### Reluctant Hero

Dan Cassidy was a special effects wizard and stuntman whose credits had included *The Battle of the Las Vegas Showgirls* and *Space Ninja* when he was hired by his friend, film director Marla Bloom, to create and play the title character in the Verner Bros. monster movie Blue Devil. Cassidy's specialty was somewhat unusual - rather than create optical effects that would later be applied in post-production, Cassidy specialized in "in camera" mechanical and cybernetic effects. To that end, Cassidy created a full-body costume for Blue Devil, complete with a powered exoskeleton and built-in pyrotechnic devices. Cassidy also created a rocket-powered prop trident which was, among other things, capable of flying.

During location filming on the mysterious Ile Du Diable, Wayne Tarrant, the "hero" of the film, and his co-star (and Dan Cassidy's eventual girlfriend) Sharon Scott, accidentally freed a demon named Nebiros. Though Cassidy faced incredible odds and a near-death experience, he was able to effectively use the devices built into his costume to drive the demon back to its home dimension. Unfortunately, he was blasted with demonic energy in the process. After the fight, Cassidy found that the blast had permanently grafted the Blue Devil costume to his body. Cassidy, a devout Irish Catholic, was stuck in the "skin" of an unholy Blue Devil.

While trying to find ways of escaping his costume (enlisting the help of S.T.A.R. Labs and Dr. Jenet Klyburn in the process), the newly-named Blue Devil soon found himself involved in conflicts with super villains such as Metallo and The Trickster (who eventually became an ally and friend). Nebiros, who now had an affinity for his "little brother," would return time and time again to harass the Blue Devil, and just as often Cassidy would banish him to his own dimension (often with the help of magical allies like Madame Xanadu and Zatanna). Cassidy's friend Norm Paxton, a cinematographer, theorized that the blast that had made Cassidy a Blue Devil had also turned him into a sort of "weirdness magnet." Though he initially insisted that he was no super hero, it took him little time to adapt to the realities of his existence. While he continued to seek a way to regain a normal life, Cassidy became more comfortable in the role of hero over time, and even gained an unwanted sidekick in the form of Kid Devil - actually Eddie Bloomberg, Marla Bloom's nephew.

Blue Devil would spend the next few years working with superheroes as diverse as The Creeper, Black Orchid, the Omega Men, and Superman. Later, he would also encounter Cain and Abel, who would go on to rent Blue Devil a room in the other-dimensional House of Weirdness, sister structure to the House of Mystery and House of Secrets. That house contained mystical doorways into a Malibu beach house, a house outside of Metropolis, and several other places.

### Retirement and Comeback

After joining the rest of the heroic community in fighting the Anti-Monitor during the *Crisis on Infinite Earths*, Blue Devil found that he was attracting less and less weirdness to him and his friends, and went into semi-retirement as a hero. Though his younger sister Frankie was later revealed to have been a sleeper agent of the Manhunters, Blue Devil did not publicly participate in the *Millennium* affair or any of the subsequent major events during which the superhero community banded together.

After a several-year period during which Cassidy's and Marla Bloom's careers suffered a downturn, Blue Devil resolved to help both himself and his good friend. Sensing an opportunity when the Justice League instituted an open-door membership policy (effectively granting membership to every superhero on Earth), and sponsored by the mysterious organization known as the Arcana, Blue Devil came out of retirement and joined the team in order to make a "comeback" as a celebrity. Though he was only barely tolerated by some of the more serious members of the team, Cassidy's heart was in the right place, and he embarked on a quest to increase both his powers and his fortune.

Shortly after Blue Devil joined the team, the demon Neron took control of Hell and began seeking souls on Earth. Recognizing Cassidy's sense of thwarted ambition, Neron approached him with the chance to be a movie star, which the latter eagerly accepted. Cassidy had no way of knowing, however, that the true cost of his bargain would be the death of his close friend Marla Bloom. After performing the seemingly innocuous task of destroying an automatic electrical substation far in the desert, a chain of events was set in motion that would result in Bloom and her pilot dying in a helicopter accident. Blue Devil got his wish - sympathetic movie offers began to pour in - but the price was too high.

Guilt-ridden, Cassidy made the ultimate heroic sacrifice: he cheated Neron of his soul, but died in the process. Soon after, he was reincarnated as an actual demon, with an increase in power.

