The Sirens sometimes take the form of three very beautiful maidens with hypnotically angelic voices.
In the SeriesEdit
They lure Herry to Cronus with their songs, which seem to affect only males. Their true forms are large hideous black-feathered bird-like creatures and are used by Cronus to attack the others while he has Herry performing the Labours of Hercules. They are destroyed by Cronus after they accidentally lead Jay and the others to where Cronus is keeping Herry.
