What if you were Superman and saw Champion Walking towards you?
Ok your Superman and your 6foot3 and 225pounds and you happen to look down the street and you see these guy walking towards you and the closer he gets the bigger he gets what do you do. Remember Champion is 9foot2 and weights 5,050 pounds and looks like this.
After opening pleasentries, he asks if he would like to meet his friend Doomsday.

I would probably beat him up before he did anything, like everyone else, unsure that he was a criminal at all, and just claim it was because he looked funny if anyone asks.

Since I'm Superman I'd venture forth a guarded "hello?" If he continued to walk forward menacingly, I'd say, "identify yourself or I'll be forced to action." Then lazer him in the face lots and keep flying away. Just cuz I've got superstrength doesn't mean I need my pretty face messed up.
