Alpha (The Walking Dead)

"I've seen how you live. I've walked your streets. It's a joke. Life is blood and pain and sacrifice. You think you have accomplished so much, but I look around at what you've done... and I see children playing a game of make believe. You've built a shrine to a long dead world. We are animals who always pretended we are not. You work and toil towards restoring a life where you exercise so you can sit in a chair and let a box lie to you until all your thoughts are gone. My people? The Whisperers... our lives are true. We live the full lives we were always meant to. You strive to return to a life as slaves to our pretty desires... instead of recognizing the gift this world has to offer. The gift of freedom."

- Alpha's Ideology

Alpha is the third main antagonist in The Walking Dead comic series, the leader of the Whisperers, and the mother of Lydia. She makes her first appearance in Issue 132 holding Dante at gunpoint. She serves as the primary antagonist from Volume 22: A New Beginning to Volume 26: Call to Arms. Overall, she is the secondary antagonist of the series, behind Negan and in front of The Governor.

Appearances
Alpha personally captures Dante and Ken and take them to the Whisperers' camp. Despite the capture however, Dante says that Alpha and her group haven't harmed them in any way.

Alpha shows up later at the Hilltop Colony and demands her daughter back in exchange for Ken and Dante. Carl goes after them and gets captured. Rick, Andrea, Michonne and Dante search for Carl on horseback, but Rick gets captured by the Whisperers. Alpha is then seen holding Rick at gunpoint on top of a building showing him a massive herd.

While under her capture, Alpha talks with Rick: criticizing his way of life. She says that he is delusional, and that her way of life is the correct one in the new world. Carl confronts her: bringing up how she lets her daughter Lydia get raped. Alpha defends the rape of her daughter as a part of the natural order. After a fight with Lydia, Rick tells Alpha that he can keep her safe, and so Alpha banishes Lydia. Letting Rick go: she informs him that she marked the border between his group and the whisperers. The border she mentioned consists of nine heads of Rick's allies and friends, absolutely horrifying Rick.
