Siren!Dark Headcanons

Requested by an anon! Again, assuming you’ve read this list, ‘cause I’m operating under the same rules such as dehydration, hiding his tail, etcetera, etcetera

- He’ll prey on anyone and everyone, but he prefers to take boats in deep water. That way it’s harder to notice

- He mostly hunts when it’s convenient for him, but he’ll kill whenever he very well feels like it

- Also can read minds

- His teeth are razor sharp

- Extremely territorial. If you’re in his water, you can’t hope to see the next morning.

- His tail is jet black, but it shimmers blue and red

- Same as Mark, can walk on land if he wants to, but he never really wants to.

- Voice doesn’t work as well out of water

- He looks the same, save for more chiseled features

- still does the neck thing

Headcanons: Dark with a Siren S/O

Request: “heyy, i know you said requests were closed but when you do feel like writing again would you mind writing a bullet list or preference about either dark or his S/O being a siren? i don’t know if you’ve done this before but i find the idea really interesting, love your writing by the way!!”


• He would be actually quite surprised by the sway your abilities have on him

• Its almost intimidating for him, to be with someone who holds a power over him

• He goes into a trance-like stance when you sing and is embarrassed about it

• He sometimes sings too and you enjoy it, very much and make comments that he might be one too. He just chuckles and kisses you

• He is kinda jealous of your ability though. Its so much easier than his wooing tactics.

• He will often ask you to sing. Because he honestly loves it that much

• Compliments, beautifully worded compliments that make you swoon a little

• He has a recording you don’t know about. It was hard to obtain as he was narrowly avoiding the trance like state I mentioned earlier.

• He listens to it when stressed because your voice is just an instant stress reliever

• He doesn’t like you singing around other people because they might fall in love with you too! Protective Dark is protective.

Headcanons: Natemare with a Siren S/O

Request: “Holy shit your siren and dark headcannon is just what my friend and I were talking about rping except it’s the other ones dating Mare! If you’re free from your requests, could you do when Natemare’s s/o is a siren?”


• Don’t fight me on this: Duets. 

• Very spontaneous ones at that.

• He loves your abilities and he loves how it affects him. He gets so cuddly when he’s no longer in the trance. Possibly a bit flirty too.

• He brags about your abilities SO much

• Each time you use your abilities on him be will get you back. Playfully

• Unfortunately for you - he can disappear and lead you on a goose chase while using his siren like abilities

• He will mostly lure you away for hugs. and funtime ;)

• You two are like a musical power couple and its intimidating and cool 

• He does get jealous if you use your abilities on others though

• There was a small argument about it, now its just a boundary you don’t overstep
