“You listen to me. I've been alive a bit longer than you, and dead a lot longer than that. I've seen things you couldn't imagine, and done things I'd prefer you didn't. I don't exactly have a reputation for being a thinker. I follow my blood, which doesn't exactly rush in the direction of my brain. So I make a lot of mistakes. A lot of wrong bloody calls. A hundred plus years, and there's only one thing I've ever been sure of. You... Hey, look at me. I'm not asking you for anything. When I say I love you, it's not because I want you, or because I can't have you. It has nothing to do with me. I love what you are, what you do, how you try. I've seen your kindness and your strength. I've seen the best and the worst of you... and I understand with perfect clarity exactly what you are. You are a hell of a woman. You're the one, Buffy..”
―Spike to Buffy Summers, "Touched."
Spike is the tritagonist of The Buffyverse-serving as one of the two deuteragonists of Buffy the Vampire Slayer and Season 5 of the spin-off series, Angel.
Initially introduced as a villain intent on killing Buffy Summers, he eventually becomes one of her allies and second love interest. He is "love's bitch", to the sarcastic comic relief, to Buffy's romantic interest. Their relationship that grows from miserable lust/mutually abusive to a genuine love. He eventually became a self-sacrificing hero, dying as a Champion at the Hellmouth. However, he is resurrected in the fifth season of Angel.
In the expanded universe, Spike is reunited with Buffy and continues helping her fight the good fight vs. the forces of evil.
He is portrayed by James Marsden, who also portrays Victor Stein in Marvel's The Runaways and Brainiac in Smallville.
Indomitable will: In all the pain and suffering, Spike has endured, he has an indomitable will. He also fought off the effects of the chip on two occasions; once while manhandling Xander while confronting him about resurrecting Buffy and a 2nd time while helping her fight off a cult of humans trying to sacrifice a young girl.

Notes and trivia
Unlike Angel, Spike never really repented for his misdeeds and did not turn good of his own volition - though in time, Spike would come to be a more heroic individual. Though he regained his soul, Spike loved Buffy even without it.
Even after they broke up, Spike and Buffy actually maintained a friendship after their relationship ended in between Season 11 and Season 12, with possibility at having a serious one someday into the future.
Buffy had only referred to Spike by his real name William twice; once in Season 4 and when she was breaking up with him in Season 6.
