Demyx Demikkusu was first introduced in Kingdom Hearts II. He is also referred to as the quotMelodious Nocturnequot. Demyx is voiced by Ryan O039Donohue in the English version of Kingdom Hearts II and Kenichi Suzumura in the Japanese version. Demyx first appeared in Kingdom Hearts II at Hollow Bastion with the other Organization XIII members. He later appeared in the Underworld the world in which he first removes his hood. He is confronted for stealing the Olympus Stone an object that protects the bearer from the effects of the Underworld. He refers to Sora as Roxas having been given orders to quotuse aggression to liberate Sora039s true dispositionquot but nevertheless still proclaiming quotthey sent the wrong guy for thisquot. He fights Sora with the use of his water abilities and sitar to create duplicates giving the player a time limit to defeat them all and leaving after losing. The two cross paths again at Hollow Bastion during the Heartless attack which involves Demyx039s Dancer Nobodies. Upon being reminded that he is a Nobody and has no heart Demyx commands the quottraitorquot to be silent and uses his duplicates and water attacks Demyx fades into darkness at the conclusion of the battle.
