"And eat them!"
No, seriously, that's his name. Bozo the Iron Man was created by the paradoxically-named Quality Comics and debuted in 1939, 24 years before the Marvel version. A bulletproof smasher of cars, people, animals, and buildings, this Iron Man is a creepy grinning robot with the power to fly using the spinning retractable beanie on his head.
In this story, space looks exactly like upstate New York.
Bozo is created by standard-issue mad scientist Dr. Van Thorp as a doomsday machine to wreak havoc upon the world. Van Thorp believes that as long as his murderbot does his bidding with a smile, no one will suspect his evil intentions, which makes about as much sense as painting a smiley face on a brick of Semtex -- people are still going to run like hell the moment they realize what they're looking at. Fortunately for the world, Van Thorp's obligatory evil scientist soliloquy is overheard by his lab assistant, the puzzlingly well-dressed Hugh Hazzard. Hugh climbs inside the jolly grey giant and, for whatever reason, uses a handgun -- instead of, you know, the indestructible robot -- to thwart the villain.
