Stop and consider for a moment that the design goal of her as a character was not to be overly trope-ish but to be precisely annoying in exactly the way that has annoyed you…
They have a consistent theme of turning tropes on their head by clashing the stereotype with anti-thematic elements.
Here we see the trope of the beleaguered youth who would be granted godlike power become a “hero” turned on its head by a total lack of endearing qualities. In fact her character is intentionally repulsive… And a better example for today’s youth because of this. Instead of being overly idealized to inspire a form of being and behavior they do the opposite and let us pick apart the flaws.
No matter who plays the game the overwhelming majority will witness her reactions and behavior as incorrect… And be repulsed by them… As a storyteller this is best for everyone who hears the story.
Everyone can use a reminder of how being a self centered arrogant twerp is terrible.
Edit: also I should mention I would like to throw her into Lava
