Giant Luigi

Giant Luigi is a form in Mario & Luigi: Dream Team that Dreamy Luigi takes in the Dream World after uniting with many Luiginoids. When Dreamy Luigi is in a state of peril, the sleeping Luigi outside the Dream World will begin to act differently (exception: When the Bros. face the giant Bowser in Dreamy Neo Bowser Castle, Luigi is more confident, rather then scared), and Starlow will touch the L part of Luigi's cap, causing a light to grow there. As this happens, Luiginoids will join with Dreamy Luigi, causing him to grow in proportion into a giant state, allowing Luigi to take on the boss threatening him. This gimmick is similar to Super Bowser in Mario & Luigi: Bowser's Inside Story.
