Marrina vs Tsunami
Marina
Marrina was amphibious. She could survive in the ocean depths or on land indefinitely, and breathe in both environments. In order to survive the crushing depths of the ocean, her physiology was specially enhanced. Her strength, endurance, vision, and stamina were all heightened beyond levels attainable by humans.
To travel, she could swim with considerable speed underwater, and also create massive waterspouts to propel herself into the air that stretch several kilometers inland and can also be made to strike a target with considerable force. On dry land, she could run barefoot to any destination at tremendous speeds. She could also brace her body to withstand the full impact of a semi truck, completely stopping the vehicle dead in its tracks, while completely remaining unharmed herself.
When Marrina became enraged and her Plodex DNA took over, she would take on a more beast-like appearance. Her hands would turn into talons that easily cut through most material, and her skin produced a contact poison that could blind an individual. During her pregnancy she grew to gigantic size.
