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 of the Dream World will begin to act differently (excluding when the bros. face the giant Bowser in Dreamy Neo Bowser Castle, at which point Luigi is more confident, rather than scared), and Starlow will touch the L on 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 Giant Bowser in Mario & Luigi: Bowser's Inside Story.
||Charge up for extra oomph!
||The player must slide upwards on the Touch Screen upon Dreamy Luigi having charged up power to stomp the enemy, where the player can slide upwards again to deal maximum damage with a bonus jump to the enemy.
||Slide fast for a harder hit! (Slap foes to the background!)
||The player must slide across the Touch Screen quickly in order to deal maximum damage with a horizontal hammer swing.
|Hammer Uppercut (Unlocked in 2nd Giant Battle)
||Slide fast for a harder hit! (Smack the foe backwards!)
||The player must slide upwards on the Touch Screen quickly in order to deal maximum damage with a vertical hammer swing.
||Attack in tandem with Mario! (Touch Mushrooms to heal up!)
||The player must tap in time to Mario's mushroom throwing. Eating a mushroom successfully heals Dreamy Luigi a bit. Once the move is completed, Mario tires and is unable to act in the next few turns.
|Drill Stomp (Unlocked in 2nd Giant Battle)
||Attack in tandem with Mario! (Spin more for a super stomp!)
||The player must rapidly slide their stylus in circles either clockwise or counter-clockwise depending on the prompt on the Touch Screen as Mario and Dreamy Luigi stomp the enemy after each of the (maximum of three) spins.
||Aim with the 3DS!
||Dreamy Luigi jumps (after the player slides the stylus upwards) into space where he grabs a Star for Mario to ride on and throws it towards the boss, Mario directing to its weak point. The player needs to aim the star by tilting the 3DS. Missing the weak point causes a "OK!" attack. Getting a direct hit will get "Excellent!" with an action replay.
|Star Driver (Exclusive to Final Giant Battle)
||Control the star to attack!
||Similar to the Finishing Bros. attack, Dreamy Luigi grabs a star. However, Prince Dreambert powers up the star, making it grow to larger proportions. Mario then rides the star like before, and if the player is successful in avoiding incoming fireballs, the attack is also successful. This is only available after using Finishing Bros. on the giant Bowser.
