i'm glad i'm not the only one who had that notion.

I was recently reading the book Fulgrim and then just looking at the Sslyth model I'm like "hey! it's one of the Laer!" lol

There's also the Enoulians from Dark Heresy's Creatures Anathema. The remains of a shattered alien civilisation who work as mercenaries but always against the Imperium and in recent times they are ever more often sighted side by side with the forces of Chaos…

There are a bunch of Chaos-worshipping xenos in the Gaunt's Ghosts novel Traitor General. I think it's weird that Games Workshop has never developed 'Chaos Xenos' as a troop type in the tabletop game…

I'm surprised nobody has mentioned Loxatl

Even if not as a playable race, they're a great start for minions

I was hoping to get a big dark eldar write up in the slaanesh book, same way necrons got one in the tzeentch book, possibly with rules for using them as player characters somehow. Then I found out rogue trader already had a whole dark eldar book, and kinda figured that would be a no.

Still, I'm holding out hope that after the 4 main books are done, maybe with chaos undived as well, we could get some more obscure source books, like dark mechanicus and especially chaos xenos.

I don't actually have the books but I believe Rogue Trader have some rules for playing Xenos characters, Orks, Kroot and Dark Eldar I think.

With the the corruption rules would it be possible for one of these to fall to chaos (for reaching the 100 corruption threshold) and if this was possible would it be possible to re-jig this so you could use one of these archetypes as a starting Black Crusade character?

I am surprised FFG haven't had more of a xenos flavour to their lines, with all books except BC focusing on the Imperium and even BC only having human based characters (even if you do quickly become a pretty cool mutant).

I would love to see a line come out based on the Tau Empire, there would be an enormouse potential for unique and interesting xenos races, plus pretty much any character you had before would still be an option as the Tau have plenty of human auxileries.

yeah, it's kinda strange when ya think of it, iother then the eldar/Dark eldar thing, it seems all the mainline xenos are conspicious for their LACK of interactions with chaos

I'd argue that the Necrons have fairly active (but not lively!) interactions with Chaos.
