Barman doesn't have an powers, and is a vigilante therefore he's not a superhero. And iron man relies on armour and tech to defeat people so he can't be a SUPERhero
W-elll.... According to merriam-webster:
"Definition of superhero
: a fictional hero having extraordinary or superhuman powers
'
also : an exceptionally skillful or successful person"
'
I'm not sure what to make of this definition since by that standard Bill Gates is a superhero
An alternate definition of superhero is "an extremely skilled or successful person". So, by definition, superheros like Batman, Ironman, and Blue Beetle are superheroes.
