Suggested by Sonic Flex Mentallo is definitely a unique character. His whole powerset involves flexing his muscles and doing the impossible. The guy has a good amount of super strength but seems to lose as often as he wins. Meanwhile Nanny isn’t exactly the strongest of villains as she focuses more on mental warfare, but she is equipped with the standard amount of blasters and such. I imagine that the main question here is whether or not they would hurt Flex. Personally I think that I would trust Nanny to win in such a battle. Her arsenal is just potent enough to tip the scales here. Nanny 2 wins.
