Dreamy Luigi

Dreamy Luigi is a character who has appeared as a starring character, acting as Luigi in the Dream World of the game Mario & Luigi: Dream Team. In this game, Dreamy Luigi makes a team with Mario to explore the Dream World and defeat Antasma.

Abilities
Dreamy Luigi's abilities in the 2-D levels on the Dream World, will consist (so far showed) on the Jump and to jump-into the Luiginary Works, are special objects found in the Dream World. When Dreamy Luigi is near a Luiginary Work, both react to each other, causing them to be surrounded by a green light. Dreamy Luigi, then, can "possess" the object, creating a special object that can be controled by the sleepy Luigi, with Starlow's help.

Also, it seems that when Dreamy Luigi is in a crisis, many Luiginoids "fuse" with Dreamy Luigi, making him giant, similar to Bowser in Mario & Luigi: Bowser's Inside Story.
