So people have brought it up and i have also thought about how Venomwoman's attack / power works. I have thought that it works in two ways, as a projectile and an injection. Like real venom its most effective when it's injected right into her enemy, i think it can eat through the weaker materials in robots, but its hardly a one hit kill with the injection. As a spray it can do minor damage but nothing long term, and could be used to dissolve things that are in the way
