Cryptic Crossword Clue: Pollution-loving aliens stormed so dangerously (9)
Doomsters are a race of pollution-loving aliens who are looking to make Earth a wasteland of toxic chemicals and contaminated air. Impatient creatures.
Doomsters in the Comics
Justice League of America – Issues 78 and 79
The Doomsters show up and start poisoning the Earth – turning water into oil-ridden muck and the skies into smokey filth. Luckily, the JLA is joined by Black Canary (who becomes a full member of the team, presumably as some kind of satellite-warming gift to themselves) and, uh, the Vigilante, a guy who likes to wear a cowboy costume.
Fortunately, nobody else is really needed to save the day other than Superman and Green Lantern, and after a bit of space tourism, they rapidly do so. And pollution never existed again.
