I’ve made a character in HERO a decade ago, but not looked at it since. I may give it another look.
If you do, I recommend getting Ninja Hero. It's technically for 4th edition but it's still compatible with the latest (6th) edition. It has a plethora of martial arts, including European fencing. It also has a simple system for designing your own martial arts manoeuvres that you might like.
