Prince Dreambert

Prince Dreambert is a major supporting protagonist of Mario & Luigi: Dream Team Bros. He is the prince of the Pi'illos.

History
Dreambert is trapped in a nightmare block at Dreamy Pi'illo Castle and is in a hurry after being released. Mario, Luigi and Starlow find him at Mushrise Park where it is frenetic to find other Pi'illos. Mario and Luigi offer their help while they are also looking for Princess Peach. Dreambert willingly accepts and accompanies the brothers in their quest.

Later at Dream's Deep, Dreambert met his old enemy Antasma for the first time since his imprisonment in a piece of a nightmare. Even with the help of Dreamy Luigi, Mario couldn't defeat Antasma who teams up with Bowser. With the help of Eldream Eldream, the eldest Pi'illos, Dreambert and the others are transported out of Dream's Deep and into Mushrise Park. Towards the end of Mount Pyjamaja, Dreambert presents Warp_Pipes to the brothers.

Finally, at the Neo Bowserium, Dreambert faced Antasma for a short period of time in order to recover the Stone of Dreams. Unfortunately, Dreambert lost the fight and Mario and Luigi were left to their own devices. The Bros also later fought Dreamy Bowser who swallowed a piece of the dream stone. Dreambert finally regained consciousness and celebrated the return of all the Pi'illos to the island of Pi'illo.
