He is a secret lovechild of Lucas from "The Wizard".
"I love the Duel Disk... It's so bad". XD
I just LOVE Kaiba. He is so... adorable in his obsessive, maniacal nerdiness! Though he would definitely kill the person who called him adorable. XD
But seriously, there are times when I want to hug him, there are times when I want to faint from awesome overdose - and then there are times that crack me up. XD Like those when his unhealthy obsession with powerful cards is shown.
And still... Poor guy. Fortunately, he has Mokuba to support his sanity.
