This cube craft paper toy is Seto Kaiba (or just commonly referred to as Kaiba), the majority shareholder and CEO of his own multi-national gaming company, KaibaCorp, who aims to become the world's greatest player of Duel Monsters, based on the manga Yu-Gi-Oh! (also named as “Game King” or “King of Games”), this paper craft was created by alonso jacobo.
To accomplish this goal, he must defeat his arch-rival, Yugi Muto. Kaiba is largely considered an anti-hero, as his motives are usually ego-centric and his relationships with the protagonists are antagonistic, but in several cases his actions are towards a good cause. He is the older brother of Mokuba. Priest Seto is his Egyptian incarnate.
Among one of the recurring plots is Seto Kaiba being forced to deal with either people adversely affected by Gozaburo Kaiba's actions, wanting to take their revenge on Kaiba himself, or people from within KaibaCorp attempting to take over the corporation.
In the original Japanese version of Yu-Gi-Oh!, Kaiba omits honorifics and has a "rude" pattern of speech. Kaiba uses the word "ore" to mean "I" instead of the usual boku; ore is a boastful way to say "I" in Japanese. Kaiba usually calls Katsuya Jonouchi (Joey Wheeler) names, such as "bonkotsu" (mediocre), "make-inu" (pathetic dog, loser), "uma no hone" (a nobody), and "zako" (insignificant person, weakling). This name calling was carried over to the English dub.
In the English version, Kaiba has a certain contempt for Yugi's group of friends; he refers to them constantly with derisive nicknames such as "the nerd herd", "the dweeb patrol", or "the geek squad". Plus, he is fairly condescending and scathing to everyone, with the exception of Mokuba, the only person he is consistently shown to treat with love and care.
However, Kaiba has compassion for children - especially orphans. Kaiba also threw himself between Zorc and 2 Egyptian children and flew into a rage when Zorc killed those children instead of him first. He is also shown, deep down beneath his stony, ice-cold exterior, to be incredibly lonely, and wishes to be more open with people, but is unable to do so because of his belief that everyone is alone. This portrayed personality is also very likely because of the years of systematic emotional and psychological abuse of his adoptive father. At various points during the series, he opens up momentarily, performing kind acts, though always covering them up with sarcasm, and denying them if asked. These occurrences increase in frequency towards the later series - indeed at the end of the last arc, he is visibly hurt when Joey accuses him of having no friends.
Although Kaiba may seem very unkind toward his brother Mokuba, he has a brotherly love for him. When their adoptive brother Noah had hypnotized Mokuba into not remembering him and thinking Noah was his real brother, Kaiba revealed how much he cared about him to try to make him remember. Indeed, Kaiba even tells Yugi after Pegasus is defeated that Mokuba "means everything to me." This is shown when Kaiba risks his own life by standing on a ledge to win the duel against Yugi so that he can get to Pegasus to save Mokuba. And even when Kaiba preaches that no one gets away with trying to takeover his company, he risks KaibaCorp. when he is dueling Noah for Mokuba.
Like the Pharaoh, pride is Kaiba's strength and weakness, never backing down from a fight and giving everything in a Duel. This results in his sense of superiority and sense of arrogance, making it extremely difficult to earn his respect, and causes him to look down on and treat others as inferior until they do so. This gives him difficulty when forced to rely on others and work as a team. His pride in himself and his accomplishments is a prominent part of his character throughout the series, and he reacts harshly to those who threaten or infringe on it - though it is toned down slightly towards the end.
Also, Kaiba dislikes other people using his cards, namely his "Blue-Eyes White Dragon". This is shown in Yu-Gi-Oh! - Episode 001, when he rips up Solomon Muto's Blue-Eyes White Dragon after winning it so that it could never be used against him, and also in Yu-Gi-Oh! - Episode 136 when Kaiba becomes very angry when he finds out about Joey using his "Blue-Eyes White Dragon" in their Duel. Kaiba goes so far as to attack Joey's "Blue-Eyes White Dragon" with his own, destroying both in the process, to prevent Joey from using it for another turn. He also despises Pegasus' "Blue-Eyes Toon Dragon", saying it strips the original of all its pride. According to Takahashi, Kaiba's obsession with the "Blue-Eyes White Dragon" stems from the feelings between Kisara and his ancient Egyptian incarnate, Priest Seto. More likely than anything would be it having to do with wanting to have the strongest deck possible out of any duelist as part of his domination motif, as he went through great lengths to acquire the three copies he presently has.
One of Seto's recurring traits in the English version is his absolute refusal to believe in the powers of magic often used in the series. Later on, during sagas like Waking the Dragons, he openly admits to believing in all the supernatural events occurring around him, instead of just ignorantly saying they don't exist as he always does. Also, in the Japanese version of the Yu-Gi-Oh! The Movie: Pyramid of Light, Kaiba stated at the end that the only reason he tried to destroy the Pyramid of Light card during his duel with Yugi was because if the card really was magic, it would mean he didn't defeat Yugi using his own strength and he refused to win that way. However, the closest in the English version that Kaiba has come to this is "Maybe there is some truth to this junk" in the final episodes; however, when questioned by Joey, he quickly denies he ever said such a thing. Kaiba is much more accepting of the powers of magic in the Japanese version.
In the Memory World arc Kaiba's past self, Priest Seto, is introduced. Priest Seto is depicted as being less antagonistic than modern-day Kaiba, and is portrayed as being very loyal with a strong sense of justice. However he maintains Kaiba's cockiness and cunning.
