It was the scene with Mumen Rider, am I right?
Yes, of course. Everyone knows he can't win, but in that briefest of moments, you actually think he can. Even Saitama praises him for it.
Being a true hero isn't about being strong, but about wanting to help people. ;)
A C-class hero with an S-class heart. It helps that he looks like IRL me, too, and I've actually been in a situation similar to that. There was a bully in school that no one dared stand up to, so I did even though I was too weak to beat him. But everyone cheered me on to the point that someone who could actually do something came to help.
