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. He shoots giant fireballs, which the Bros. need to jump at the same time to dodge them. He also clones himself to shoot double the fireballs. Dreamy Bowser also can create multi-coloured minions from portals to charge at the Bros. Other attacks include Bowser summoning a giant hammer to hit the bros. with repeatedly, creating an airship to open fire at the bros. from the background, and even creating a huge pile of food in the background which heals him when he eats it (he will endlessly spawn food and heal as long as his minions are not defeated)

The koopa king is initially invulnerable: whenever the bros. try to attack him, he will shield himself from attack with one of his arms. Like Queen Bean before him, Bowser's arms need to be defeated before Bowser himself can be attacked.
