Trueman, also known as Mr. T, is a mysterious character that appears in the fourth season of Yu-Gi-Oh! GX. As the powerful and mysterious "Messenger of Darkness" who vows to destroy those who try to deduce his agenda, Trueman serves as the emissary of Nightshroud, the true mastermind behind the vicious siege.
Trueman takes the appearance of a tall sickly-skinned man with short spiked black hair. His facial expressions are grim by default and his eyes obscured by red sunglasses. He is completely clad below the neck in a shiny black jumpsuit covered in orange lines and spikes. He produces his Duel Disk from a mass of black cards around his arm, which is merged with his suit. When taking the form of other individuals, Trueman's eyes often glow the same bright blue as those of Nightshroud.
Trueman, at one point, stated that he has no real name. He chose the name "Trueman" for Jaden to call him because he claims he always speaks the truth. However, he does tend to use deceit and manipulation numerous times in non-verbal ways as he uses illusions to prey on his victims.
Trueman demonstrates numerous abilities, the most notable being able to manifest from cards tainted with darkness, as he mentions he's a being of pure emotion. He can transform into different people and replicate their Decks. When he Duels against a particular person, he can manipulate the memories of his opponents in an attempt to psychologically weaken them. He has also shown the ability to teleport, create duplicates of himself that share these powers, manipulate objects, and hypnotize people.
Trueman initially appears to dispose of Honest, a Duel Spirit who disguised himself as a long-missing Obelisk Blue student, Yusuke Fujiwara, only to be stopped by Jaden Yuki. Recognizing Jaden as a threat, Trueman attempts to destroy Jaden, only to be thwarted fairly easily and he retreats, promising to return. Trueman returns to attack Jaden as he discusses the situation with Kagemaru and Sartorius, and Jaden Duels him while Kagemaru and Sartorius escape. This time, Trueman proves to be a much more difficult opponent, almost defeating, but he is still defeated. Multiple Trueman(s) later observe Jaden conversing with Honest, and eventually they assimilate together to dispatch Honest and Jaden, considering him as a threat to their agenda. Jaden nearly loses this one as he battles Trueman's "Five-Headed Dragons", but he manages to win using the card "Honest".
He later revives his machination and initiates a vicious assault on Duel Academy and Domino City, absorbing people into the World of Darkness by materializing through the cards of Duelists who have felt negative emotions and assuming their form, but not before eliminating the original. Additionally, when he does this, everyone who knew the person forgets they ever existed. Among the victims were Daigo Sorano, Axel Brodie, Sartorius, Sarina, Tyranno Hassleberry, and almost the entire population of Domino City and the students of Duel Academy. Names from a list of his victims, including many characters from the first series anime and manga, all disappear from the list leaving only Seto Kaiba's name behind.
To defeat Axel Brodie, Trueman copied the Deck and appearance of Brodie's father and exploits Brodie's negative emotions relating to an incident that nearly killed both of his parents. Many copies of Brodie later attempt to stop Jaden Yuki's escape from Domino City, but Jaden escapes them. However, many copies of Jaden then try to stop Jaden, but he is rescued by Sartorius.
After defeating Daigo Sorano, Trueman begins to imitate both Sorano's Deck and appearance, enabling him to blend in with the other students of Duel Academy before finding his next victim, growing stronger with every Duel. Each individual Trueman clone was capable of doing this, and so each of them would seek out students to defeat, among them being Tyranno Hassleberry and Syrus Truesdale. He later assumes his true form once more and defeats Chazz Princeton and Alexis Rhodes.
The Trueman clones observed the Duel between Yusuke Fujiwara and Atticus Rhodes as well as the Duel between Yusuke, Jaden, and Jesse Anderson. During Jaden's Duel with Yusuke Fujiwara, all the Trueman clones are destroyed by "Rainbow Neos" when it attacks and destroys "Clear Vicious Knight" and the portion of Nightshroud that was possessing Yusuke.
Trueman appears in Tag Force 3 as an opponent and possible partner.
Trueman plays a variety of Decks as he has the ability to manifest himself out of piles of random cards. To maintain consistency, he frequently runs "Dark Archetype" as a frontrunner– this can be considered his one consistently used card. In addition, he can copy the Decks of Duelists he defeats, and as such also uses a broad spectrum of constructed Decks.
