    Summary

    Born from the foam of the tempestuous sea, lightning forming their souls, their kind would illuminate the vast depths of the oceans and bring life and light to every corner of the aquatic. So the tale goes.

    There would be nothing too unusual about the stranger wandering the beach if it weren’t for his apparent lack of clothes. When his curiosity about the naked man gets him into trouble, Dean finds there is much more mystery to him than his inclination towards nudism. In fact, Castiel, as he calls himself, turns out to be a genuine merman who, come night, grows a fish tail. With his general fascination for mystical creatures and fairy tales and Castiel’s lovable character, Dean falls hard for him.
    His days spent with the merman could be blissful if it weren’t for evil men with a taste for hunting supernatural beings and the countdown of days until Castiel’s transformation into human form ceases and their inevitable farewell.

    Summary

    The summer after Dean Winchester's high school graduation doesn't seem like it's going to be a very exciting one. Dean's life consists of working for Bobby at the salvage yard, taking care of Sammy, and helping his dad run the motel.

    That is, until a violent storm washes up a dark-haired, blue-eyed merman into The Beach Bunker's pool. With Castiel on land and sporting a brand new - albeit transient - pair of legs, the two of them discover that there's a lot for them to learn from one another. Not only about themselves and their present, but also about the past.

    Or,

    The one where Dean Winchester can't believe he's falling for the hot merman who got washed up in his pool. Since when was his life so friggin' weird?

    Summary

    Castiel, the youngest Prince of the Seven Seas, has the most absurd fascination with humanity. Against the wishes of his father King Charles he spies upon them whenever their strange vessels enter nearby waters. It's the most innocent of hobbies until his father discovers him. After a disastrous fight, the humans' vessel floats destroyed. Everyone aboard dead save for one human. Castiel, in a surprising show, saves him.

    He thought now he would have his own personal human to study, but he wasn't prepared for the human to stumble upon a forgotten merperson artifact and change both their worlds forever.

    Summary

    ["Shh," he whispered, ignoring his brother for now. The dude could have his freakout in a moment. Once there wasn't a hundred eighty pound hybrid thing threatening to squash them with a thrashing tail.] Either Dean had had too many beers, he was asleep, or he really had run into a mermaid—'scuse me, -merman-.

    Summary

    After Castiel rescued Dean from Perdition and the events of Season 4 occurred, he is back in Heaven preparing reluctantly for the Apocalypse. Dean still does not know who or what the being is that raised him out of Hell, and Castiel wants so badly to tell him and to help avert the end of the world. But when the angel tries to get back down to Earth, something happens to his Grace courtesy of a crappy deal and a magic spell….

    (And if that explanation is at all reminiscent of Disney's The Little Mermaid that is what I was going for.)

    Summary

    “So you finally gonna ask him out, brother?”

    Dean can feel his face flush but he acts cool. “Yeah. I think I am.”

    “Bout time.”

    “What’s about time?” Charlie says as she nuzzles herself in between them. His little fairy friend always butts her nose into his business. It’s a good thing he loves her like a sister.

    “He’s finally gonna ask the merman out,” Benny supplies when Dean doesn’t answer.

    “Oh. My. God!” she shouts loud enough for everyone downstairs to turn and look at her.

    Summary

    Summary for the fic by the lovely rustling_pages:
    It could be argued there are worse ways of meeting the love of your life than measuring their inseam for the fitting of a prosthetic merman tail, but if you asked Castiel about it, he’d probably disagree.
    Secretly being a merman in Hollywood was difficult enough, but working on the cheesiest tv show to ever exploit the worst tropes about merfolk - thank you, Gabriel - with annoyingly attractive soap opera star Dean Winchester was not how Castiel had invisioned his life going.
