Thanks to an image posted by CAW Evolution on Gamefaqs, it seems that Lobo will be the first DLC character in Injustice Gods Among Us. This really shouldn’t come as a surprise to anyone, since Ed Boon tweeted a picture of Lobo a month ago, which lead to rampant speculation of him being included.
Unfortunately no further information is know about Lobo, but some people have already pointed out his likeness to Kano from Mortal Kombat. In either case, it will be interesting to see how this plays out if it’s indeed true.
