Fictional character biography

Dr. Simon Ecks is a scientist who discovers that human auras can be enhanced to function outside of the body. When Ecks creates an energy-duplicate of himself, his mind becomes dominated by the doppelgänger he names Double X. He battles Batman and Robin. The resulting battle causes Ecks to lose his memory of the experience, after which he is remanded to Arkham Asylum.
Some years later, Ecks regains his memory and develops another duplicator device that enables him to escape from Arkham Asylum. Doctor Double X matches wits once again with Batman. This time, Batman is able to defeat him by building his own machine that generates an energy duplicate of himself.
Doctor Double X later escapes from Arkham Asylum and faces off against Batman and Superman. This time, it takes both Batman and Superman to overcome him.
Doctor Double X trades opponents with Rainbow Raider after meeting with motivational therapist Professor Andrea Wye. Both of them are defeated by Batman and Flash.
In "The New 52" continuity reboot, Batwing encounters Simon Ecks in the tunnels beneath Arkham Asylum. Ecks warns Batwing to stay back, as there is something inside him that wants to kill. As a spirit rises from his body and starts to reach towards Batwing, Jim Corrigan appears and knocks out Ecks, stating that the spirit is a Tulpa.

Doctor Double X's energy duplicate shares his consciousness, but can also act alone. It also has the powers of flight, super strength, and creating energy blasts, but requires regular infusions of electrical energy to sustain itself or else it will become dormant.
