Of course it can! just because something is a filler doesn't mean it isn't canon! Fillers are Canon!!! You can't just say it isn't. Therefore it can be relied upon for factual information.

Why don't they use the abilities that help make them the strongest that they can be. It doesn't make sense to me. Does anyone know?
