The official Mortal Kombat Facebook page has continued the Liu Kang theme began last week with his "Shadows" theme wallpaper [full story] by posting a detailed wallpaper featuring a Mortal Kombat background, similar in style to the Mileena wallpaper from a few weeks ago [full story] in that the victim is not as detailed and serves to be silhouette. The background used for Liu Kang is the Mortal Kombat II classic The Dead Pool.
This image seems to correspond with his Shadows wallpaper, as it appears to be the same fatality only in a different stage. Judging by what we've seen it seems to be a powerful punch through the chest, perhaps an homage to the one-inch punch which powerful monks have mastered through the centuries. Here, Liu Kang is drawing back after delivering this devastating finisher to his opponent. It remains to be seen if this is perhaps one of Liu Kang's in game fatalities.
In addition, Liu Kang's section on Facebook confirms the inclusion of his famous Dragon Morph fatality with a small description, which is accompanied by a small render of Kang which may either be an alternate costume or perhaps a second player costume.
"With one gruesome bite, the typically non-violent monk Liu Kang morphs into his dragon form and decapitates his enemies, leaving a river of blood behind."
It still remains to be seen if the fatality in the wallpaper is at all connected with the classic fatality from MKII.
