Here we have every visual of XANA activating a tower on Lyoko (give or take one hidden in a glacier).
Some animation sequences have been used more than once in the show, and only the first use of that sequence is included in this video. Nevertheless, all sequences where you visually see the Towers activating are included.
Tidbit: XANA had two main growls whenever he activated a tower, with a rarely used third growl heard in "The Key" when he activated the first of 4 towers (2:11). The growls were never heard again after "Lyoko Minus One", replaced with worrying violin stings. Pulsations also appeared for the last time in this episode.
The first main growl can be heard at 0:05, 1:55, 2:01, 2:13, and 2:17.
The second main growl can be heard at 0:10, 0:24, 0:32, 0:46, 1:06, 1:29, and 1:45.
