It just walks up to them having memorized “Never Gonna Give You Up” and starts singing instead of making the siren noise, turns it into a dance party instead of a massacre A.K.A. A vegan sirenhead
Fun fact: the creature at 11:21 is called “Long Horse” or “Dream Horse” and is actually a friendly being. Whenever he appears, it is to warn humanity of upcoming disasters. Also, Trevor has confirmed that Long Horse and Siren Head are aware of each other’s existence.
that is...very odd. if they're aware of each other's existence, do they like....hate each other?? or just kinda, know they're there and just like "hey, i dont like you, but i dont wanna be around you. okay? okay." ???
Siren head: a tall creature with flesh like skin, teeth inside it’s sirens, it likes to eat kids, it blends in with telephone polls, plays warnings like the one you heard or mimics voices of the current targets relatives.

this is absolutely the most terrifying creature I have ever seen. its literally everything I hate: loud noises, implications of terrible things from the alarms, long limbs that arent proportional. god this thing is terrifying and fascinating
*Story of siren head:* Siren Head is a 40-foot-tall humanoid creature with a heavily emaciated, near-skeletal frame covered in dried, mummified flesh the color of rusty metal. His limbs are disproportionately long and thin, with arms as long as his legs, ending in huge, bony hands. Where his head and neck would be is a thin pole of flesh with two sirens attached to them (hence the name), and several black wires snaking around his "neck" and into his upper shoulders, pressed against his abdomen. These speakers are the only metal parts of his body, fused to the neck by tendrils of skin and capable of swiveling around it much like the head of an owl. Some images depict Siren Head's speakers with toothy, lipless human-like jaws and a long, retractable thin snake-like tongue, though Henderson has said that the teeth are only visible on a certain radio frequency. True to his name, Siren Head's speakers can play various types of loud noises, typically air raid sirens, garbled music, conversations, or emergency broadcasts. As expected, Siren Head is very hostile and dangerous. Siren Head is mainly located in rural towns and wooden areas. The victims of Siren Head are lost travelers, hikers, and even little children. If the sounds of someone in distress are released, it can be a method of Siren Head trying to lure the victims into the woods. Since Siren Head can blend in very well with trees, people do not even notice Siren Head, so that he could make his brutal attack at any time, and capture his victims, while the sound of their loved ones talking are being played from Siren Head's sirens. His powers include: Superhuman strength Superhuman speed Sound manipulation Shapeshifting Stealth And stalking If you think about it, this thing is truly terrifying.
Long Horse is a specimen that has a horse’s skull as a head, and an infinitely continuing neck, it’s main body has never been found, long horse is actually something that is trying to help people, when long horse is seen, it is usually meant as a warning of danger, Long Jones’s is not dangerous at all, it just warns us that danger is approaching....
Fun fact: Trevor Henderson made Siren head back in 2018, he’s 40 ft tall and lures his victims by playing people in distress (known to be his victims last noises) in the woods where there are hikers. He’s probably Trevor’s best creation yet! Edit: I didn’t finish the video and I didn’t know he explained all this stuff, that’s my bad haha!
Unless they reproduce via budding Imagine a siren head ripping a siren off and throwing it as far as they can, not wanting to interact with its offspring.
I actually have a fear of giants, and huge things like that. Ranging from dinosaur to Titan size, I'm mortified. And sirens, distress signals, alerts, weather alerts, and any of those types of sounds horrify me. Sirenhead is my worst fear.
Skulls 'n' Bows mark later “he doesnt have a penis” ...i think i can imagine why either they’re lesbians or they have genitals in their mouths, like snails
They’re designed that way to activate your fight or flight so that you act during emergencies and not sit there and chill. That’s why people freak out and start to panic when they hear sirens and alert systems.
i live in smalltown midwest where the tornado siren goes off twice a day - one for noon and one for six pm so that siren in particular i am completely numb to. deadass the college i go to - in a city that doesn't do the noon thing - had a tornado warning going on and i literally just casually strolled across campus to go get food instead of taking shelter like literally everyone else was
Imagine the alert system noise was changed to the most chill person with an astrailoan accent saying, "Oi mate, there's a goddamn tornado coming. I'd appreciate it if ya head to shelter or something mate."
When they put on the emergency alert and/or weather alert sound, it scares the shit out of me for some reason. I understand fight or flight, but like... That sounds like horror movie shit
Everybody gangsta until you hear siren head plays really loudly la Marseillaise while running at you *L’ÉTENDARD SANGLANT EST LEVÉÉÉÉ* it said while grabbing your blood covered legs in the air, your hips detached of your body
IKR, hopefully thanks to people like Mark, more people find out about Trevor and find his art. As the creator more people need to know who he. I really wanna commission him for some horrifically cool shit.
