Update later today, but since I have a creeping feeling that there's going to be times when I have to post WildCATs and other titles to help keep the World's End clear to you, and that I'm going to have to explain this whole Daemonite/Kheran thing (the reptilian scientist in Number of the Beast was a Daemonite), it's capefaggotry time! This time, about the WildCATs, the former number on team for WildStorm until Warren Ellis' StormWatch (and later The Authority) took over. Also, what makes WildCATs special is that they were part of the whole "everything turned out better than expected" turning point of 90's comics, which was due to the fact that Alan Moore took over the title for a considerable length of time and made considerable revisions.
Now anyway, to capefaggotry!
So, the first basic idea of WildStorm universe is that ever since ancient Egypt, Earth (a backwater with barely any contact from anyone in its history prior to the 20th century) has served as a battleground for the secretly waged war between the Daemonite and Kherubim (or Kheran) empires, each of whom had a detachment stranded there during around 3000 BC. The WildCATs were a team primarily composed of descendants of the Kheran detachment (one member is a human-daemonite hybrid, and one of them is a Kheran battle-android), formed by the Kheran general Lord Emp (that short guy with the cigar that called himself Baxter you've seen a couple of times over the LRs) to fight Daemonites.
Well, Alan Moore added a twist to this by having WildCATs actually go to Khera, where the revelation was that the war between Khera and Daemon has been over for centuries after total victory to Kherans and Earth was just so remote that no one bothered to relay the message. Similarly, turns out the Kherans are just as big of bastards as the Daemonites on Earth, with them being invaders to the planet they've renamed Khera where they've enslaved the indigenous species, and crippled Daemon by executing almost their entire nobility after which enforcing war reparations that drove Daemon to starvation and civil war. And of course, later Dan Abnett/Andy Lanning duo's Majestic mini-series would reveal that Kherans had intentions of doing the same to Earth as they did to their previous homeworld, with more vigor after learning that Kherans can produce fertile offspring with the natives (Kherans, being virtually immortal, reproduce extremely slowly among themselves and their female fertility rates are extremely low).
So anyway, the important follow-up of the reveal is that Lord Emp was completely disillusioned with Khera and basically withdrew from everything, and Majestic also turned his back on Khera in the end (Majestic is the Superman type in red-white costume you saw previously, and the peak of Kheran evolution), WildCATs stopped working in Kheran interests (with the occasional exception of Zealot, but she's a total bitch anyway), etc. It also lead to Spartan (the guy you saw in Coup De'tat with the white suit) to turning Lord Emp's front for the WildCATs, the Halo Corporation, into a legitimate business in the interests of using capitalism to improve the world (WildCATs 3.0 is pretty sweet btw).
