Mortal Kombat Vs. DC Universe's roster of "kombatants" was missing some key names on both sides. That was something series co-creator Ed Boon and the MK team had hoped to address with downloadable content, which never happened.
Boon had hinted at appearances from characters like Kung Lao and Doomsday in interviews, showing designs for one MK Vs. DC character that was planned for release, Quan Chi, first introduced in Mortal Kombat 4. The MK team lead released a render of the Mortal Kombat character via his Twitter today.
Will we ever see characters like Lobo, Quan Chi and [insert your favourite MK/DC character]added to the crossover fighter? According to Boon, "right now I don't see it happening," despite the fact that he writes those additional downloadable characters were "just about done."
With work progressing on Mortal Kombat 9 and Mortal Kombat Vs. DC Universe now eight months old, we'd guess that Midway and new owners Warner Bros. won't see the value in dedicating more resources to such a thing. Shame.
