Synopsis:
The Idol-Head of Diabolu unleashes another menace on the world in the form of three Venomee. The Venomee are purple people with powers that allow them to transform other people into other shapes. The Venomee seek to create a brew which will allow them to hide in human form. J'onn J'onzz tries to stop them without falling victim to their powers. He eventually uses his own shape-shifting abilities to become a Venomee and transform the purple people into humans. Without first completing their brew, the Venomee disappear completely, ending the threat.
