Who is Waxnose from Trouble Is My Business and what is their importance?

Waxnose is a tall man who wears his hat low in the front. His face is wedge shaped and pointed at the end the same way an ace of spades looks at the bottom. His eyes are dark and his nose is unusually white. He carries a Colt Woodsman that has the sight filed off making the barrel look even longer, confident of his ability to shoot accurately. Waxnose allows Frisky to hang around with him, helping to keep him safe by controlling his actions. He never lets Frisky carry a loaded weapon, taking the firing pin out to ensure he doesn't act too impulsively.
