The Sky Siren is an illusion-casting witch intent on destroying anyone who enters the Great Expanse.
Physical appearance[]
The Sky Siren reveals herself as a femme fatale, with music and voices that can make an illusion of anyone who hears it, to see their greatest desire like the sirens in Greek mythology.
Abilities[]
She uses their greatest desires against them, keeping them from escaping. Her illusions manifest themselves in the form of what appear to be waking dreams.
It is thought that initial resistance will cause the sky siren to further amplify their desires, draining her energy. However it is shown in the episode "Siren's Song" that to break the spell of the siren, the greatest desire must be seen.
History[]
Many ships and people fell prey to her power until the Storm Hawks' travel to the Great Expanse. Each of the Storm Hawks fall prey to her powers, but in the end it is Radarr who overcomes her and pilots the ship to safety, the act of doing so having been his greatest desire, driving the Condor.
