A good protagonist is vital to placing an anime in the top-tiers. Heroes who undergo development, are relateable, have a strong reason to act, and ultimately make the sacrifice to save the day.
But what if the champion got swayed by the allure of the dark side. What if always doing the right thing wouldn't lead to the best outcome? What if the dark side offered something more that would take them closer to their goal?
There have been moments where the protagonist allowed themselves to be overcome by the dark side. They may not have become full-fledged villains, but were treading down a path to becoming one.
