User blog comment:Zombine™/Fujin as DLC on MK9/@comment-422853-20110818233142

Boon did say there could be more DLC if there was an huge enough demand for it, but as of now he's got no more plans beyond Freddy.

I guess the Fujin sound clips just proves he was a considered character for DLC at one point, but then scrapped later on or something. It happens.
