New one
Hint: Character (one of my favorites)
It takes one to know one, the old adage goes,
Well I am one, so i know one, and I'm one of the pros.
I'm a pilferer, a cut-purse, in layman's terms, a thief.
I'm one of the best so my work is thorough, yet brief.
I steal from those who steal from others, a modern day Robin Hood.
But i keep all for myself, so I'm not misunderstood.
My clan's line is long, yet I'm the only one left.
But i'm not alone, in my little world of theft.
My gangs tight knit, and started with three.
But in my most recent outing, more friends joined me.
My rival was beat, then beaten once more.
My previous challenge was to open a great door.
With my hat and my Cane, I'm ready to go.
Those are my hints, who am I? do you know?
