"The Avengers established a pattern, that not only would Widow change her costume and weapons, but also her hairstyle. She was trained to be a chameleon-like spy, so why wouldn't she be constantly switching up her appearance?"
Black Widow is, like the canary, a great idea as a character in general. She joined the avengers without powers and still has the ability to go up against the likes of Hulk and aliens. I used her electric baton idea for my character because he is pretty much all the superheroes on this board knocked into one.
