A landlubber!! So helpless that he could drown in his own bathtub.
Comic Books
I hate the sea. It's one of the few places where my radar sense is useless. Amplified sound with no direction. No sense of smell. No touch. Nature's sensory deprivation tank. And from the height I've just fallen from, I have no idea how deep I am. The only way to know which way is up is from the decreasing pressure on my eardrums. But I'm not thinking about that. All of my abilities have been replaced by wild thrashing while my brain screams "Don't drown."
