Blue Devil, a comic which debuted in 1984, told the tale of Dan Cassidy, a stuntman and
Special Effects expert who was part of the crew for a monster movie. He created an amazing, full-body prosthetic devil suit chock full of
Practical Effects, and, since this was
the DC universe, a strength-enhancing exoskeleton, as well.
That's right: he created functional, battle-ready
Powered Armor, wrapped it in latex and animatronics,
and used it as a movie prop.
Naturally,
It Got Worse.
The movie was being filmed on location, in a Lost
Mayincatec Temple of Doom, and the hapless Hollywoodlanders awoke the
Sealed Evil in a Can: a demon named Nebiros.
Dan, of course, decided to fight off the demon in his
souped-up rubber costume, and managed to drive it back into the aforementioned Can, and reSeal it. In the fight, alas, he took a full-on blast from the demon's
Eye Beams — and when the dust cleared, he realized that he could no longer take it off.
It was fused to him.Because of this
weird fusion of magic and technology, Dan became a
Weirdness Magnet — in fact, this is the
Trope Namer. His comic was a funny, fun-filled romp through the superhero universe, with tongue-in-cheek side trips into the territory later staked out by Vertigo. Dan even joined the
Justice League, during the soap operatic and angst-heavy Gerard Jones run.
Needless to say,
The Nineties were
not kind to him. He made an (involuntary)
deal with a devil for increased power, and now really
is a devil.
Since then he's become a member of a team title,
Shadowpact, which has a team of magical troubleshooters including other "esoteric" DC heroes, which include Detective Chimp and Phantom Stranger, and has even joined the
Justice Society of America. His sidekick, Kid Devil, suffered a similar fate (and later joined the
Teen Titans.)
