Justice League of America #79

Justice League of America #79 (On Sale: January 27, 1970) has a nice cover by Neal Adams.

This issue has the book-length by "Come Slowly Death, Come Slyly" by Denny O'Neil, Dick Dillin and Joe Giella. Continuing from last issue, we have Superman and Green Lantern on the desolate planet Monsan seeking a clue to the identity of the Doomsters, while Green Arrow is being forcibly removed from the office of the Star City City manager and Batman, Atom, Black Canary and the Vigilante are being slowly lowered into a vat of something pretty vile. As luck would have it though the two guards escorting Green Arrow are not cops and don't particularly like the City Manager, so they let Green Arrow go.

Racing back to the Doomsters' plant he gets there just in time to jam the machinery lowering his pals into the vat of icky stuff. He revives his teammates just in time to take on a cadre of Doomsters who, when overwhelmed by the JLA, lock themselves into the inner workings of the plant. That ends up being a disguised rocket that the Doomsters use to blast away from the JLA.

Meanwhile on Monsan, Superman and Green Lantern find a survivor who with his dying breath tells the tale of one of their leaders, Chokh, who when the industrial might of the planet so fouled the air came up with a way of altering Monsan physiology so that they could breathe polluted air and thrive of poisoned water. But the alteration not only modified their bodies, it warped their minds, turning them into Doomsters, who want nothing more than to spread the pollution of Monsan to other worlds.

back on earth, Batman radios Hawkman in the JLA satellite and tells him he must stop the alien spaceship above Star City. Using his Thangarian space cruiser, Hawkman is going to use a gravity beam on the flying building when it explodes exposing the sleek battleship hidden inside. The Doomsters jam Hawkman's controls forcing him to abandon his ship which they then blast in half. Realizing the the Earth people are more threatening than they thought the Doomsters drop pollution canisters all around the globe and then send out a warning message to the people of Earth that they have one hour to make peace with themselves, before they are inundated with "total pollution."

The JLA assemble in their satellite just as the returning Superman and Green lantern recover the wounded Hawkman. Once he is safely in the JLA satellite Superman and green Lantern begin a full attack on the Doomsters' spaceship, defeating the aliens. However, Chokh escapes and penetrates the JLA satellite where he captures Black Canary. Batman and Green Arrow try to stall him by telling Black Canary how much they appreciate her and Green Arrow even says that he may be in love with her.

Chokh is finally defeated by the Atom and later Arrow tells Canary that he meant what he said, but she says she is not ready for a new relationship just yet, but is happy that they saved the Earth. Arrow looks at the soot and ash spewing from some plants in the background and says, "Did we? I wonder..."
