The image taken is from the official achievement list, which is used for the achievement Brutal End, which unlocks after performing a Brutality. Thus, it seems likely that the image depicts Erron’s brutality.
A second achievement image also has Erron in it, this time for Can’t Stop This: the achievement for winning an Invasion 1v1 match.
The original story is below.
It seems that a certain gunslinger is going to make his way to Mortal Kombat X, but he isn’t going to strike many players as familiar.
Erron Black, one of the characters in the newest Mortal Kombat comic, has been seen in a screenshot supposedly from MK X. Here, he seems to be shooting Cassie Cage, a newcomer in the Mortal Kombat universe. The image was supplied by NeoGAF user Miles X.
People have been speculating that this character would be making his mark in MK X since he is a major piece of the Mortal Kombat comic story.
I like seeing what Mortal Kombat X has up its sleeve. Erron Black looks to be one of the more interesting characters in the franchise, and after Johnny Cage was announced, all we need is for Smoke, Liu Kang and Spawn to be confirmed.
