What types of combat do fans of Heroes enjoy?

It will be enough for me to know that in fair 1-on-1 battles, I will always or almost always win.

Well, I wouldn't say that it's "fair." If you are trained, experienced, and have the skills, then you still have an advantage over a simple ordinary person. But as it is, there's no point in fighting fairly in 2017. Why risk your health for... well, for what?
