The sound from the video above is taken from the first drama track of Japan's Remastered Tracks Rockman Zero Telos album, and adds in some fitting footage from the Mega Man X series' cutscenes, the Japanese commercials for the Rockman Zero games, and more to create a more visually engaging interpretation of the narrative to sum up the conclusion of the Elf Wars and the sealing of Zero.
The video's creator, Jam Zx on YouTube, is working on a second video which features the battle between Zero and Copy X. In the meantime, a "Nightmare of Zero" AMV has been uploaded to his account, and you can find it here.
Update: At the request of those whose works had been pilfered and used without permission nor credit given, we elected to remove the video and links to the creator's channel and other works. The issue has since been resolved, and credit will be given to the artists whose works were used.
