Majin Buu's Original abilities (From the Fandom Wiki)
(Some of these abilities will be developed later in the story) Instinctive abilities will have a * next to them
Flight – The ability to fly with the use of ki.
Ki Sense* (weak innate sense) – The ability to sense Ki. Kid Buu was demonstrated to use this when he sensed Goku and Vegeta powering up and warped to their location on the Sacred World of the Kai (which the two Saiyans deliberately allowed for specifically to lure him there).
Ki Blast – The most basic form of energy wave. Although a basic attack, when used by Kid Buu it still had enough power to destroy a planet the size of the Earth.
Unknown, unfathomable power – Buu possess an odd ki signature that makes it hard to tell how strong Buu really is. Whether Buu's power level is incredible, or not that much is unknown even by Majin Buu.[41]
Paralyzing Gaze* – Buu narrows his eyes and stares at his foe, and due to his raw power, the foe is rendered almost completely immobile. Only works on foes who are much weaker than he is.
