|X.A.N.A. Franz Hopper|
The spectre in the computer seat.
|First appearance||Franz Hopper|
|Also known as||None|
X.A.N.A. Franz Hopper is a Polymorphic Clone seen in the episode Franz Hopper. This clone was better at deceiving Team Lyoko than most other clones. It unexpectedly appeared in the Lab and gained the trust of most of the team, except for Jeremie (whom it singled out), by deactivating towers and upgrading weapons. It used this to its advantage, fostering dissension within the team. It betrayed the Lyoko Warriors when it disabled their weapons on Lyoko and attempted to trap Aelita for the Scyphozoa. Its line, "You're the one who let X.A.N.A. destroy my diary!" gave away its true identity. In truth, X.A.N.A. didn't destroy Franz's diary, due to the timely intervention of the true Franz Hopper himself. When Jeremie declared this, X.A.N.A.-Franz Hopper reverted into a Spectre and disappeared. It reappeared minutes later and tried to suffocate Jeremie by blocking his airways.
In the episode Distant Memory, Aelita was lured into a simulation bubble of her and Franz's old home, the Mountain Cabin. However, Aelita found out that he was a fake when he didn't remember that the Skidbladnir was based on a Viking story which her father had told to her and that he didn't include Aelita's mother in the simulation bubble as well. The Franz Hopper in the simulation bubble turned out to be a Blok impersonating Hopper.
