You were a sea god/goddess, and you had made friends with a merman, he would cheer you up when stuff bad would happen

One day while swimming you couldn't find him, worried you swim around the sea before you spot a ship, you see him on there... Chains on his body and a spear in his tail.

RAGE pulls you over the edge as you see him bleed, all you want to do is kill everyone on that ship for what they did to him. knowing you could with a single hand you could send that shit under water
