Who in the world am I?

I can fluff
I can smash
I can write

Turn me around
and I will scar

More than one
then I'm red and far

Bonus (requires VERY specific knowledge):

I am the next best girl in pink.

You are a ...

... ram.

I can fluff

Rams have wool.

I can smash

Rams can butt. Battering rams can smash gates.

I can read, I can write

RAM is random-access memory that can be both read from and written to.

Turn me around and I will scar

Ram reversed is mar, which can mean to scar.

More than one then I'm red and far

Mars is the red planet. (Answer provided by OP. I first had thought about more than one ram, which didn't get me anywhere useful, of course.)

Bonus (requires VERY specific knowledge):

Or access to search egnines. :)

I am the next best girl in pink.

Ram is one of the protagonists of the Japanese light novel Re:Zero. She's a girl with pink hair.

• Perfect! I guess for people who watch Re: Zero, this would be too easy. For the "More than one then I'm red and far", more than one means pluralize it -> Mars. #RemBestGirl – bolt997 Jul 20 '17 at 7:07
• Oh, so the more than one is after turning around, which now is quite obvious. I don't watch Re:Zero, by the way, and didn't even know about it. – M Oehm Jul 20 '17 at 7:09

Is it

A cloud

I can fluff I can smash

Maybe a reference to Prince fluff in super Smash bros.

I can read I can write

I am lost on the other clues :(

• Nice one! But not exactly the word I'm looking for. The other clues are just as important. – bolt997 Jul 20 '17 at 6:41
