What types of combat do fans of Heroes enjoy?

I can just picture it: you're walking home late at night, you turn into a dark alley, and a group of "gentlemen" in tracksuits pulls up and politely asks: "Dear sir/madam, would you be so kind as to generously donate to the local alley's unfortunate, starving, and undernourished children? We're talking about your iPhone/pocket change/sausage. If you refuse, or take too long to decide, we'll be forced to challenge you to a duel with swords or rapiers (you get to choose the weapon), so we can wash away the shame of your refusal." :)
