X.A.N.A. wasn't even a person in a strict sense. He was a digital entity that was currently divided in two. The first half, the one in Lyoko, possessed almost unlimited power and the cold clear-sightedness of a computer, while the other, the weaker half, was still prisoner in the Mirror, and had begun to develop something new: emotions.
But now, he had to make a decision. Should he help Mago and become the most powerful digital creature in Earth’s history? Or should he help the children by giving in to this strange human component that he still didn't completely understand?

Odd was stunned by the deep silence down below. The rebreather made practically no noise, and the boy could only hear the inhaling and exhaling of his own breath. Richard and Yumi’s fins undulated in front of his face as soft shadows.

“They thought of everything, but they didn’t know how many people would go on the mission with them,” Yumi reflected. “I mean, they probably brought spare equipment. We could steal it from them and then follow them through the sewers and get to the Hermitage ourselves.”

He wondered if it belonged to the terrorists from Green Phoenix, who weren't happy about the school being closed off and were planning to attack it from the air.
The boy’s suspicions were confirmed only a few seconds later. The plane turned widely in the sky, then opened its enormous, metal stomach from which something began to exit… Small, black dots falling at high speed… Parachutists!
