Character Name: Anthony J. Crowley
Fandom: Good Omens
Original or Alternate Universe: Alternate, being massively post-canon
Canon Point: Current Day, three years after the New Year's Resolutions came out
Species: Demon
Age: Somewhat older than 6000; looks to be in his mid to late twenties
Appearance: Crowley appears as a good-looking young man with dark hair and good cheekbones. He's almost always wearing a dark pair of sunglasses, which hide the fact that his eyes are yellow with vertical slitted pupils, much like a snake's. He smiles a lot like a snake too, and doesn't blink much. Most of the time he wears either a suit of some variety or at least very well-made tailored clothes. As an angel, size, shape and those sorts of things are somewhat irrelevant--he can change them at will. He is also able to change his shape to darker, more horrifying kinds of things, but he doesn't much like doing that. He's afraid one of these times it's going to stick.
Background:
tl;dr here and here
Reality Description:
Crowley...is from Earth. Present day, right-now Earth, as a matter of fact. He tends to work all over England (and has been, throughout history, all over the world), but on most occasions these days he can be found in London. He owns a stylish and exceedingly expensive flat in the Mayfair district, furnished all in white with cutting edge, trendy furniture and not much else. It's a rather minimalist space, tres chic in Crowley's opinion. The stereo system is slim, black, and isn't hooked to speakers but nonetheless produces top-notch sound quality. There's an original daVinci sketch on one of the walls and a set of beautiful, green houseplants, but not much else in the way of decoration. The fridge is always stocked with gourmet foods which are never spoiled, but hasn't been plugged in since he purchased it.
The major difference between the Good Omens world and our own world is the presence of angels and demons. Those kinds of beings usually try to blend in with the mortals though, or at least make themselves scarce, so to the typical observer it would literally just be regular old Earth.
Aziraphale's dusty bookshop in Soho would be another likely spot to find Crowley at any given point, as he usually hangs around and pesters the angel. The back room is a good place to chat about business or get drunk if the occasion calls for it. They're also fond of both the Ritz and St. James Park, where they often meet to feed the ducks and discuss business.
Powers/Abilities:
Oh lord. Crowley has a rather extensive list of abilities.... Most of his powers are used in canon for minor, quirky sorts of things that make his life easier. In fact, on most occasions he's perfectly willing to let things happen as they will and uses his abilities to just sort of nudge things in the right direction. For convenience's sake I'm just going to do this in list fashion:
Flight: Crowley has black, feathered wings that sprout from his shoulder blades when he wishes; most times they are hidden. It's implied that he can actually fly, though never explicitly shown.
Seeing in the dark
Purging the alcohol from his system with just a thought
Scaring non-sentient lifeforms into doing his bidding (helpful for keeping his plants green)
Glaring at things to make them stop being on fire
Keep the fridge in his flat stocked with food that never spoils, despite the fridge not being plugged in
Fireproof
Similarly, can set fire to objects with a thought or a sharp glance
Doesn't need to breathe/eat/sleep, though he usually prefers to do all three
Can bring small beings back from death, such as doves carelessly left in the coats of angels
Can also banish people/objects to unknown parts of the world/universe; it's best not to worry about where they end up
Has considered conjuring a hurricane to rid himself of a group of nannies; later settled for a workers' strike instead
Minor reality manipulation: Crowley can arrange matters so that no one gets in the way of his speeding car, and on at least one occasion assured the "miraculous" escapes of a bunch of nutters with guns Will not work in Cicero
Can fix minor scratches and dings on his Bentley with a glare, as well as turn things such as lights and televisions off or on with just a gesture
Can abandon his physical body to travel at phenomenal speed; has no real limitations on his size/shape; can assume terrible, nightmarish forms to scare the living Christ out of people
Often wishes clothing into being--he's not much for doing his own laundry
Can make the no-parking lines on a curb disappear when he wants to park there
Can use complex demonic hand signs to turn a car's engine into something unspeakable
Is able to stand in the rain without getting wet
Drives without gas, and sometimes without actually using the steering wheel or even paying attention to what he's doing
Can hold the flaming wreckage of his Bentley together with nothing but force of will--and then proceed to drive it for thirty miles or so
Has the ability to force something into being, simply by assuming that it exists (like a tape-deck in a car)
Can hypnotize and fiddle with the memories of normal humans with just a snap of his fingers
Is able to sense a person's desires--comes in handy for temptation
It's also stated that Crowley sometimes fills in for Aziraphale as a professional courtesy, and as part of the Arrangement, so he's able to do typically angelic types of things if he has to; one would assume that this means he's able to do most of what Aziraphale can do, such as healing, producing light, and possessing those with an occult inclination
He is also, of course, immortal (though his physical body isn't death-proof)
[It probably goes without saying, but a lot of these sorts of powers can be used for other things-I've only given the canon presentation of the power. A little imagination and the correct application of a miracle means Crowley can do quite a bit. He's pretty hax >>;]
