he did fight bellatrix and broke out of azkaban alone.

I'd say that all of them fit his character.

and arrogant!!

Loyal, Talented, Brave, Reckless!

i think Loyal describes him best
and so does Brave ^^

Brave and Arrogant too!

brave and risk taking but very good in heart

I can't just pick one! =P

& loyal

All these words describe Sirius. One that's not here that should be is "Loving", but I guess you could argue it is almost the same as caring... He's loving because of how much he loves and cares for Harry :)

&& Reckless, or course. I'd be in denial to say otherwise, but it's arguable that his recklessness is really bravery? Haha, well he was a Gryffindor.

Well I love him in every aspect, every view, every feature, evry language.....this is getting weird

like LoveFredW ...

he is loyal, brave, arrogant, reckless, caring, charismatic, talented etc..

The whole lot.

He has all of these characteristics. Some more than others though

Reckless, Loyal, Talented, Impulsive. (;

Loyal, impulsive and reckless are the ones which stand out the most.
