Stand user: Adagio Dazzle  
Stand name: Song To The Siren  
Namesake: Song to the Siren (Tim Buckley song)  
Abilities: the Stand grants the user a beautiful singing voice and the ability to brainwash, hypnotize and manipulate people through songs, and it feeds off negative energy. The more energy it consumes, the Stand grows stronger and more destructive, being capable of attacking using strong sound waves.
 
Destructive Power: C→B  
At first relying on its brainwashed minions to cause most of the damage, the sound waves it can create after its evolution are a powerful attack.
 
Speed: A  
Song To The Siren can move up to 50m/s.
 
Range: E→B  
Initially bound to its user, after growing strong enough the Stand can move freely in a radius of several dozen meters.
 
Durability: D  
Its weakness is the jewel in its chest; if damaged, the Stand loses all its powers. The jewel can grow back, but only after a period of regeneration that can last up to a year, depending on the level of damage caused.
 
Precision: A  
All of its powers are sound-based. The closer you are to the Stand, the more effective it is against you.
 
Developmental Potential: A  
The Stand grows stronger the more negative energy it consumes, with no known limits.
