What would drive a Lantern to abandon the ways of willpower for pure rage? We’re not sure, but we’re curious to find out. So, we asked GREEN LANTERN CORPS Editor Adam Schlagman to give us some info. And he was kind enough to throw in some art. So, take it away, Adam:

What could turn the most bad ass Green Lantern into a crimson spewing red one? Find out in Green Lantern Corps #42 (on-sale November 11th) as Guy Gardner experiences a tragedy so utterly terrible that he loses complete control in Green Lantern Corps #43 (December on-sale) leading to his selection by a red ring of rage. Welcome to the Red Lantern Corps, Guy Gardner!

In the meantime, wet your appetite with this awesome design by Green Lantern Corps artist Pat Gleason then pick up Green Lantern Corps #42 on Wednesday to witness the shocking ending that only writer Peter J. Tomasi could tell.

Lots of fun stuff going on around the web, so let’s hop to it, shall we?

• The gang at MTV SPLASH PAGE have an interview with BATGIRL writer Bryan Q. Miller discussing the first few issues of the series, with preview pages from BATGIRL #4. Worth a read.

• IGN previews pages from GREEN LANTERN CORPS #42. Stay tuned for more on that issue and #43 later today right here on The Source.

• NEWSARAMA’s got their latest installment of 10 Questions Plus One Answer with our very own Dan DiDio, and Dan gives some interesting teases about what’s in store for some key characters in 2010.

• And, in case you missed it, culture and entertainment site POP MATTERS has a lengthy and engaging essay on writer Grant Morrison’s run on BATMAN AND ROBIN. Perfect lunch break reading material.

Peter Tomasi and Patrick Gleason pull out all the stops for GREEN LANTERN CORPS #40, as BLACKEST NIGHT continues and the battle on Oa rages on. The honored, fallen Corps members and the recently deceased Sciencell convicts are now bloodthirsty Black Lanterns — and they won’t rest until the bloody hearts and minds of the GLs are literally in their hands. Can John Stewart, Guy Gardner and Kyle Rayner stop the Blackest Night from engulfing Sector Zero? We’re not sure, honestly. But these three pages should get you stoked.

GREEN LANTERN CORPS #40 hits 9/2.

Greetings, Source-erers,

Michael Siglain here. For those of you who don’t know me, I’m one of the editors here at DC. More specifically, I’m one of the Bat-editors, and am currently responsible for Detective Comics, Outsiders, Batgirl, Vigilante and Booster Gold, among other comic book greatness. I’m here today to give you a peek behind the editorial iron curtain, so get ready to feast your eyes…

First up, I’d like to take a moment to congratulate the crew of Detective Comics. The lead story—by the brilliant team of Greg Rucka, J.H. Williams III, and Dave Stewart—tells the tale of Batwoman, while in the co-feature, Mr. Rucka teams up with artist extraordinaire Cully Hamner to answer The Question. As you may have heard, we’ve just sold out of Detective Comics #854 and are going back to press with a brand new cover.

But you might not have seen the uncolored version of our groovy second printing cover, so take a gander…

Pretty, ain’t it? If any of you haven’t read this issue yet, run—don’t walk—to your local comic shop and reserve your copy now. And just wait until you read Detective Comics #855, which is in stores at the end of this month. Things go from bad to worse for our heroines, but the writing and the art only gets better and better. Trust me, you definitely don’t want to miss this one.

And speaking of cool bat-related books, here’s a page from Outsiders #21, which features an all-new story arc written by Wizard Top Ten Writer Peter Tomasi—seriously, he’s number seven with a bullet—of Nightwing and Green Lantern Corps fame, with art by the amazingly talented Fernando Pasarin—of Justice Society of America fame (he’s not on the Wizard list yet, but he’s number one on the list of Top Ten Artists Who Live in Spain and Currently Work for Mike Siglain). These fine folks have crafted a tale of terror that pits the Outsiders against some of Batman’s most dangerous and vile villains. In “The Hunting” Part I, Black Lightning and Owlman head north in an attempt to track down the murderous Mr. Freeze. Again, take a look:

That’s all for now, gang. But check back soon for another update featuring the all-new Batgirl, the same ol’ Booster, the return of Doug Moench and Kelley Jones, and a top secret, unbelievably creepy Sam Kieth project.

Until next time, try to enjoy the daylight…

M.

Well, of course we had to end with the Black Lanterns. And, as you’ve probably noticed, IGN has a first look at the amazing piece of work by artist Doug Mahnke, which gives us a first look at the Black Lanterns and some of their potential members.

And in case you missed it, here’s a collection of our entire CORPS 101 series, from Green to Black. Why waste valuable time linking back when we can show it all in one place? That’s my logic, and I’m sticking to it.

What’s love got to do with it? A lot, actually.

The Guardians of Oa have the Green Lanterns while their counterparts, the Zamarons — fueled by emotions, unlike the Guardians — created the Star Sapphires, a group of super-powered soldiers wielding the power of love.

Click below for more info on the Star Sapphires, in this, our penultimate “Corps 101.” Can you guess which comes last?

“The universe has yet to discover the existence of the Indigo Tribe.”

Now you have.

What happens when two Guardians of the Universe go rogue and get all “emotional”? Well, the hopeful Blue Lanterns, that’s what. Formed by Ganthet and Sayd after they were banished from the Guardians, the Blue Lanterns always look on the bright side, even when that brightness is coming from a yellow Sinestro Corps ring. Click below to find out more.

FDR once said there’s nothing to fear but fear itself.

Well, fear is pretty darn scary. Especially if we’re talking about the SINESTRO CORPS, the evil, frightening opposite number to our heroes wearing the green rings. Taking point is, fittingly, Sinestro, Hal Jordan’s former mentor and a former Green Lantern. But he’s not the only one wielding the yellow power. You’ve seen the Green, Red and Orange. Click below to learn more about Sinestro’s gang, presented in frightening detail by the very talented Doug Mahnke.

If you dare, that is.

If I were an Orange Lantern, I’d probably go around grabbing as many other blogs as possible. That’s avarice, isn’t it? An insatiable desire for wealth. And avarice is what drives Agent Orange and his gang, so much so that they’ve foregone a wordy oath and summed up what their goals, needs and hopes are with one word:

MINE.

So, enjoy this, our third “Corps 101″ installment, before Agent Orange tries to swipe it for himself.
