Both feature main characters who are parents that would do anything for their children and have super-powered alter ego's. Both have to with conspiracy's and the main characters working for major corporations.
Witchblade and Tiger and Bunny feature single parents living the life of "super heroes" in order to support their young daughters. Both series have very heavy American comic book vibes (Witchblade is directly based on an American comic and Tiger and Bunny features many nods to American comics including a HArley Quinn and Joker-esque duo) and are more about fun than anything else.