@@theinkslicer YES i hope so!!! i know some really really cool urban legends or scps (like long horse) that he could do crazy art of!!! he's literally the only artist who can bring stuff like that to life ugh he's so cool
Everyone is gangsta till someone says an “everyone is gangsta till...” joke, and now you have to fulfill your offer to sacrifice yourself to siren head
I'd say Slender Man is still much more terrifying. Siren Head is incredibly scary, but it seems more like a huge, lumbering monster you'd see as a boss fight in horror-games, like The Evil Within for example. A handful of soldiers could probably fight it off. Slender Man, OTOH, is a vicious, otherworldly lorecraftian creature that psychologically tortures you to death, or simply turns you into a mind-slave, with just its mere presence alone, can teleport and attack you in any direction, and is basically immortal.
Andre B who said siren head isn’t immortal? Slendy was given years to develop, and Siren Head was made relatively recently, and hasn’t developed yet. it’s unfair to say SH is inferior, since it hasn’t had time to develop or have a description of powers. it’s not even made into an SCP or a real skillset.
At 6:15 My theory is that the player didn't actually escape and is the one screaming, the sound of the car is Siren mimicking the sound to trick the player.
Mark: "How did I not know about this game" *Flashbacks to his recent livestream* Past Mark: "I don't take game recommendations" Me: Because 'YoU dOn'T tAkE gAmE rEcOmMeNdAtIoNs'
mischieviouscreature I mean people in Marks live chats do take spamming to a whole new level. He has said a million times that he doesn’t take game recommendations (for obvious reasons), yet 99% of his chats and comments are inevitably game recommendations... It’s as if people can’t understand a very simple request or have anything of value to say.
Some of Tevor Henderson's creations are actually neutral to even benign, such as Long Horse (11:19). According to his posts, Long Horse is usually seen just before a catastrophe but it is assumed Long Horse is trying to warn about it and is not the actual cause of the disaster. The name Long Horse comes from the fact that you can never see the start of its neck, it always trails off just out of sight or into infinity.
Okay just for the basics: Siren Head is a 40-foot-tall humanoid creature with a heavily emaciated, near-skeletal frame covered in dried, mummified flesh the color of rusty metal. As expected, Siren Head is very hostile and dangerous. Siren Head is mainly located in rural towns and wooden areas. The victims of Siren Head are lost travelers, hikers, and even little children. If the sounds of someone in distress are released, it can be a method of Siren Head trying to lure the victims into the woods. Ancient cave paintings of Siren Head depicting him engaged in combat with ancient humans have been found all over the continent of North America, which indicates that Siren Head is not a new species on earth. Strength: It is believed that Siren Head is extremely powerful due to his size. Siren Head is able to break down trees or various heavy objects whenever he wants. Speed: In one sighting of Siren Head, a couple reported that Siren Head can be super-fast. The couple were driving home, until they saw the graveyard. They ended up checking out the grave, where they saw Siren Head. According to the woman, Siren Head started running towards them at an extreme speed rate.
Here's a fact Mark: Trevor said that Siren Head, and his presence, is a sign of bad stuff. I forgot what exactly, but baaaad stuff. That horse skull with the long neck and black hair patches is actually a warning. When you see it, it means a disaster is coming. Siren Head appears during things like Tornados, Earthquakes, a murder, etc. While the horse (Long Horse) appears before they happen to warn you! Theres also another with an upside down head that appears in photos OF THESE disasters. His creatures mostly revolves around bad incidents, fear, and pain. My theory is that they all come from the same place/dimension (story wise. They are not real)
Ch3rry_T0mato '5' well although we don’t know it’s exact length at night before the Holocaust in space it covered around half the earth least from Elon musks POV
Ch3rry_T0mato '5' it doesn’t have a true length it stretches off infinitely out of eyesight and it can grow new neck joints and retract the at will whenever you hear a popping crackling sound long horse is nearby.
What if they are real? Think about it... why would the public go over some random mentally ill people(s) creations? What if SCP is in area 51? I have lots more proof.
I’m so glad Trevor is more and more getting the recognition he deserves. His work is amazingly creepy and creatures like siren head and long horse have so much potential in horror fiction
As I recall Siren head is an entity the embodies the human emotions of panic and fear as well as all of the disasters they cause to befall each other. Thats why its head is a siren, it mimics the sounds of our warning systems make to illicit reactions of panic. Bomb Sirens, TV warning broadcasts, SOS signals. Any sound we have learned to associate needing to be fearful or on edge. But ya the guy who made this creature, Trevor Henderson, is basically doing his own SCPish thing and hes pretty good at it. All of his creatures make you feel uneasy even if they are confirmed not to be dangerous. Also Mark I think a good video to do would be exploring his other creatures as he has lore for all of them. It would be cool to get his name out there as he really does deserve it.

