I remember a cartoon I enjoyed when I was a kid but for the life of me I can't remember what it was called. It was about aliens (I think they were aliens) living underwater and the main character was a human but when he goes underwater he transforms into an alien. I'm pretty sure it was a 90s cartoon as I recall watching it in the later half of the 90s and the art style seemed inspired by The Abyss. Anyone else remember this show?
