Dreamy Bowser

Dreamy Bowser is an enhanced form of Bowser and is the final boss of Mario & Luigi: Dream Team. He is created when Bowser inhaled the shattered remains of the Dream Stone. While in this form, Bowser is much larger, glows with bright colors reminiscent of those of the late dream stone, and has objects resembling the Dream Stone on his head and stomach.

Mario & Luigi: Dream Team
After Starlow and Peach destroy the Dream Stone, Bowser inhales the broken pieces of it and transforms into Dreamy Bowser. He then engages Mario and Luigi in combat, and is defeated by them. He then transforms back into Bowser and is knocked out of his own castle with the brothers' hammers.

In Battle
Dreamy Bowser's attacks consist of using the Dream Stone's amazing power. One attack of this form of Bowser involves shooting giant, rainbow-colored fireballs, which the Bros. need to jump at the same time to avoid. He also clones himself to shoot double the fireballs: each of the fireballs shot by the clones can only strike a single brother. Dreamy Bowser can also create multi-coloured minions from portals to charge at the Bros; after summoning these enemies, Bowser will retreat to the background, where he will heal all his body parts 200 HP every turn by eating endless piles of meat until the minions are destroyed, if the Bros. manage to avoid getting struck by a sufficient number of his minions during an attack, Bowser will also slam his fists into the ground to create a shockwave that must be jumped over, and any attempt to attack Bowser while he is in the background will result in the Bro that initiated the attack being struck with lightning. A third attack begins with Bowser summoning a giant hammer, which he subsequently tries to hit the brothers with; Bowser will drop a coin with the Bros. initial on each side to reveal which brother will be attacked first and thus which brother will first need to pull out his own hammer to stop Bowser's hammer. Bowser can even create an airship with rainbow-colored Shy Guys that will chase a brother, the remaining Bro must repeatedly attack the airship with his hammer while the chased brother jumps over the fireballs it generates. The airship will go into the background if it survives this attack and will shoot cannonballs every turn, the left cannon on the ship will shoot cannonballs at Mario, the right one at Luigi, and the middle one will simply not hit anyone. These cannonballs will damage the airship if successfully struck with a hammer. A final attack involves Bowser growing giant, forcing the Bros. to make a run for it; Bowser will soon start chasing them while spewing 3 massive streams of moving fire that must be jumped over and which deal massive damage if they are not jumped over successfully.

Bowser's arms are very important in this battle in the sense that Bowser can only perform certain attacks and actions with his arms present. His right arm will periodically be used to grab a brother, the remaining bro cannot use Bros. Attacks while the brother is being held, and Bowser will throw the brother either that turn or within a few turns if the right arm is still intact, forcing the remaining brother to catch the thrown brother by rapidly pressing their jump button to dash: the thrown brother will take damage every time he bounces off the ground.

His left arm is even more important, it will completely shield Bowser's body from damage while it is still active. The Bros. need to disable this arm before attacking Bowser's body and thus defeat him.
