Evolution episode #11 - Rendezvous
 
ImageObjective: Prevent the heroes from getting rid of the spectre attacking on Earth.

From there, she determines a small time window during which the towers are activated at the same time, allowing the heroes to enter and deactivate the two towers simultaneously.
 

Evolution episode #13 - Friday the 13th
 
ImageObjective: Destroy the Skid and thus block the heroes from accessing the Cortex...as well as to the towers within it.

Description: XANA infects the Skidbladnir by activating a tower in Sector 5...a manoeuvre it disguises by launching a distraction attack on Earth.

Odd is the only one who is able to dive into Lyoko and handle this tricky problem.

Countered by: Odd, Jeremy, Aelita, Laura.
Odd undocks the Skid, gets it out of the Hangar and maintains it at a sufficient altitude long enough to give his friends time.

After finding out what to do, the trio of geniuses dictates the instructions to Odd.

All the monsters sent into the Cortex's Core Chamber were defeated in the end.
 

Evolution episode #21 - False Pretences
 
ImageObjective: Gain time for the spectre attacking on Earth by preventing the Lyoko Warriors from reaching the activated tower, with the help of perfect doubles of the heroes: doppelgängers. Appearing in large numbers, they sow doubt among the heroes.

Procedure: The fist double, one of Ulrich, devirtualises Yumi when she's not paying attention. The second double, Odd, starts a fight to which the real Ulrich falls victim. The two last doppelgängers (Odd and William) create confusion in front of the tower, making the heroes lose precious time.

Countered by:William and Odd defeat most of the doubles. In the end they are aided by Jeremy and Laura, who improvise a program to make the doppelgängers glow.
 

Evolution episode #22 - Mutiny
 
ImageObjective: Send the Schyphozoa to re-Xanafy William, like in the past.

ImageObjective: Set a trap for the heroes to hack the Supercomputer and most of its key functions.

Procedure: XANA lures the heroes onto the Network with the help of a data-packet similar to the one Hopper used to use. Arriving at the signal source hub in the Skidbladnir, the heroes fall into the trap. The hub's defence system, a massive pincer, grips the Skid and transmits a virus into it. The Skid loses all functionality and is destroyed by Sharks. Also, the Supercopmuter is hacked through the vessel's link with the Supercomputer. The Superscan and the Holomap are rendered non-functional.

Countered by: Nobody. Jeremy and Aelita can only fix the damages afterwards.
 

Evolution episode #23 - Jeremy's Blues (B)
