Don't Be So Negative (Blackhawk 227)

Sacre Bleu! The Blackhawks are up against it, not only fighting a mad scientist but also a form of matter that can (checks notes) DESTROY THE ENTIRE UNIVERSE. Don't worry, they've got a 'copter and flashy red jerkins, and also Chop-Chop who is apparently a Warlock! It's all here in Blackhawk #227!
