Seto Kaiba is the older brother of Mokuba Kaiba. He is the president of Kaibacorp and his goal is to be the Duel Monsters World Champion. Kaiba was once the champion but when he suffered his first loss ever to Yugi Muto he has been fighting to reclaim his title and glory ever since.
Kaiba is a very selfish person and condescending to everyone he meets except for Mokuba. He considers all duelists but Yugi to be inferior to him. Kaiba's favorite card is the Blue-Eyes White Dragon which he has three copies of. He also was a proud owner of the Egyptian God card Obelisk the Tormentor for a brief period of time. Kaiba has also proven himself to be a physically strong person and a man of genius intellect.
In the English dub version of the anime by 4Kids Entertainment, Seto Kaiba was voiced by Eric Stuart.
In a lesser known English dub by Odex Ltd Seto Kaiba was voiced by Christian J. Lee.
