Zero Two
Zero Two from Darling in the FranXX is the one character who completely took over the anime community in 2018. She is the main heroine and the most well-known parasite in the series. Her name is also Code 002. She's not the kind of person you usually fall in love with. Zero Two is a mix of a human and a klaxosaur, and she is known as the Partner Killer, which is a very bad thing. But even though there are scary rumors about her, her strong bond with Hiro is what makes the show so emotional. She is strong, deeply flawed, and impossible to forget.
Zero Two has a character design that is so good that it made her a legendary waifu. You can't miss those red horns and that beautiful pink hair that falls to her waist. She looks completely confident no matter what she's wearing, whether it's her classic red military uniform or her tight-fitting pistil pilot suit. She has a wild personality that includes playful teasing, wild aggression, and an overwhelming love for her darling. She always does things that are against the rules. She is impossible to resist because of her rebellious streak, sweet tooth, and famous catchphrase. Fans loved her because she pushes limits but really just wants to be loved.
It's not surprising that she rules over wallpaper galleries all over the internet. Zero Two fan art includes everything from dark mecha battle scenes to soft romantic cherry blossom scenes. Artists love to draw her sly smile or those bright teal eyes that seem to be staring right at you. A neon glitch or pastel Zero Two wallpaper is pretty much a must-have for your desktop if you want a background that screams "top tier anime girl energy."
