So I have been a fan of the Buffy/Angel series' for a long time and I think that they have some of the best written characters in any fictional universe. I want to know who everyone else thinks has the best story arc. I can't decide if it's Wesley or Spike.
Wesley started out as a bumbling fool, and then he grew into a capable fighter alongside angel, and then he betrayed angel not out of malice but because he thought he was doing the right thing. He later finds angel in his underwater tomb that Connor left him in to rot, while he has a morally ambiguous relationship with Lyla, all the while he's pining over Fred. When he finally gets to be with Fred she is soon infected with allyria (don't have a clue how to spell that) and her body is taken over by the ancient god, but he puts his feelings aside and tries to help her find her place in the world after he helped angel get her powers down to a more manageable level which actually saves her. While all that is going on he slips farther into alcoholism, and in the last battle he was beaten and while he laid there dying allyria shows up and finished off his adversary and as he was dying she asked him if he wanted her to lie to him again and he said yes, so she reverted back to Fred and gives him his last moment with her. I'm a 43 year old man and I will cry like a baby everytime I see that scene.
My other choice would be spike, he started as a vampire that had one goal to kill the slayer. Throughout flashbacks we learned that he was a failed poet and his life was taken by Drusilla, and then over the next decades he killed 2 slayers. When he was captured by the initiative he had a chip implanted in his brain and he couldn't hurt humans anymore but his pentient for violence put him on the same side as Buffy and her friends, after he spends quite a bit of time fighting along side the slayer he gains her trust and she helped him get the chip out of his head and he falls in love with Buffy and while she doesn't return his love she does find herself sleeping with him and when she breaks it off he is overwhelmed and he crossed the line and sexually assaulted her, he's sickened by his behavior he leaves and fights to get his soul back which he succeeded in doing. He comes back to show buffy that he's a changed man only to find that she still doesn't want to be with him but he's grown and accepts her wishes and still fights along side her to the end, where he plays a pivotable role in the final battle. He is then resurrected by Lindsey in as part of his plan to get back at Angel but when he discovered that he was being used he joins Angel and his crew to help them in the fight against evil where he once again plays a pivotable role in the last battle and saves a baby who is held by a demon clan and is supposed to be a leader for them in the future.
My hot take is that spike is more of a hero than Angel sure angel fights for against evil and he's on the right side of the battle between good and evil but his soul was thrust upon him as a curse that he feels the all pain and guilt that he inflicted on his victims, but spike fought for his soul and overcame the odds to become a champion of good.
I think that all the characters in both shows have incredible story arcs some of the best in all of fiction and I'm excited to hear what everyone else thinks and who they think are the best characters.
