What does SETO stand for?

Answer 1

For Yu-Gi-Oh! Seto Kaiba's name derived from the Egyptian god Set who was the ruler of darkness and chaos (which most likely reflects Seto's personality). The god Set was usually depicted as evil and vicious by most interpretors; however, it is shown that Set was worshipped by the Egyptian people as a heroic deity who was the "Savior of Ra". This bears a striking resemblance to the anime where during the first series, Kaiba was portrayed mainly as an antagonist to Yugi Muto. As the series progresses, Kaiba is shown to have a heroic lifestyle as he follows Yugi and his companions to help prevent the true villains from obtaining world domination (this was always under the alias that he was only helping Yugi so that Yugi would survive and he would be able to Duel him to reclaim the title of "King of Games").
