A Merman’s Tale
A Teen Wolf / Mako Mermaids / Once Upon A Time Crossover:
(based on this post)
For centuries mermaids and merman have snuck on land to live among humans, but when Stiles unwittingly discovers the secret of one of them - a merman called Zac - things might become a bit complicated. Zac fears that Stiles would expose him to the world, but instead Stiles is intruiged by Zac and starts falling in love with him.
Zac is warned to start a relationship with a human by his best friend Jésus, another merman, but Jésus also promises to have Zac’s back. Stiles on the other hand gets into an arguement with his best friend Derek, who for years now has been hiding a crush on Stiles.
Ignoring Derek, Stiles keeps dating Zac and the two of them grow closer and closer until an evil threatens to destroy their love.
Regina, a powerful sea-witch, rises from the ocean and demands that Zac returns to the sea with him, so that she can harbor his powers to rule over the oceans. Regina threatens to destroy both worlds, if Zac dares oppose her.
In order to save the world, Zac is willing to follow Regina, but help comes in unexpected form. Jésus - who might just be what Derek needs - seeks out Stiles and Derek and gets them to stand up against Regina with him and Zac. Together the four of them now aim to destroy Regina, but the sea-witch is not an easy enemy to vanquish and every battle against her might just end in death and destruction.
