* FandomRivalry: Inevitable, really, but surprisingly less common than you might think. Back in the old days, it was ''DragonBall'' vs ''Manga/SailorMoon'', ''Manga/FullmetalAlchemist'' vs ''InuYasha'', and DragonBall vs SaintSeiya.
** Nowadays, the main focus is on the Big Three (most popular shonen series over the past decade) - ''OnePiece'' vs ''Manga/{{Naruto}}'' vs ''Manga/{{Bleach}}'', with ''Manga/FairyTail'' and ''Manga/BlueExorcist'' recently entering the fray.
