Not every important anime battle is decided by the protagonists. Actually, there are plenty of amazing battles that focus on side characters instead. For this article, we're defining "side character" as anyone who isn't the protagonist. So, while All Might is a pivotal character in My Hero Academia, he isn't Deku, so he counts.
What are the best anime side character fights? Well, there's the aforementioned battle between All Might and All For One, which sees the end of All Might's career and passes the torch to his mentee. Looking for something a little more old school? There's the fight between Toguro and his former ally Genkai in Yu Yu Hakusho, which isn't just an awesome fight, it also reveals something important about the main villains' past.