*Story of siren head:*
Siren Head is a 40-foot-tall humanoid creature with a heavily emaciated, near-skeletal frame covered in dried, mummified flesh the color of rusty metal. His limbs are disproportionately long and thin, with arms as long as his legs, ending in huge, bony hands. Where his head and neck would be is a thin pole of flesh with two sirens attached to them (hence the name), and several black wires snaking around his "neck" and into his upper shoulders, pressed against his abdomen. These speakers are the only metal parts of his body, fused to the neck by tendrils of skin and capable of swiveling around it much like the head of an owl. Some images depict Siren Head's speakers with toothy, lipless human-like jaws and a long, retractable thin snake-like tongue, though Henderson has said that the teeth are only visible on a certain radio frequency.
True to his name, Siren Head's speakers can play various types of loud noises, typically air raid sirens, garbled music, conversations, or emergency broadcasts.
As expected, Siren Head is very hostile and dangerous. Siren Head is mainly located in rural towns and wooden areas. The victims of Siren Head are lost travelers, hikers, and even little children. If the sounds of someone in distress are released, it can be a method of Siren Head trying to lure the victims into the woods. Since Siren Head can blend in very well with trees, people do not even notice Siren Head, so that he could make his brutal attack at any time, and capture his victims, while the sound of their loved ones talking are being played from Siren Head's sirens.
His powers include:
Superhuman strength
Superhuman speed
Sound manipulation
Shapeshifting
Stealth
And stalking

Me too. Anytime I get an amber alert or the Tornado Warnings on the television in my room/living room, I get this feeling my chest. It's very creepy.
the whether alerts i'm afraid of because if it happens without the calm voice after i know something's wrong.

Am i the only one who gets TERRIFIED from alert system noises and just sirens in general. When I hear them I get so scared for some reason..
They’re designed that way to activate your fight or flight so that you act during emergencies and not sit there and chill.
That’s why people freak out and start to panic when they hear sirens and alert systems.
i live in smalltown midwest where the tornado siren goes off twice a day - one for noon and one for six pm so that siren in particular i am completely numb to. deadass the college i go to - in a city that doesn't do the noon thing - had a tornado warning going on and i literally just casually strolled across campus to go get food instead of taking shelter like literally everyone else was
Imagine the alert system noise was changed to the most chill person with an astrailoan accent saying, "Oi mate, there's a goddamn tornado coming. I'd appreciate it if ya head to shelter or something mate."

When they put on the emergency alert and/or weather alert sound, it scares the shit out of me for some reason. I understand fight or flight, but like... That sounds like horror movie shit

Nola Harrivel SEVERELY UNDERRATED COMMENT
I'd say Slender Man is still much more terrifying. Siren Head is incredibly scary, but it seems more like a huge, lumbering monster you'd see as a boss fight in horror-games, like The Evil Within for example. A handful of soldiers could probably fight it off. Slender Man, OTOH, is a vicious, otherworldly lorecraftian creature that psychologically tortures you to death, or simply turns you into a mind-slave, with just its mere presence alone, can teleport and attack you in any direction, and is basically immortal.
Andre B who said siren head isn’t immortal? Slendy was given years to develop, and Siren Head was made relatively recently, and hasn’t developed yet. it’s unfair to say SH is inferior, since it hasn’t had time to develop or have a description of powers. it’s not even made into an SCP or a real skillset.
Siren head is a living creature but he looks like a siren to lure people towards him and kills them

