The only thing I can think of is Street Sharks, but I know that isn't it since the orca man was a bad guy in that one.

I think this should be a simple one. It was a cartoon, one of the ecologically-aware ones about some kind of ocean research facility. The main character was a remarkably ripped scientist who drowned in the first episode and was turned into an orca-human hybrid thing so he could breathe underwater by a rather annoying underwater merman child, who looked just like a sea monkey. I recall he would turn into the orca thing whenever he came into contact with water, whether he wanted to or not, and there were probably some evil polluting corporate types as well.
