I was raised primarily by my step dad, Steven V. Scott. In recognition of that, I chose at a very young age to adopt his surname Scott, rather than the surname "Crawford" of my biological father.
Steve didn't even have a high school diploma and was operationally inept as a father in many ways - having himself come from a dysfunctional family - but emotionally he was 100% committed.
I don't remember exactly when, but at some point when I was little Steve gave me the nickname "Superman." He used it unironically, and continued to use that nickname frequently ever since.
I believe it was Abraham Lincoln who said "Nearly all men can stand adversity, but if you want to test a man's character, give him power."
Superman has practically unlimited power, but commits to doing the right thing, no matter what. There is no cost/benefit analysis.
It's one of the best nicknames a father can give to his child.
