Just one day for The Flash to come back, and another trailer reminds us of that… with some new footage from the first episodes. From the second episode, Flash of Two Worlds, we get a glimpse from another new villain: Eddie Slick, who’ll be portrayed by Kett Turton. In the show, he’ll be just another metahuman popping around to wreak havoc in Central City, this time with the ability to create and manipulate sand; in the comics, he is quite an obscure villain, who debuted as a Martin Stein look-alike (something that they obviously changed in the show). Anyway, let’s see what else there is to say about him.
Not much is known about Eddie Slick’s early life, apart from the fact that he had always been good in making the worst choices possible. He lived in New York City, and he was a small-time crook, a gangster-wannabe who always tried to make money the fastest way possible. He joined a group of professional criminals, some true mobsters who had quite a taste for gambling… especially when they won. In order to become good friends with them, Slick 
reinvented himself as a boxing manager, obviously doing his best to fix the competition, warning his pals which fighter they had to place their bet on. His most successful athlete was a beast of a man stage-named King Crusher, who was doing good… but not good enough. Slick drugged all his athletes as a rule, but with Crusher he decided to do something more, and when he managed to put his hands on some experimental mutagenic steroids, he treated Crusher with them. As a result, King Crusher surely became bigger and stronger, and he kept winning a match after the other… but the process wasn’t stopping, and he became strong to superhuman levels; the steroids also affected his psyche, and the wrestler went mad. In a vengeful rampage, King Crusher targeted Eddie, and the manager couldn’t do anything but run from him. Luckily enough, in NYC’s streets King Crusher saw Professor Martin Stein, who was dating Emily Rice. Coincidentally, Stein looked exactly the same as Slick, and the wrestler targeted him instead. Stein had the time to look for his young friend Ronnie Raymond and to merge with him to form the superhero Firestorm, defeating King Crusher and saving Eddie Slick in the process… but the whole illegal steroids traffic, the gambling circuit and all Slick’s affairs were exposed, thus ending the crook’s criminal career.
Eddie Slick managed to avoid prison, but that wasn’t a stroke of luck at all: his powerful friends from the mob had lost a fortune with the King Crusher affair, and they wanted to exact justice their own way. Slick was deemed responsible for the entire situation, and the gangsters decided to make an example of him: they brought him to their headquarters in Las Vegas, and they executed him by burying him alive in the Nevada Desert. The sand of the desert, however, was irradiated, and the close encounter with Firestorm had already modified Slick’s organism: instead of dying as he was supposed to, Slick was transformed into a creature entirely composed of sand, able to control other 
sand at will. Weeks spent underground had also made Slick insane, and he emerged from the desert pretty much deranged: naming himself Sand Demon, Slick returned to Las Vegas and started hunting down his former friends and employers, killing them one after the other. These murders attracted the attention of the new Firestorm (formed by Ronnie Raymond and Mikhail Arkadin), who was looking for a still MIA Martin Stein. From the news, Ronnie believed that the Sand Demon was actually Stein, and traveled to Las Vegas to try and make him “come back to his senses”. In the middle of a desert, with all that sand at disposal, Slick proved to be an extremely dangerous opponent even for Firestorm, especially considering that the latter was restraining himself believing he was facing his friend Martin Stein. When Ronnie realized the Sand Demon wasn’t Stein at all, and that he was far too powerful and too crazy to be controlled, he stopped holding back, and he used his powers to overheat Slick, turning him into glass. The Sand Demon’s body fell to the floor and shattered, thus ending the short-lived superhuman existence of Eddie Slick.
Eddie Slick is, simply put, a complete failure. Greedy, vulgar, sneaky, Slick makes the one and simple mistake of believing himself to be extremely smart, while he’s actually quite a dumb man. As the Sand Demon, he’s a remarkably powerful being, entirely made of sand (thus invulnerable to most arm) and capable of manipulating surrounding sand as well: in the Nevada Desert, he has an entire state to control, thus creating sandstorms, tornadoes and even gigantic quicksands. Just as powerful as he is crazy, Sand Demon is an extremely dangerous man, once stupid and mediocre, now stupid and lethal.
