One great 'humbled Harry Potter fanfic' could be one where Harry has to face his own insecurities and learn humility in a new way, like dealing with a new dark wizard threat while doubting his own abilities. Another might be a story where he is sent back in time and has to start from scratch, which makes him more humble as he realizes how much he took for granted. There are also fanfics where he loses his magic temporarily and has to rely on his friends more, which humbles him.
Definitely. The comic version of Homelander is portrayed as having greater strength and capabilities. This is evident in his confrontations and the scale of his power displays throughout the comic series.
