The Stand "Aerosmith" has the shape of a toy airplane piloted by a very small pilot named Mr. Smith inside The plane itself can be described as a propeller monoplane fighter in a tractor configuration (the propeller situated at the front), given features resembling eyes and a mouth. Its wheels are retracted under the fuselage, and its weaponry includes two machine guns under the wings and a single bomb attached under the fuselage. Narancia has a unique method of recalling Aerosmith by spreading his arms horizontally and making the Stand land on them like a runway. The colored manga and most media featuring Aerosmith portray it as a blue and purple plane. The PS2 video game adaptation portrays it as a white and pink Stand. The anime adaptation portrays it as a primarily red, gold and silver plane.

Aerosmith also has a carbon dioxide radar that Narancia can use to find an enemy's position through their breath when they exhale. While active, a small mechanical radar levitates near Narancia's face, specifically his right eye, allowing him to see the location and size of sources as circular blips on the radar. This makes it ineffective when there is a big crowd or large fire, as it is unable to distinguish between sources, though Narancia is capable of deducing the sources based on the behavior of an individual source. The heavier the carbon dioxide emission from a given source on the radar, the larger the blip will appear. Narancia can also adjust the sensitivity of the radar in order to pick up sources on the level of small animals and even insects.
