In what sense?

@Omega1065 I mean Pure Good heroes who are comic reliefs, but at the same time, are not silly PG.

"Silly PG"? Do you realize that comedy isn't detracting for heroes unlike villains?

A category of that type would be pointless.

@Omega1065 Do you think that if a PG hero is always taken seriously both in-universe and by the narrative, he will automatically fall into the seriously good category?

I don't think it's actually nessesary. A hero shouldn't be taken seriously to qualify as Pure Good. He just shouldn't darken the history. That's all. But how can he darken the history WITHOUT corrupting qualities? So I think it's pointless.
