[ OT ] Recurring Character

I personally love this idea, so I created multiple characters. Five, in fact. Feel free to offer name suggestions that are better than mine, or character tweaks that you think would be improvements. 
 
 _____________________________ 
 
 First, two comedic characters: 
 
 * **Olaf Gustaufson**: Tall, muscular but bumbling, dark hair, dark eyes. Dresses like a lumberjack ( plaid shirt, worn jeans, work boots ) and is probably from somewhere in Eastern Europe, or maybe Russia. A character who, no matter how hard he tries, always seems to get things wrong. It's his curse. He's stupid, but lovable. He always tries to help when he should n't because he is extremely compassionate. He tries his best to solve problems that are obviously out of reach of his somewhat lacking intelligence. Often, his incompetent grasp of the English language creates further obstacles for him. 
 
 * **Sarah Beth Fowler**: Blonde, blue eyes, attractive figure, slightly above average height, dresses classily ( dresses, business suits, etc. ). An extremely beautiful, but also extremely socially awkward lady. She always says the absolute worst things when guys try to flirt with her, but her good looks reel them in anyway. She's entirely oblivious to social cues. Her dream is to become a famous artist, but for now she lives in her studio apartment alone with her cat, Flibbertigibbet. 
 
 Now, two darker characters: 
 
 * **Roxanne Belle**: A brunette bombshell with an attractive figure that she certainly knows how to show off. A nymphomaniac with a violent streak, a femme fatale. She lures in her victims with her allure, and then murders them. She's also fond of recreational drugs, as a casual user. 
 
 * **John Smith**: His extremely average name translates over to his looks: average build, average face, dark brown hair that is somewhat balding, glasses. He constantly appears to be flustered or bewildered. Which makes sense, because he's an overworked man in a failing marriage. His marriage is failing because his wife is inattentive and cold, and because he spends too much time at work trying to ensure that his kids can live a decent life. Both he and his wife keep their young kids insulated from the reality of their parent's relationship. 
 
 And finally, someone who ca n't be labelled: 
 
 * **The Wild Card: ** This character's real name is unknown. A character shrouded in mystery. No one knows who this character is, or their origins. This person is so shrouded in mystery no one even knows what gender they are. They do shady things in the middle of the night, and are never seen without their trademark black hoodie ( hood always up ), tinted sunglasses, tattered jeans, well-worn but sturdy black boots, and, of course, black leather motorcycle gloves. Are they good? Are they evil? Are they even human? No one quite knows.
