4176. Blue Devil

Blue Devil is a superhero featured in material published by DC Comics. He first appeared in a special insert published in Fury of Firestorm #24 (June 1984).[1] That story led directly into Blue Devil #1, also cover dated June 1984. He was created by Dan Mishkin, Gary Cohn, and Paris Cullins.

Daniel Patrick Cassidy is a special effects wizard and stuntman hired to create and play the title character in the movie Blue Devil. To that end Cassidy creates a full-body costume with a hidden powered exoskeleton and built-in special-effects devices. When two of his co-stars accidentally free a demon named Nebiros, Cassidy uses his costume to drive the demon back, but not before being blasted with mystical energy. After the fight, Cassidy finds that the blast has permanently grafted the Blue Devil costume to his body.
Cassidy quickly finds himself embroiled in repeated adventures and conflicts with supervillains, as his newfound status has turned him into a "weirdness magnet." Never stopping to seek a way to remove his costume, Cassidy starts to enjoy his new lifestyle, and becomes more and more comfortable as a superhero, even accepting a place in the Justice League of America. He gains a sidekick of some sort, when Eddie Bloomberg, his former gofer and devoted fan, designs a suit similar to his own to adventure as the Kid Devil. Eventually, he moves into "The House of Weirdness" with Cain the Caretaker as his superintendent.

Powers and abilities

Even before he became Blue Devil, Dan Cassidy was a highly trained martial artist and acrobat. His costume included Kevlar body armor, visual and auditory amplifiers, radio gear, mini-gills allowing underwater breathing, and servo-motors which increased his strength at least twentyfold. After being grafted to Cassidy's body the costume became organic and gained the ability to self-repair at an extremely fast rate (effectively a healing factor). Cassidy's abilities seem to have been changed little by his transformation into an actual demon.
In his current incarnation, Blue Devil still possesses some degree of superhuman strength, capable of going toe-to-toe with beings like Eclipso, and knocking out a power-drunk Enchantress in one punch. He is also remarkably resistant to physical damage, evidenced when Eclipso threw him a distance of approximately 500 feet upwards, he did not even require time to recover before getting up and heading back into the fight.
Originally, Blue Devil wielded a trident of his own design which included, among other things, rocket engines capable of carrying two people at high speeds. He now carries the Trident of Lucifer, which allows him to find demons on Earth and banish them to Hell. During a battle with Eclipso and the Spectre the trident was thrown into the ocean; it was recovered shortly after by Aquaman who returned it to Cassidy, and much later given to Jack of Fire.
Briefly resuming his human body with a more powerful exosuit, Cassidy is given back his trident and demonic powers by Jack of Fire, but as a "demon with a soul".
