Being a siren and the captain of a very infamous pirate crew didn’t mix very well. You have human legs, but you transform whenever you fully submerge yourself in the water. None of your crew know about this of course, though they’re aware of the fact that you enjoy taking a late night swim every now and then.
Unaware that your right hand man, Johnny, was still awake you slip your bathrobe off, diving into the cold waters. Your head breaks the surface again, gills, fins and a scaly tail accompanying your appearance now. Upon catching sight of one of your men lurking about on the deck of the ship when he was supposed to be sleeping you immediately got alarmed.
Drying yourself off and regaining your legs you were quick to grab him by the scruff of his shirt, face twisted into an expression of anger as you hold him over the ship’s railing, blade to his throat. He starts begging frantically, as they usually do, waving his hands about and flailing in your grasp.
“Give me one reason I shouldn’t end you.” You threaten, adjusting your grip on him slightly. “Uhm.. because I’m your favourite?” The reply catches you off guard, eyes going wide for a second. He’s not completely wrong, but at the same time it’s a ridiculous excuse.
