So...I think its late enough in the day, and I really want to talk about what happened. So I'm going to put a giant spoil box that people can avoid just seeing it.

So the reveal is that Nemesis is not the main big bad. He's still a menace but he's not the head honcho. But someone we've seen for a long time by Miller is.
While we see Nemesis get his personal revenge, its his special mission for his master with the horns that gets us into Big Game. Because while the rest of the series has been relatively grounded, minus the nuke and some antics, its on his mission that he runs into a character named Black Lotus who references powers, super weapons, and magic, which have not been seen so far. And its after he succeeds in his mission we get the reveal...the Utopians ripped cape.
And then the mask comes off, literally, with the master in the demon mask being an older Wesley Gibson from Wanted and who proceeds to repeat the old adage of the world changed by villains, and then accepts Nemesis into the Fraternity for his success. It then flips in the end of the book with the first issue cover reveal with Wesley in full killer gear surrounded by the Fraternity with Nemesis included, surrounded by the props of series from Kick-ass, Hitgirl, Chrononauts, Huck, Night Club, the Magic Order, and possibly Starlight (may have been Superior's belt). And we also know the Ambassadors and Kingsmen are involved.
Meaning we are seeing a comic about a secret society of supervillains who killed the worlds heroes facing off against new heroes and other secret societies. This is going to be a lot more crazy then we thought.
