For @Blossomstream. Next oc will be Raven That Soars To The Moon.

Blackstorm

This name is kinda cool. Black- isn't used very often, I think some people just find it boring. -storm is more common, but it suits his personality. I like this name, it isn't overused but it isn't that original.

Tom

Don't really have anything to say so...

Blackstorm is a white tom with black spots and a black nose with amber eyes

It's a bit odd that BLACKstorm is white but I'm sure his name comes from his spots. I like that. Thanks for specifying the nose color, that's cute. Amber eyes are underused.

Senior Warrior

For some reason I imagine him as younger but ok

RiverClan

Oh, didn't expect that. The name makes it seem like he'd be in Shadow- or ThunderClan.

Rude, snappy, wise, observer

Hmm. Most people don't call their oc an "observer." That's really cool, I like that you added that. But I'd like to know more about him. Four personality traits isn't really enough to judge his character.

Blackkit was an only kit. His mother, Graystorm died of black cough. His father, Tealstar, was devastated. At 6 moons he was apprenticed to Yellowtail. When he was 12 moons he became Blackstorm. At 23 moons he became mates with Fernpelt, a nice yet  distant she. When he was 34 moons Fernpt gave birth to Flamekit(Flamewhisper) and Bluekit(Bluefall)

Cool, I like that you mentioned how old he was when certain things happened. However, this is quite.. vague. I'm left with a lot of questions. When Graystorm died, was he still a kit? Did he have a foster mother? Whatever happened to Tealstar? You mention that he was devastated, which makes me think that something would happen to him in the future, but he isn't mentioned after that. Didn't anything interesting happen other than him finding a mate and kits?

Mate: Fernpelt
Son: Bluefall
Daughter: Flamewhisper

All cute names.

5/10. His name is alright, but I really wanna know more about him. He needs more info on his personality and backstory.  Other than those things, this cat is pretty cool!
