Doctor Double X (Simon Ecks; originally called Doctor X and Double X) is a supervillain appearing in comics published by DC Comics. He has fought Batman several times in Gotham City. [1]
Doctor Double X first appeared in Detective Comics #261 (November 1958), and was created by writer Dave Wood and artists Bob Kane and Sheldon Moldoff. [2]
Simon Ecks is a scientist who discovers that human auras can be enhanced to function outside of the body. Using this knowledge, he creates an energy clone dubbed Double X and battles Batman and Robin on several occasions. [3] [4] [5] [6] [7] [8]
In The New 52 , Ecks' energy clone is depicted as a Tulpa and is vulnerable to Nth Metal due to being a spirit. [9] [10] [11]
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.
Doctor Double X appears in Justice League Adventures #29. [14] This version became stranded in Dimension X, a zone located between space, after stealing a teleportation device from Japanese scientist Ryko. In the present, Double X uses the device to wreak havoc on Earth before the Justice League defeats him and he is imprisoned.
