D.N.Angel - Krad
Krad is an entity similar to Dark, living inside his tamer, Satoshi Hiwatari. He is the complete opposite of Dark and his worst enemy. He has also been shown to be very confident, almost to the point of being arrogant. Krad is portrayed as a very calm and proper person. His actions show otherwise, as he enjoys the suffering of others, especially Daisuke and Dark.
