This is a special kind of hero who just doesn't care about their great power, or the fact that they're a world famous adventurer, or the idol of millions, and so on. Despite the great power they possess, they always defer to their friends or allies, and rarely want to take the spotlight, even when their friends encourage them to do so. This isn't caused by low self-esteem or a guilt. The character honestly and truly doesn't think of himself as any better than anyone else, despite the great deeds they've done, or the inspiration they've become. In fact, such praise usually just embarrasses them.
