13 Angel/Angelus
Played By David Boreanaz
In Buffy: Angel features in the first three seasons of Buffy the Vampire Slayer as Buffy's main love interest. He's introduced as a vampire with a soul who seeks to do good to make up for all the lives he's previously taken. Flashback episodes reveal that before he was a vampire, Angel was an 18th-century Irishman named Liam. Prior to being cursed by gypsies with a soul, Angel (or Angelus) was one of the most evil and feared vampires to have ever existed.
Angel's soul can be taken away from him once he experiences a moment of pure happiness. This happens in the show's second season, when Angel gets intimate with Buffy. With his soul gone, Angel reverts to Angelus and begins causing havoc in Sunnydale, forcing Buffy to send him to a Hell dimension. In season 3, he returns as Angel, before leaving Sunnydale for L.A. Angel makes a number of sporadic appearances throughout the rest of the show's run.

Angel might be one of Buffy's great loves, but he never appears on one season of Buffy The Vampire Slayer thanks to real-world legal drama.

12 Cordelia Chase
Played By Charisma Carpenter
In Buffy: Cordelia Chase is the "it girl" of Sunnydale High. She's popular, vain, self-absorbed, and treats Buffy and her friends like they are pieces of dirt. However, across Buffy's first three seasons, Cordelia mellows into a nicer person and eventually becomes a friend and ally of the Scooby Gang. Following graduation and the destruction of Sunnydale High, Cordelia, like Angel, moves to Los Angeles.
Cordelia receives visions from the Powers That Be that help Angel and co to save people in need, which helps her character to move further away from the self-absorbed cheerleader she once was.

11 Wesley Wyndam-Pryce
Played By Alexis Denisof

A member of the watcher's council, it is his job to train the new vampire slayer, Faith, whose powers were activated following Buffy's temporary death at the end of season 1. Wesley is a posh, bumbling, scaredy-cat who likes to think of himself as tough, when, in reality, he is afraid of his own shadow. Wesley also engages in an inappropriate romance with Cordelia.
In Angel: Wesley s the main cast of Angel part-way through its first season. When he first arrives in L.A., he is the same irritating buffoon who was last seen during the climax of Buffy season 3.

10 Spike
Played By James Marsters
In Buffy: Known for his platinum blonde hair, his fondness for leather coats, and his sarcastic humor, Spike is one of the Buffyverse's most popular characters. Following his debut in the Buffy episode, "School Hard", Spike went on to be the Big Bad (along with Angelus and Drusilla) for the show's second season. A vampire, Spike was once a failed Victorian-era poet named William Pratt. After becoming a vampire, he gained the nickname "Spike" because of his habit of torturing his victims with railroad spikes. Spike is the only vampire who has ever killed two slayers.
Spike makes a one-off appearance in Buffy season 3, before ing the main cast from the fourth season onward. When a chip is put in Spike's brain that prevents him from being able to hurt humans, he turns to killing fellow demons instead and slowly becomes an ally to the Scooby Gang.

In the show's final episode, Spike saves the world by sacrificing himself, demonstrating that he's capable of being a hero.
Spike is the only character to share scenes with every other main character in the Buffyverse.
In Angel: Following an appearance in a season one episode that ran parallel with Buffy season 4, Spike s the main cast of Angel in the show's final year.

At graduation, Harmony is one of several students who get turned into a vampire. In seasons 4 and 5, she makes several attempts to be Buffy's arch-nemesis, but is too clumsy and incompetent to pull it off. Harmony also engages in a sexual relationship with Spike, who cannot stand to be around her.
In Angel: Harmony makes her first appearance in Angel during the season 2 episode, "Disharmony". At first, she doesn't reveal to Cordelia that she is now a vampire, before later betraying her and the rest of the gang by leading them to a cult of vampires.

Harmony is the last character to Angel's main cast, appearing in the opening credits from the season 5 episode, "Underneath".

