Like Dooku she is a plesiosaur, but lacks cybernetic implants.
She's also surprisingly nimble on land.
Ailyn is manipulative and seductive, able to play with other's minds and stimulate sexual arousement in males, though she only does this to her enemies.
She's not completely selfish though, as she loves Dooku with all her heart.
She's named after Ailyn Vel of Star Wars, but her personality is more like Elektra King of James Bond's The World Is Not Enough.
