The true origins of the Sea Witch are shrouded in mystery and rumour. Stories of a 'sea witch' been around for hundreds of years around the Malaca Straits near Malaysia, although the creature calling herself by that name in the present day may or may not be the same creature who has appeared previously. What is known is that she preys on marine vessels travelling through the Straits and other shipping lanes in South-East Asia. Her attacks are aimed at disabling the vessels and then plundering their cargo and passengers. She has shown a shrewd interest in the illicit people smuggling operations and has often swept down on leaky boats to murder the handlers and take the 'human cargo' for her own ends. Sometimes she sells the people but other times they simply vanish.

Her activities are opposed around Indonesia by the Bidadari Angels, although their capacity to intervene is limited. There are only three Angels and a very large number of islands to patrol. In Australian territories, the Southern Knights have successfully dealt with the Sea Witch several times, although they have never managed to apprehend her. In contrast, the crime lord Evol Khan has entertained the Sea Witch in his elaborate hotels and has even extended assistance to her piracy activities. It is rumoured that she keeps a sanctum hidden in Singapore under the direct protection of Khan himself.

The Sea Witch is apparently immortal and if she was ever truly human, she has lost both the appearance and any admirable human traits she may have once possessed. She considers humans to be toys and will collect and discard them at will. She is cruel and wild and thoroughly unpredictable, seemingly able to change moods like the tides of the oceans she haunts.

"Your life in exchange for these pretty souls..."

A creature of magic, the Sea Witch is able to draw upon magical energies for a variety of effects most notably teleportation and the generation of a green energy. This energy can be used to create concave shields, powerful blasts and can be used to transform matter. She is also able to dominate minds as well as communicate with them.

In addition to these dynamic powers, the Sea Witch is immortal and cannot be harmed in any permanent manner.

With green skin, matted black hair and wild black, pupil-less eyes, the Sea Witch is a frightening figure to encounter in the oceans. She has cultivated a reputation for murder and deeds most foul. She has a lean and dangerous frame but also appears somewhat ethereal, with wisps of sea mist dancing around her. She refuses to wear anything except a torn black dress which doesn't seem to worry her as she is immune to the adverse weather conditions she may encounter.
