(Loved Trope) Wait, this isn't an epic final battle, this is a tragedy
Avatar, Zuko vs Azula: Despite the visual marvel that is the fight and the construction of the battle between the two, one would expect an epic climax in the battle. However, the music doesn't follow it; it's slow and melancholic, which could be interpreted as a tragedy: two siblings fighting, causing death because of their father, one remaining firm and serene thanks to the love he received and the other crumbling in anger and blind pride, a situation that should never have been.
Arcane, Ekko vs Jinx: The fight begins with tremendous visual art, with the music accompanying the action in a frenetic way. They fight using a game they played as children as a basis, but when the music ends everything goes silent; what was a game with paintballs becomes gunfire, and those who were childhood friends playing together become adults trying to kill each other. When Ekko catches up to her, the blows are heard in a raw and brutal way. It completely changes from the battle of the Firefly leader vs Jinx, to Ekko vs Powder in a raw way
