I don't know, but I did spend a lot of mental time trying to figure out what kinds of superpowers a half-man, half-seacow would have, so I could make the story of Subject O, an experiment in creating animal/human hybrids. He was going to be O--the Humanatee!
...please don't hurt me.
Lets see, his bio would go something like this:
Mr. Oliver Limpit, a mild-mannered accountant for a large health care conglomerant, with the help of really questionable/morally ambiguous science and the love of Trichechidae Trichechus, became
O--the Humanatee!
As the lone sentinel of the Florida shore, O dispenses marine justice with a swift swat of his well-trained flipper.
Ever vigilant as he munches the tender sea grasses, shoal grass, manatee grass, turtle grass, widgeon grass, sea clover, and marine algae of his aquatic protectorate.
Evil, dread the swift, silent, and signifigantly gassy justice of
The Big O.
