Okay. Me and my friend are rating this. I'm bold and she's italics. 

Hollowtwist

Yeah. I guess it's okay.

Hollow- is very underused. And -twist is okay. Seems strange to me.

Gender: Tom

Very original.

Most OCs are she-cats, so yay. *throws confetti*

Pelt: Dark ginger fluffy tom, red patches bended into fur. Amber eyes

Very pretty. I like the color.

Dark ginger is cool, and has become very underused and I love the red patches. Also, amber eyes is pretty beautiful.

Traits: Gentle, Strict, Honest, Akward, Nature Lover, Lazy

He seems nice. Not many OCs are lazy, like me! ;D

He has a nice amount of flaws and (unflaws? not flaws?)good traits.

Father: Bluestone(alive)

Blue- is overused. -stone is cute.

Agree with above.

Mother: Berrypatch(dead)

Berry is so cute! 

I love this name! And aw she's dead!

Brother: Frogpaw(exiled)

Sisters: Lilypetal(dead)

 Goldenwish(alive)

Mate: falive)

Kits: Blank Heart that is a Suprise(alive)Creek Water that flowd downstream(alive)Aspen that Falls(dead)

Your names are very creative.

I really like these names but I accidently deleated his mate's name. Oop

Backstory: As a kit Hollowkit was the runt of the litter. Except his family thought other. Suprisingly he lead his siblings into crazy adventures everywhere, sadly Frogpaw hated this and stopped doing what he said.When he became an apprentice he was lazier than a pig and hardly did much work.His mentor was Blackheart, an evil cat with a black heart.As a warrior he worked harder and the she-cat he grew close to as an apprentice(from the oppistite clan) and after two moons of being a warrior she grew pregnant. Blackheart told other lies and got the two banned from the clans.They joined a group on the plains called, Lion's In The Dark. Their kits grew up there and were called, Blank Heart that is a Suprise, or Blankheart, Creek Water that flows downstream, Creekwater, Aspen that Falls, which died at birth.(His brother was exiled for almost slaughtering Goldenpaw.

Origanal.  I like this.

You are very good at creating creative backstories and names! Only cliche I see is that he is the runt of the litter!

Overall, we talked and this cat deserves a solid 9.9/10. Only one point off for the runt part. Other than that, you have one of the best OCs ever!
