacks with thunder balls, he can be easily punished because he just stops. During the second phase of the fight, he uses Brobot to float around the arena and shoot missiles across the arena. These missiles must be either redirected towards him or during the third phase, avoided. Brobot also has a sucking attack that can be easily punished as well.
Mr. L appears in New Super Mario Bros. The Roman Worlds as the boss in the World III Castle. He attacks by throwing green fireballs, running at high speeds and ground pounding. Mario must defeat him by blowing him up with Bob-Ombs.
