In addition to their Mortal Kombat 9 tidbit reported on earlier, Kotaku has managed to procure several revelations made at the Comic-Con panel for Mortal Kombat vs. DC Universe! The first of these are the four playable characters promised to the fans back before E3 took place. From the Mortal Kombat side of things the Edenian princess Kitana and Special Forces agent Jax will make their presence felt. From the DC Universe, Batman's most revered enemy the Joker and another of DC's most iconic heroes, Green Lantern will enter the battle. Ed Boon also made an interesting comment about writer Jimmy Palmiotti being an unlockable character:

Boon also announced that Mr. Palmiotti himself would be squirreled away in the game as an unlockable character. He'd be very well hidden, Boon said, with a Johnny Cage-like model shown on screen.

In addition to this, another of Superman's most memorable environments, the Fortress of Solitude, has been confirmed to be in the game. Captain Marvel also appears to be in the playable version of the game at Comic Con.

Finally, we didn't have to wait long to see what the name John Tobias truly means to MKvsDCU. In the limited edition of the game will come a comic book, and that comic will be illustrated by none other than the co-creator of Mortal Kombat, John Tobias himself.
