Edward is 5' 8" with blond hair and blue eyes. Anita describes Edward as "not an imposing man", appearance-wise. She also describes his eyes - "as cold and as distant as wintery skies". A hitman, he now specializes in assassinating supernatural targets, because humans were too easy. He particularly hunts vampires and lycanthropes, and taught Anita most of her combat skills. Anita considers herself to be possibly Edward's only true friend.
Edward is an extremely dangerous man, as Anita describes him. He is known to the monsters as Death, seemingly because he has had so many kills. In point of fact, he, along with Anita, Bernardo Spotted Horse, and Otto Jeffries/Olaf, comprise the group of vampire executioners known to the vampires as The Four Horsemen. He is Death to Anita's War, Bernardo's Hunger, and Olaf's Pestilence.
Edward's past is shrouded in mystery, however we do know that he once worked and was trained by a man named Van Cleef, with the suggestion of a military connection. He is recognized by others who trained under Van Cleef who call him "The Undertaker" a name he apparently acquired due to having the highest kill count of any of Van Cleef's trainees. Edward tells Anita that he was allowed to leave on Van Cleef's troop on the condition that he never spoke about it.
According to Anita's account in Guilty Pleasures, approximately two years before the start of the series, Edward and Anita collaborated in the hunt for Valentine and his nest of vampires. Ultimately, Edward used a flamethrower, burning a house down around himself and Anita. This story is told in a 2 issue comic book "The First Death".
Edward is a sociopath alongside Anita. Sociopathy plays a big part in the series. Between Anita and Edward's relationships, they often talk about how effortlessly they can kill, without feeling anything, without caring for the ones they kill. Another topic that they openly discuss, have discussed, many times, is "who would be better". Edward says that his greatest fantasy is to go against Anita, and see who is better. Edward claims to have dreamed about it. Anita can see the excitement in his eyes and believes him. Edward acts like he doesn't really care about anything, but we see in Obsidian Butterfly he shoots through a whole gang of baddies, to save his girlfriend Donna's children, Becca and Peter. "I always thought Edward killed emotionless, his eyes cold." Anita said, in Obsidian Butterfly, "But when I looked into his baby blues, they were filled with fire. I had always thought Edward was scariest at his most cold. I was wrong. Edward the family man was downright terrifying."
Edward leads a double life; Edward as an assassin is the true Edward (as far as we know). He has an alias, his only legal identity (as far as we know) called Ted Forrester. Ted is a licensed bounty hunter, and "good ol' boy" operating out of Santa Fe; like Anita, he becomes "grandfathered" in as a Federal Marshall. Ted is engaged to a widow, Donna Parnell, with two kids, Peter and Becca (aged 14 and 6 in Obsidian Butterfly), not to mention the two maltese Peeka and Boo. He appears to have a close relationship with them, and Anita almost thinks that Edward could be in love. However, in The Harlequin, it is clear that Donna and Becca do not know "Edward", only "Ted". Anita is surprised to learn that Peter knows "Edward" - and wants to follow in Edward's and Anita's footsteps.
In Skin Trade, Edward under the guise of Ted Forrester comes to Las Vegas to help Anita hunt for the vampire serial killer Vittorio. He brings with him Olaf and Bernardo. Edward acts a little like a boyfriend to Anita to keep Olaf at bay, since no one else that Anita dates or loves is dominant enough. Yet Anita says she could never feed off Edward in any way because it would be like doing a family member. Edward admits to have been contacted as Death to take out the Mother of All Darkness and he turned down the contract. The price was right, but he admits that he has commitments now, his alter-ego Ted has people who love him and Edward would prefer to return home to them than to fight something potentially more dangerous than he is.
In Hit List, Edward reveals to Anita that Theodore 'Ted' Forrester is indeed his original name and is the name he went in the Military with. This was done to comfort her since she was still upset about killing Haven. He also tells her that he himself has been forced to kill a lover, though he didn't love her.
Edward is a deadly fighter, and expert with multiple varieties of weapons, from knives to small caliber firearms, through rifles and up to flamethrowers. He is also a skilled lock pick, and has contacts who can get him illegal weapons at short notice. He has the chameleon like ability to blend into situations and adopt many disguises.
Edward is a gun freak, knowing a lot about every brand of gun. He commonly carries multiple firearms and knives concealed about his person, and more if he expected to fight; Anita saying that, "He carries more firepower than Rambo". He has given Anita several "toys" (as he calls his weapons), at various times including a Mini-Uzi and a sawed-off shotgun, a derringer that 'kicks like a son-of-a-bitch', and she was envious of his custom Seecamp auto. He uses any sort of firepower, regardless of any innocent bystanders. Edward has been known to use a flamethrower on vampires. He also customizes his bullets, filling the silver hollow points with holy water and mercury, sealed with wax. He also carries vials of silver-nitrate, which can be be injected into sleeping vampires to kill them swiftly and noiselessly.
