Because of her sonic voice, Black Canary is one who needs to be gagged as quickly as possible, even before she can be fully tied up in most cases. Because her work as a heroine puts her in situations of being kidnapped a lot, she knows how to deal with surprise attacks and can be fairly difficult to capture. She isn't very good at rope escape though so any effective tie will keep her from getting loose for a good while, at least until someone can come find her. To reiterate, heavy gags are a must and should always begin with a full mouth packing or a good ballgag as the first layer. If she gets that gag off, it's all over. And since her outfit really only offers a nice view of her bust, make sure to emphasize that whenever she's tied in any pose.
