- Buffy: The Light and Dark Slayers, mirror images. Way more similar than they realize, or, are willing to admit. Here is a good gif set showing it.
- Angel: Broody Brunettes with a dark past, complicated history with a blond of the same gender, and both desperately seek redemption.
- Spike: Reckless, passionate, always second best, complicated love-hate relationship with Buffy, see Angel as a mentor figure for a time before eventually considering him a peer, and perhaps, friend. A few Spangel-Fuffy parallels in this gif set.
- Willow: Both start out friends with Buffy until a tragedy strikes, they then go to the dark side, finally understand how far they’ve fallen, and rejoin team good. Arrogant and sometimes callous, but still insecure. Want friendship/family, looks to older male figure as a role-model/father-figure, feed off of their incredible power, before foregoing it temporarily as part of their redemption.
- Tara: I didn’t realize this one until the other day when I saw this gif set. It points out similarities I hadn’t seen before. They’re both insecure, lgbt (well for Faith, I’ll never say otherwise regardless of whether the show spelled it out), have powers, are the outsiders, with a troubled childhood, something of an on-off relationship with a Scooby, that started when they realized that they had supernatural abilities in common.
- Giles: Former rebels (though still pretty rebellious, just not as much), dark past, now mentors to young Slayers, even when part of the gang they are always somewhat separate.
- Darla: Beg Angel to kill them (as seen in this gif set), Angel helps them with their redemption. Again, both are mentor figures. Evil at one point. Though they only know Connor for a short time, both have an influence on him, (Darla obviously much more, she’s his mom), and he only really seems to listen to them. Comparisons regularly made between them and Buffy.
- Drusilla: Troubled Brunettes with a history with Angel, and mental illness. Both have strong psychic powers (though, Drusilla’s are stronger), a desire for family. See Angel as a mentor. Have their experiences with their mental illnesses mocked by the good guys. Suicidal tendencies.
- Xander: Insecure, trouble with relationships, implied abusive family, feel like they’re the useless one’s in the group, working class, not a lot of interest in school stuff, nerds.
