The Chaos Staff, also called the Staff of Cleopatra, is one of Cleopatra the Jackal's scared relics, the other being her gauntlets. It is a powerful staff originally wielded by Cleopatra and could only be controlled by her users of white fire.
It is unknown when the Staff was actually made, but it first appeared when the Chaos Bow first appeared before Voltage the Tiger and later infused with Cleopatra's powers of Electrokinesis/Lightning. Only a descendant of Cleopatra can control the staff.
According to the legends, it is said that it is possible that the Staff was embedded with the power of the Chaos Emeralds allowing the user to Teleport. Eventually, the staff was passed down through the Cleopatra bloodline and soon came into the hands of Seth. However, when Seth was born, the staff did not see him as the new owner, despite him being a descendant. Until the true owner was recognized, Seth held onto the staff, using it as a melee weapon.
The Staff has a minor appearance. It first appears at the start, where Seth is looking at it, and then at the end. Seth is watching the crystal flash shortly after Zarina's birth...
The Staff appears shortly after it is revealed that Seth is Zarina's real father and when her Lightning powers finally manifested.
