It’s a criticism imposed onto female characters that lack realistic flaws and are said to be a ‘self insertion’ of the writer(s) as how they want to be seen by the world. It’s seemingly a more common complaint than ever in this tedious ‘everything is woke boooo’ era.
People that make a complaint like that in respect of a franchise like this should note that this is the series where the lead male hero has bigger biceps than most people have torsos - he once punched a boulder to get it out of his way… in a volcano.
