Prince Dreambert, often referred to or addressed as simply Dreambert, is a deuteragonist in Mario & Luigi: Dream Team. He is a Pi'illo viewed as the prince of all Pi'illos. Prior to the start of the game, he, along with all the other Pi'illos, is encased in a Nightmare Chunk by Antasma and the Dark Stone. While attempting to save Princess Peach from Dreamy Pi'illo Castle, he is rescued by Mario and Dreamy Luigi, and is brought out of the Dream World, where he explains the predicament. For the remainder of the game, he serves as a guide for Mario and Luigi, in a similar manner to that of Starlow, providing explanations and additional information whenever needed. Unlike Starlow, he is able to enter the Dream World to provide information there as well.

Mario & Luigi: Dream Team
Dreambert explains to Mario, Luigi, and Starlow that there are two powers in the Dream World: the Dream Stone and the Dark Stone, the latter of which was destroyed by Antasma and used to petrify the Pi'illos so thoroughly that they were presumed extinct. Dreambert requests that the three help free the other imprisoned Pi'illos as they search for Princess Peach. In-game, he explains to Mario how to use Luigi's dream powers to navigate the Dream World. He helps the brothers on the adventure along with Starlow.

Super Smash Bros. Ultimate
Prince Dreambert appears in Super Smash Bros. Ultimate as a Novice-class Shield-type primary spirit with two support slots. It simply boosts a fighter's overall power without offering any special effect. In World of Light, the spirit is located between a yellow and a red hill south-west of the entrance into the Molten Fortress on The Light Realm map. Its puppet fighter is Luigi, fought on the Battlefield form of the Magicant stage where the floor induces sleepiness.
