Aelita's Temporary Deaths

Aelita has had many temporary deaths in the show, most of them being due to the fact that she is linked to the Supercomputer. This was first seen in False Start when Jeremie turned of the supercomputer and Aelita lost consciousness. Many people think it is "faiting", but in Common Interest, it showed on the doctors screen, that when the supercomputer is off, Aelita has NO life signal.
Other that that, in the final episode of the second season, The Key, the Scyphozoa manages to steal her half of the Keys (resulting in her death), allowing XANA to escape his prison on Lyoko. Her father manages to return her to life, and every memory she had lost, including a copy of her half of the Keys, which may allow her control over Lyoko after XANA's escaped from the Supercomputer. He did this by giving her his own keys to Lyoko, he was then thought to be dead until he was localized in the episode Aelita. With the keys, she was able to break the link from Xana, and now she is able to de-virtualize like the others members of Team Lyoko without the use of Code: Earth. And other than that, she doesn't temporarily die when the Supercomputer is turned off.
