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 form 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 controlled 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.

Personality
Dreamy Luigi is like Luigi; He's cowardly and clumsy, but sweet, brave, and Loyal to Mario. He seems much more brave though. Dreamy Luigi is also manifested from not only Luigi's dreams, but his emotions and love for his brother; always willing to help him out despite the danger. It seems the love he shares with his brother, mixed in with the fear and worry is the reason why he is able to transform into Giant Dreamy Luigi.
