Doom (and Gloom!)
What's with supervillains always trying to bring on the end of the world? We stopped wondering and started supplying what they needed to make it happen: one quart of 100% pure Doom. Best enjoyed with Gloom. Now, we're selling these essential products together, so you can save money while fomenting chaos in the universe.
CAUTION: as with all Brooklyn Superhero Supply Co. Superpowers, we advise a) extreme caution when opening the container (in fact, we advise against ever opening it - are you really that keen to tamper with the essential nature of our universe?) and b) we would like to make very clear that this is not an edible product. Don't put it in your eyes, on your hair, or in your favorite food.
