Episode Description:
During the school physicals, X.A.N.A. possesses the school nurse, Yolanda, and has her kidnap Aelita. The rest of the group beat her to the factory, but have no way to get Aelita from the far more powerful nurse. Having no other choice, Jeremy decides to test out an experiment which will give a person the same powers as one possessed by X.A.N.A.. To do this, he has to activate a tower like X.A.N.A.. Odd volunteers, and is enhanced by a ghost of Jeremy's design. This allows Odd to fight the nurse effectively while the others deactivate the tower. This fortune does not last. X.A.N.A. is able to take over Jeremy's tower, reversing the effect of the ghost to drain Odd's energy. Meanwhile on Lyoko's Mountain Sector, X.A.N.A. makes everything invisible. Now the group has to deactivate not only the original tower, but the tower that is draining Odd's life energy.