7 Harsh Realities About Angel’s Character In Buffy The Vampire Slayer
Forever grappling with his dark past and tormented soul, Angel from Buffy the Vampire Slayer is a complex character who is not without fault.
8 Buffy Summers
Played By Sarah Michelle Gellar

Having recently learned that she is a slayer, Buffy soon becomes acquainted with her Watcher, Giles, who teaches her everything she needs to know about her new responsibility.

By the show's final episode, she has amassed a whole army of allies willing to help her, and she learns that she doesn't need to face her responsibility alone.
Across the seven seasons of Buffy the Vampire Slayer, Buffy's main emotional arc is that she feels alone. For the most part, she is the only slayer and no one else understands what carrying such a burden is like. She wants desperately to have a normal life, but her duty as a slayer prevents it. By the show's final episode, she has amassed a whole army of allies willing to help her, and she learns that she doesn't need to face her responsibility alone.
In Angel: Buffy makes two one-off appearances in the first season of Angel. In the episode "I Will You", Angel is temporarily made human again, meaning he and Buffy can resume their relationship, only for Angel to realize how useless he is in human form.

7 Daniel "Oz" Osbourne
Played By Seth Green
In Buffy: Oz appears as a recurring character throughout Buffy's second season, before ing the main cast in season 3.

In Angel: Outside of Angel's main cast, Oz is one of the first Buffy characters to cross over to the spin-off show.

Following this, Oz makes no further appearances on the show.
6 Willow Rosenberg
Played By Alyson Hannigan
In Buffy: One of Buffy's best friends, Willow starts off as a dorky and socially awkward high school nerd with an above-average intelligence. She soon becomes a key member of the Scooby Gang and a secret weapon in Buffy's fight against evil. As the series progresses, Willow gets increasingly involved with magic, eventually becoming a powerful witch.
Another one of Willow's main storylines sees her entering into a romantic relationship with another woman, Tara. At the time of the show's initial broadcast, Willow was one of the few lesbian characters on TV. In the sixth season of Buffy, Willow becomes consumed by magic following the death of Tara and goes on a blood-filled rampage. Fortunately, season 7 sees her returning to her normal goofy self.
Willow is the only other character besides Buffy to appear in all 144 episodes of Buffy the Vampire Slayer.

5 Darla
Played By Julie Benz
In Buffy: Darla is notable for being the first character to be seen onscreen in Buffy the Vampire Slayer. In the opening scene of the very first episode, Darla is shown breaking into a school with an unnamed guy. The scene sets the guy up to be a threat, but in a clever twist, Darla is revealed to be a vampire. Her backstory is expanded on in the episode, "Angel", where she is shown to be Angel's sire and his former love interest. In the same episode, she is killed by Angel. She makes two further guest appearances in Buffy during flashback sequences.

One Of Buffy The Vampire Slayer's Underused Villains Sets Up A Perfect Spinoff
Buffy the Vampire Slayer's reboot could benefit from focusing not on the show's existing heroes, but on one of its most underrated villains instead.
In Angel: Following her relatively small role in Buffy, Darla played a more prominent part in Angel, where she appeared at least once in every season. At the end of the first season, Darla is resurrected and used by Wolfram & Hart to try and get Angel to lose his soul. Darla and Angel eventually sleep together, and she becomes pregnant with his child, something that should be an impossibility. In season 3, Darla kills herself so that her child can live. In seasons 4 and 5, she appears in visions and flashbacks, respectively.
4 Drusilla
Played By Juliet Landau
In Buffy: Drusilla is the sire and love interest of Spike, who s him in Sunnydale in Buffy's second season. Along with Spike and Angelus, she serves as season 2's big bad. Originally a young Catholic woman, Drusilla was turned into a vampire by Angel, but not before he drove her completely mad. Drusilla has a childlike demeanor and often speaks in total nonsense. Following season 2, Drusilla makes five more appearances in Buffy, both in the present and in flashbacks.
In Angel: After Darla is resurrected, Drusilla is brought in by Wolfram & Hart to turn her back into a vampire. The Angel season 2 episodes, "Reunion" and "Redefinition", therefore, depict Drusilla and Darla causing chaos around Los Angeles. As well as this, Drusilla shows up in a handful of flashback episodes in both season 2 and season 5.
