By popular request, my Hardcore Diablo II character is...

(drumroll)

A Paladin.

I play a paladin in most any RPG. Since I'm a fighter who crusades for truth and justice in real life...

...I figure I'll play a similar character in my RPGs.

I'm playing an "Avenger" paladin build. It's a little uncommon, but not unheard of. The Avenger specializes on high-damage, single-target, elemental attacks. This is useful on the higher diffulty monsters, who are immune to certain types of attacks (physical, fire, so on). Nothing is immune to my paladin, as his total damage is spread across multiple damage types.
