Shadow Fagin

Shadow Fagin is the Heartless clone of Fagin that was sent by Mirage to control and turn Denahi into a Villain League warrior. It managed to merge the both of them into a fusion warrior similar in construct to Xehanort and the Guardian Heartless with denahi as Xehanort and S.F. as Guardian. It was eventually destroyed by Kairi's light blast, and Denahi was also vaporized as both of their hearts asceneded into Kingdom Hearts.
