Suggested by iKnowledge Cleo Sertori is a skilled mermaid who has learned a few different abilities over the years. She can create storms and manipulate water. While the latter is always a cool ability to have we can safely disregard it here since Namora has no issues with the water. The storms can prove to be a little troublesome, but Namora’s physical strength and speed will allow her to get up close with Cleo and take her out before it can get too intense. Namora is just on a different level. Namora wins.
