Standard XANA powers, Tower Activation, etc. In human form, these powers can only be accessed via his extremely hightech phone, also known as a porta-Tower. This phone also generates a unique radiation, normally only given off by Spectres. Without it for 24 hours, he will faint for a few moments as his body briefly adapts to being without the radiation. On Lyoko, they are accessed through his staff.
His human form's shadow also has the ability to move away from his body and observe others while Xavier naps. It has only displayed this ability once so far.