At 6:15 My theory is that the player didn't actually escape and is the one screaming, the sound of the car is Siren mimicking the sound to trick the player.
The Legendary Hero siren head can copy any sounds an even loved ones to trick a person so your theory might be true
That's actually a really cool theory
Don't know about that, but the screaming sound is made by the Siren Head, you can check that if you wait near the car a little longer.
But that's just a theory
A Game theory
this could be true because at 7:24 he doesnt make it to the car and the noise still happens

Some of Tevor Henderson's creations are actually neutral to even benign, such as Long Horse (11:19). According to his posts, Long Horse is usually seen just before a catastrophe but it is assumed Long Horse is trying to warn about it and is not the actual cause of the disaster. The name Long Horse comes from the fact that you can never see the start of its neck, it always trails off just out of sight or into infinity.

Siren Head is best dj on creepy pasta parties. There is never a party without them.
Okay just for the basics:
Siren Head is a 40-foot-tall humanoid creature with a heavily emaciated, near-skeletal frame covered in dried, mummified flesh the color of rusty metal.
As expected, Siren Head is very hostile and dangerous. Siren Head is mainly located in rural towns and wooden areas. The victims of Siren Head are lost travelers, hikers, and even little children. If the sounds of someone in distress are released, it can be a method of Siren Head trying to lure the victims into the woods.
Ancient cave paintings of Siren Head depicting him engaged in combat with ancient humans have been found all over the continent of North America, which indicates that Siren Head is not a new species on earth.
Strength: It is believed that Siren Head is extremely powerful due to his size. Siren Head is able to break down trees or various heavy objects whenever he wants.
Speed: In one sighting of Siren Head, a couple reported that Siren Head can be super-fast. The couple were driving home, until they saw the graveyard. They ended up checking out the grave, where they saw Siren Head. According to the woman, Siren Head started running towards them at an extreme speed rate.
Siren Head: *Sees human*
Also Siren Head: *I AM SPEED*
nice info my man 👍

Slender? Is that you? Lol.
@Mindustry Lancer turret 096 does the Same When he's face is Sawed
Here's a fact Mark:
Trevor said that Siren Head, and his presence, is a sign of bad stuff. I forgot what exactly, but baaaad stuff. That horse skull with the long neck and black hair patches is actually a warning. When you see it, it means a disaster is coming. Siren Head appears during things like Tornados, Earthquakes, a murder, etc. While the horse (Long Horse) appears before they happen to warn you! Theres also another with an upside down head that appears in photos OF THESE disasters. His creatures mostly revolves around bad incidents, fear, and pain. My theory is that they all come from the same place/dimension (story wise. They are not real)
So how big was the long horse boi that appeared before the Holocaust?
Ch3rry_T0mato '5' Probably as big as that one image where it’s just neck. There’s a skull, but then the rest of the screen is just neck
Ch3rry_T0mato '5' well although we don’t know it’s exact length at night before the Holocaust in space it covered around half the earth least from Elon musks POV
Ch3rry_T0mato '5' it doesn’t have a true length it stretches off infinitely out of eyesight and it can grow new neck joints and retract the at will whenever you hear a popping crackling sound long horse is nearby.
What if they are real? Think about it... why would the public go over some random mentally ill people(s) creations? What if SCP is in area 51? I have lots more proof.

His stuff that he has posted is vary creepy
As I recall Siren head is an entity the embodies the human emotions of panic and fear as well as all of the disasters they cause to befall each other. Thats why its head is a siren, it mimics the sounds of our warning systems make to illicit reactions of panic. Bomb Sirens, TV warning broadcasts, SOS signals. Any sound we have learned to associate needing to be fearful or on edge.
But ya the guy who made this creature, Trevor Henderson, is basically doing his own SCPish thing and hes pretty good at it. All of his creatures make you feel uneasy even if they are confirmed not to be dangerous.
Also Mark I think a good video to do would be exploring his other creatures as he has lore for all of them. It would be cool to get his name out there as he really does deserve it.