### Demonic Existence

After the JLA disbanded and reformed again, this time with an invitation-only membership, Cassidy found himself without a team. Having long before lost the companionship of his movie-studio friends, he joined a new "Justice League of France" consisting of himself, Firestorm, the second Amazing Man, the surviving Crimson Fox, and a woman who claimed to be Icemaiden. Unfortunately, the latter was in fact the villainous Nash in disguise, and she killed nearly all of her erstwhile teammates. Again, the Blue Devil was destroyed (reduced to ashes and bone by concentrated holy water), and again, he was restored to life, this time by the magician Faust, who used the Devil's bones to reanimate him. Facing Nebiros for the last time, Cassidy was granted the demon's Trident of Satan. Controlled by Faust, Blue Devil joined the Sentinels of Magic, where he worked alongside Ragman and Enchantress among other supernaturally powered beings. He was finally freed from his obligation to the team when Faust restored his last bone to him - however, Blue Devil soon lost his life a third time while fighting Hermes Trismegistus.

### The Shadowpact

The Blue Devil did not remain dead long, however, and was soon seen roaming the Earth and banishing demons back to Hell. Cassidy began working as a bouncer at the Oblivion Bar, working for Nightmaster. There, he joined with Ragman and Enchantress once again, as well as Nightshade and Detective Chimp, in battle against the Spectre, who had declared war on all magic. He soon became the strong-man of the newly-dubbed Shadowpact, able even to wound Eclipso, and has since decided to stay with the team. He now helps his new teammates to contain the wild magic set free by the Spectre's actions.

Shortly after the *Infinite Crisis*, Blue Devil and his teammates were trapped inside a "blood shield" that grew over the town of Riverrock, Wyoming. While inside the town, Cassidy met a member of magic-based villain group called the Pentacle named Jack of Fire. Jack, who wore a bandana over his mouth and wielded pyrokinetic abilities, claimed that he was Cassidy's brother, and that Cassidy's deal with Neron had cursed the entire Cassidy family to Hell. In addition to becoming demonic himself, Jack claimed that Blue Devil's late parents had been pulled out of Heaven, and that his "sisters" Mary and Frances were also cursed. The veracity of these claims is questionable - though Cassidy does have a sister, Mary Frances, he had never before mentioned a brother or another sister. Oddly, Blue Devil claimed to have no recollection of having any siblings at all - a mystery that has yet to be solved.

One day, Blue Devil's former sidekick Eddie Bloomberg, now a true demon himself, came to Cassidy inquiring about his aunt Marla's death. Blue Devil admitted that he had not been honest with Eddie regarding the circumstances of her demise, and the teen responded hastily in shock. Before he could explain the truth to Eddie, Cassidy was told by his former sidekick to stay far away.

Cassidy then found himself under threat by the former Justice League member Zauriel. Because of Blue Devil's popularity as a demon, he had unknowingly given hell and demons a better image, prompting others to make their own deals with demons. As a result, Zauriel was tasked with killing Blue Devil and doing away with his bad influence on the populace. However, when Zauriel realized that Blue Devil wanted nothing more than to combat hell, Zauriel agreed to give him some time to repair his mistakes. Blue Devil is currently in hell bargaining for his soul with a lawyer. After 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".

His most recent appearance was with Zatanna and the Phantom Stranger at the desecrated grave of Batman in Blackest Night. In typical fashion, he cracks that the Stranger brought them there to "hold hands and sing Kumbaya." That changes when black rings take control of Crispus Allen. While Zatanna was sent to gather the Justice League, Blue Devil and the Stranger attempt to stop the Black Lantern Spectre, failing miserably. He and the Stranger head to Nanda Parbat, where the Stranger helps Deadman remove the black ring from his body. Blue Devil is then tasked by the Stranger to protect the body, being told that it is of "singular importance".

### Weaknesses

* **Weirdness Magnet:** After being fused into the Blue Devil suit, Norm theorised that Dan's fusion of science and magic made him a "weirdness magnet" that attracted abnormal activity to him. This was dismissed as a joke until until Dr. Kylburn had the statisticians at S.T.A.R. Labs substantiate the claims. They even gave him money to put his uncanny probability to the test in Las Vegas. The theory became conclusive upon meeting Cain, who confirmed the existence of such a concept, even pinpointing the positively charged force radiating from his abdomen. It's unknown if this phenomenon was caused by the magic of Nebiros or Danny's family history which has faerie blood on his uncle Seamus' side.
* **Technological Reliability:** Although the suit was organically grafted to Danny, it was still mechanical in nature and vulnerable to being hijacked by the the correct frequency. His former friend and fellow stuntman Larry Bolatnsky managed to remotely control Blue Devil to fight Firestorm.
