Ella Dee is a fictional character and a witch in the British television series Hex, played by Ulster actress Laura Pyper.
One of the most impressive examples is in the first episode of season two, where she uses her telekinesis to control strings of lights to catch a lunging Nephilim and then electrocute it to death.
In some cases Ella is also able to control and maybe create fire, which may be an extension of her telekinesis (though due to trauma during her witch trial, she is left pyrophobic).
As an Anointed One, Ella is immortal until she fulfills her destiny and can harness the power of lightning to kill herself, cross the realm of the dead, and be reborn.
Her years of training and experience as an Anointed One means she is adept at casting spells and performing rituals, skilled at different forms of hand-to-hand combat and proficient with many weapons such as swords.
