History
Skyler Yin was born and raised on the Island of Patch, the only child to Richard and Christina Yin. Whilst there, he became close friends with his neighbor's daughters, Ruby Rose and Yang Xiao Long. Soon afterward, they met Dante Williams, and the four of them were inseparable. When they were old enough, the four of them joined Signal Academy.

Skyler's parents, in an ironic twist, worked in a Faunus-heavy environment where, due to discrimination against Faunus out in the world, humans were discriminated in the workplace. So while Skyler didn't have anything against Faunus (one of his friends outside of Signal, Adam Taurus, was a Faunus), his parents did. While they weren't nearly as bad as others, Richard and Christina showed distaste through looks, not actions. Unfortunately, looks were enough.

After visiting his parents one weekend during his first year at Signal, Skyler witnessed the White Fang murder his mother and father right in front of him. It is unknown to everyone but Skyler why they left the kid alive. Skyler refuses to talk about that night. But it furthered his resolve to become a Huntsman.

He graduated Signal at near the top of his class, guaranteeing him a spot in Beacon. But a few months after the Battle of Beacon, Skyler hoped to join Team RNJR and go to Mistral with them.

His current whereabouts are unknown.

Relationships
Team RWBY
Ruby Rose: His friendship with Ruby is close to sibling-like. Ruby considers him the big brother she never had, and he considers her as a little sister. The two's friendship grew stronger once they became leaders of their respective teams, with Ruby coming to him for advice on leadership.

Weiss Schnee: Though originally thinking Weiss was a racist, spoiled rich kid, Skyler dug deeper and looked at her situation from her point of view. He was pleasantly surprised by what he found. He finds Weiss honorable, and, while cold at first, she eventually opens up. Weiss considers Skyler basically a much nicer version of her brother, Whitley. She admires him more than she'd like to admit.

Blake Belladonna: While Skyler had a crush on Blake throughout the first and some of the second semester of Beacon, Blake never saw him past the "friend" category. While the two have become closer, they've never ventured past the friendship line, especially since Skyler moved on to someone else.

Yang Xiao Long: Yang is that someone else. Ever since they were kids, Yang harbored a small crush on Skyler, with him remaining oblivious to it for the longest time. And while he did have feelings for her for a bit while in Signal, he buried them because of Yang's flirtatious nature towards every male in the school. Though the feelings came back to bite at the school dance in Beacon, where the two confessed and began dating. Yang loves the fact that their relationship is also a pun: Yin and Yang. They've been a happy relationship since.

Team SHDW
Hazel Tikal: While indifferent about her for a day or so, Skyler's partner Hazel quickly grew on him. For a bit, he suspected Hazel having a crush on him, but realized after the dance that her feelings went towards Dante. He enjoys teasing the two.

Dante Williams: The two of them are very close, which makes sense, since they were childhood friends. As close as brothers, the two have also had a friendly rivalry, placing bets on who would get what first. Skyler teases Dante about Hazel, not only because of his feelings for her, but because Skyler got a girlfriend before him.

Walker Elliot: While Walker was a bit closer to his partner Dante more than Skyler, Walker and Skyler's friendship is still pretty close. While you won't find the two working together too often, their team attacks can be quite deadly.

Team JNPR
Jaune Arc: While still viewing Jaune as a stubborn idiot, at least he knows there's more than that now. While he likes Jaune well enough, Skyler gets frustrated that Jaune hasn't made Arkos a real thing yet.

Nora Valkyrie: If he was being honest, Nora scared him. He honestly doesn't know how Dante managed to make friends with her.

Pyrrha Nikos: While humbled by this world famous fighter, Skyler quickly discovered that Pyrrha was the one being humble. After getting to know her, the two became close friends. He even gave her a nickname: P-Money (mainly because he didn't want to go through the trouble of spelling her name correctly), and even considered asking her to the dance before his Arkos shipping side decided against it.

Lie Ren: Skyler hasn't really paid all that much attention to Ren, but has had respect for him. After all, anybody who can put up with Nora for years on end deserves praise.

Team CRDL
Skyler doesn't like them. Moving on!

Team CFVY
Coco Adel: While Skyler doesn't know a lot about Coco personally, other than her relationship with Walker, he respects her fighting abilities. I mean, come on, she has a briefcase that turns into a mini gun! Since that moment, Skyler's always thought of Coco as awesome. But after Skyler discovered Coco and Walker's relationship, Coco teased him, calling him a "c*ck blocker".

Fox Alistair: Much like Ren, Skyler hasn't paid much attention to Fox. He'll acknowledge him, but that's pretty much it.

Velvet Scarlatina: Velvet's another story altogether. After Skyler saved Velvet from Team CRDL's bullying, Velvet was infatuated for a short while. Skyler himself feels like she's under appreciated by the rest of the school, like at any moment, she could whip out some crazy fighting moves and beat up CRDL.

Yatsuhashi Daichi: Intimidated, thy name is Skyler. After losing a sparring match to this behemoth of a man, Skyler couldn't help but feel slight fear when Yatsu's around. Yatsu himself respects Skyler's strength and even admits that Skyler had the potential to go toe to toe with him in the near future. After Skyler's victory against Edward of Team EBNE, the second year commended him, admitting that Skyler had surpassed him.

Team EBNE
Nathan Bourbon: While this friendship is still in the works, the two at least have respect for each other. At first, Skyler thought Nathan was an always-serious jerk, who thought he could boss him around. But after the victory against Edward, Nathan was a good sport about it, giving Skyler another light to see him in. While they don't exactly trust each other, they probably will have to in the future.

Brittany Lilith: Whenever Brittany was around, Skyler couldn't help but feel very uncomfortable. She was a bit like flirtatious Signal Yang, but had dialed it up to eleven. He couldn't help but find her a bit creepy.

Edward: Edward flat out terrifies Skyler. This hulk trumped Yatsuhashi and Nora in that category the moment Edward got mad. While Skyler understood why, that didn't make Edward any less scary in his eyes.

Elizabeth Malacraft: Elizabeth reminded Skyler a lot of Ruby, if Ruby was a Faunus. He found her a pretty decent fighter, but still had a way to go when it came to close-ranged combat. Elizabeth herself, after talking with Skyler for a bit, compared him to Nathan, if the two had been set on different paths. She thinks Skyler and Nathan could be good friends if they just talked for a few minutes.
