Possible; not possible?
This blog talks thoroughly about a "what if..." about if DC nation made shorts about Mortal Kombat. For marketing reasons or just for the hell of it. What would you like to see for an MK short?
As a side bonus:
How come Warner Bros. has not made any Mortal Kombat references lately? If one were to think, because of WB's buyout on NR (which is considered the past now) you'd wonder if WB would cash-in on this in some way. Like a guest star (as in a comic or TV show), MK short as said above, or even a reference to it on their latest shows.
Feel free to ponder on this and if you want, you may describe how you would like for such a reference to occur.
