...Yu-Gi-Oh!

Characters

Noah Kaiba (Noa) is very much an enigma at this point. He is Kaiba's step brother and has no physical body (due to an accident).  He hates Kaiba and thinks he should control Kaiba Corp. instead.  But he doesn't believe in foul play or cheating.  Though he does believe in mind games, veritable torture and generally messing up peoples lives.  So, he isn't very nice, but he isn't a total jerk either. He's evidently very intelligent though. In the end he realizes that he cannot live in bitterness any longer and he saves the gang.

    Age: Younger than Yugi, older than Mokuba.
