PSP ISO Download: Mortal Kombat vs DC Universe - Clash of the Titans
According to interviews, the characters were chosen for their popularity, and for parallels between them from both universes.[3] Ed Boon, creative director of Mortal Kombat vs. DC Universe and co-creator of the Mortal Kombat franchise, has said that some of the characters' abilities, especially those from the DC Universe, had been toned down to make them balanced within Mortal Kombat vs. DC Universe. For example, Boon specifically mentioned that Superman became vulnerable because of magic.[28][29] Boon revealed that two new characters were developed as downloadable content, Quan Chi from Mortal Kombat and Harley Quinn from DC comics but had been discarded.[30] He had also hinted earlier at the prospect of Kung Lao and Doomsday being downloadable characters.[31]
