Bustbox has the ability to control sound; however, instead of just making really loud noises like most sound aliens, Burstbox can manipulate the medium of sound itself, allowing her to do things like raise and lower ambient noise in the area, silence herself completely for stealth purposes, or recreate any sound she's heard before.
On top of this, her species has a much more complex auditory system than humans, allowing them to process a large number of sounds at once and detect them from a further distance.
Aside from her sound-related abilities, Burstbox's armored plating makes her extremely durable.
Burstbox's dense body makes her somewhat slow and clunky.
In Burstbox's Titania form, her ability to output sound is greatly strengthened, to the point where even an intentionally weak burst of sound can blast a 1.5 ton machine over 15 miles away. Her already powerful auditory processing capabilities are also enhanced, allowing her to hear and identify sounds from up to 50 miles away.
