Seto Kaiba
Seto is Yugi's "arch enemy." He is a cold hearted person, but it's not all his faut. When he was a child, both his parents died, leaving him and his brother alone at an orphanage. Many people came and wanted to adopt his younger brother, Mokuba, but he wouldn't let the two be separated. At one point, a man named Gozaburo came, and Seto challenged him to a game of chess. You can guess who won. Because Gozaburo lost, he adopted both Kaiba brothers. He was mean to Seto, and that made him how he is today, even though there is always a place in his heart for his brother. How sweet. As a grown man, he ownes a graphics company called Kaiba corp, and it is constantly under risk of new control. People like Pegasus and Seto's step brother, Noah, try to take advantage of the CEO's young age, and take over the corporation. It still belongs to Seto, but for how long? The world may never know. His name means "seahorse".
-His hair is short, and brown. It was green, however, in the first series.
-His eyes are brown, and you can see a hint of arrogance in them almost always.
-He usually wears a blue trenchcoat thing, or his black, silver and white battle city out fit, or his white one.
-He's older than Yugi and co. about twenty three, maybe. He is also taller than all of them.
