The secret villain

One of the most spread theories is that the villain the Squad is sent after is Incubus, the brother of Enchantress (well, a relative of the demonic entity possessing June Moon). Apparently, Enchantress reveals her plans later on in the film, when Incubus has already arrived on Earth. But this theory is too thin.

Another one says that the Tattooed Man (played by Common) is the main baddie. In the comics, he is a villain who can manipulate the living tattoos on his body. The thing in the subway does seem to have tribal tattoos on his body. And we don’t really know what effect these living tattoos have on people. By all means, we also believe this, though we don’t know if there is some hidden relation between the Tattooed Man, Enchantress, and Rick Flag.

Lastly, there is one more theory, which is even weirder, saying that the creature in the subway is M’nagalah, the Cancer God, who can infect and enslave those with whom he comes into contact. Physically, this infection manifests itself through boils and all sorts of lesions, which appear on the skin of the victims. Could this be the reason why those soldiers fight the Suicide Squad?
