Name: Streamfall

People think that Stream- is pretty overused, but really, I've never seen it! Also, points for -fall.  I've actually seen it used only once or twice.  (In a fanfiction called Storkfall's Rise (it's deleted) and one of my ocs, Splashfall. Points for that!

Gender: female

:T   *blares music* OOOOH OOOH OOOH I REALLY DON'T CARE 

Age: 32 moons

Nice age.

Clan: SandClan

SandClan. Aaah, my old CLICHE friend we meet again. I've actaully seen this name floating around. Not as common as FireClan, heck no. But not the most origanal.

Rank: Newly appointed deputy (as of now)

Deputies are A-MAZE-IN. I love them. (:

Crush?: Tideclaw

I like the prefix Tide-. But maybe change the suffix to either -storm, -ripple, -reed, or maybe something that is mainly used for she-cats like Tidepool, Tidelight, or Tidestream? 

Kit(s)?: None.

Good. Not all female main characters need kits. 

Appearance: average-sized white she cat with grey and orange calico markings and pale blue eyes.

I love this! Except the blue eyes. Maybe change it to the less used blue or golden? Also, maybe add a  blue-gray paw or something. Other than that, it's really cool!

Personality: independent, feisty, sarcastic, snarky. That's her no-nonsense deputy side, but she's also soft, bubbly and will have a joke.

There isn't really any flaws. Feisty and nonsense can be flaws, but nothing really major. 

Back-story: she was born to Flinttail and Dewleaf. A day after she opened her eyes, her littermate Frostkit got greencough and soon died. Streamkit and her now only sister, Willowkit, would ask about their dead sister often, wanting to know what she was like. Their mother always said, "Frostkit was as gentle as falling snow, and she will always be remembered."Willowkit and Streamkit eventually became apprentices. They trained hard, and eventually earned the warrior names of Willowpool and Streamfall. After the current deputy of SandClan perished, Willowpool was appointed the new one. Streamfall was so happy for her sister, and they spent the night out on the beach looking at the stars. Unexpectedly, a band of rouges appeared out of the bushes, insulting the two siblings because they were in a clan. Willowpool lost her temper and shredded one of the rouge's ears as a warning. The rouges attacked, grinning. Streamfall saw a shadow in the moonlight, and thought it was one of the rouges. The sliced the figures throat and looked down on the body. It was then she realised that it was not the body of a rouge, but the body of her sister.The rouges were cackling. Streamfall fought like a lion, driving them all off.On return to camp, she told Sunstar (SC leader) that rouges killed her sister, and was appointed new deputy for driving them all off. Even now, Streamfall still has nightmares about the grinning faces of the rouges and the limp body of her sister, lying in a pool of blood.

THIS IS THE MOST FREAKING ORIGANAL BACKSTORY I HAVE EVER SEEN IN MY WHOLE WARRIORS LIFE!

A BAZILLION EXTRA POINTS FOR YOU! 

Fun fact: Streamfalls fur always smells of salt because SandClan lives by a beach

That's really cool!

I give this OC a 9.4/10 for the the small cliche things. Also, if your OC ever should have kits, Saltwing and Poolfrost would both be adorable names for them. Lovin' this amazing stuff all my commenters have come up with!
