Trueman's victims include a large number of people that Trueman sent to the World of Darkness by materializing through the cards of duelists who have felt negative emotions and assuming their form, but not before getting rid of the original. When he does this, everyone who knew the person forgets they ever existed.
At Duel Academy while looking at a list of all the students, Alexis, Chazz and Syrus thought that there were more students once at the academy but that they can't remember any of the people they had dueled that day. Atticus, who was also present, did not remember there being anymore than those listed.
While in Domino City, Axel Brodie looked up a list of names on a computer screen inside a van. The names on the list began to disappear one by one as Trueman took them. Axel then dashed from the van and went to KaibaCorp.
Here he found a list of people employed by KaibaCorp. Names on that list began to disappear with Seto Kaiba's name being the only one to remain. Later Trueman's master, Nightshroud, revealed that it had created an artificial solar eclipse over the planet, with its own dark world blocking out the sun, which assimilated all humans on Earth into the World of Darkness
This left Jaden, Pharaoh the cat and the immaterial Lyman Banner, along with Seto Kaiba as the last known life on Earth. It can be assumed everyone in Domino City and the world were rescued from World of Darkness after Jaden defeated the malignant entity.
Names from the lists include
|Yukari Kurihara Masato Kamimura Tomoyuki Satake Akira Hukui Manami Kumeta Chie Ookawachi Misaki Oota|
|Kazuhiko Mashirito Aoi Kisaragi|
