Moody Blues is a humanoid Stand of a height and build similar to Abbacchio's. It is clothed from its head to its knees in a semitransparent piece of medium shade, open between the base of its neck and its crotch (revealing a light surface), and which forms a tent between its head and its shoulders. Its body is made of vinyl.
It has a depressed, digital timer on its forehead; while its eyes resemble the speakers of a cassette player; repeated on the sides of its shoulders, the back of its hands and on its knees.
Most media featuring Moody Blues feature it being white and purple.
In the anime, Moody Blues has a constant VHS static-like effect present over its body while active, with the said effect becoming more pronounced when it uses its ability. Furthermore, when activated and when using its abilities it emits sounds akin to both a landline telephone's dial-up tone and hang-up click, as well as the fast-forward and reverse winding of a VHS tape.
The series is known for alternating colors between media, the information presented below may or may not be canon.

Moody Blues Stand Rush
Moody Blues demonstrates a certain level of inherent strength, being able to perform basic rush attacks and outmatch other relatively weak Stands and their Users in direct combat, such as Illuso and his Man in the Mirror. However, its abilities do not lend themselves to fighting, which often leaves Abbacchio overpowered by other offense-based Stand Users. Despite this, Moody Blues' esoteric power makes it useful for a number of outside tasks.
Moody Blues turning into Narancia from five minutes ago
Moody Blues' primary ability is retrocognition; in particular, the ability to reenact, or "replay" past events with utmost precision, allowing Abbacchio to freely investigate events. Every event happening to a particular location or person will be exactly recreated by Moody Blues, even if it shouldn't happen; for instance, Moody Blues reenacting Narancia's past will produce music because Narancia listened to some. However, there are limits to what Moody Blues can replay, for instance, Clash's teleportation through water is impossible to reenact.
Fast-forwarding a replay
At the same time, the digital timer on Moody Blues' forehead will remain to indicate the point in time it is reenacting. The "replay" can be controlled as if it was a video, thus Abbacchio can accelerate its speed to skip uninteresting events or pause it, allowing people to interact with the paused event if need be. The farther away the event is in the past, the more time Moody Blues must spend immobile to reach it. Thus it had to remain defenseless for possibly 8 to 10 minutes because Abbacchio investigated Diavolo's past meeting with Donatella Una on the beaches of Sardinia 15 years ago.
By using a replay, Moody Blues can imitate the form of an individual for a limited time; at one point enabling Abbacchio to pilot a plane from copying the previous motions of the pilot recorded by Moody Blues. The imitation effect of its ability can also be used to disguise Moody Blues, shown when it changed into Abbacchio in order to fool Illuso's Man in the Mirror into dragging it instead of Abbacchio himself into its mirror world.
Since it cannot attack when it is "rebroadcasting", Moody Blues becomes vulnerable. Once finished, however, it can again attack.
Despite not being a Stand suited for combat, in the Vento Aureo PS2 game, Abbacchio can use Moody Blues to record his moves, such as kicks and punches, and rebroadcast them to effectively create attacks and combos for use.
