The next entry in the Mortal Kombat series, Mortal Kombat 11, has been announced only last week, and details on the full character roster have yet to come in. Alongside some of the most popular characters that have appeared in the series, there will apparently be a guest character who isn’t new to the world of fighting games.

A few hours ago, Todd McFarlane pretty much confirmed that Spawn will be in Mortal Kombat 11 in a Reddit AMA.
