Suggested by Destroyer Lady Sif is a strong warrior so the question here is really whether or not her attacks will beat Hedorah before he gets a luck shot in. I’m inclined to say that she has this match in the bag. She may not have a lot of fancy super powers, but she is an Asgardian and so she possesses natural super strength. Her weapons are also crafted to be quite deadly and so the slices will hurt Hedorah. He will simply be hacked until he is no longer able to remain standing. Lady Sif wins.
