If you have seen a huge green face staring out from a Thai mask, mural or performance, there is a decent chance you have already met Thotsakan.
He is the king of Langka, enemy of Phra Ram and basically the main reason most of the Ramakien's enormous war happens in the first place. He has ten faces, twenty arms, supernatural power and one of the most ridiculous crowns in the whole story.
I had seen Ramakien figures in temples and on stages while travelling through Thailand long before I properly knew who all of them were. Thotsakan is one of those characters that becomes much easier to spot once somebody tells you the clues. Green face. Fangs. Giant. Massive crown. After that, you start seeing the same visual language again and again.
Thotsakan is the ten-faced king of the giants in Thailand's Ramakien. He is the Thai counterpart of Ravana from the Ramayana. He rules Langka, abducts Nang Sida and becomes Phra Ram's main enemy. In traditional Thai imagery he is usually shown with a deep-green face, fangs, ten faces and twenty arms.
Thotsakan, Tosakanth, Totsakan and a few other English spellings can all turn up. They are different romanisations of the Thai character name. In this article I am using Thotsakan.
So who is Thotsakan?
Thotsakan is the king of Langka and leader of the giant — or yak — side of the Ramakien.
He is ridiculously powerful. Ten faces. Twenty arms. Loads of magical ability. An army behind him. A kingdom of his own. He is not some small monster who turns up for one fight and disappears again.
He is the main opposing force to Phra Ram.
And the huge problem at the centre of the story comes from him: Thotsakan abducts Nang Sida, Phra Ram's wife, and takes her to Langka.
From there, Phra Ram's attempt to get her back pulls in monkey armies, giant warriors, Hanuman, battles, magic, flying characters, underwater mermaids and quite a lot more chaos than you would probably expect from the basic sentence "a king kidnaps another man's wife".
If all of those names are new, start with our simple guide to what the Ramakien actually is .
Is Thotsakan basically Thailand's Ravana?
Yes. But "basically" is doing a bit of work there.
Thotsakan fills the Ravana role in Thailand's Ramakien. Ravana is the ruler of Lanka in the wider Ramayana tradition; Thotsakan is the ruler of Langka in the Thai story. Both abduct the heroine and become Rama's great enemy.
But the Ramakien is not just the Indian Ramayana with Thai names swapped in. Thailand spent a very long time making the story its own, and Thotsakan has developed inside that Thai literary, artistic and performance tradition.
That is why I think calling him "Thai Ravana" is useful when you first need to explain who he is, but it is not where the explanation should stop.

How do you recognise Thotsakan?
This is the useful part if you are actually travelling around Thailand and looking at murals, masks or performance.
Do not start by trying to memorise every yak in the Ramakien. There are loads of them.
Start with Thotsakan.
Spot Thotsakan
Green face. Fangs. Huge crown.
Traditional Khon gives every major character a controlled visual identity. The Queen Sirikit Museum of Textiles lists Tosakanth's prescribed colour as deep green. Once you add the fangs and the enormous multi-faced crown, he becomes pretty hard to confuse with somebody ordinary.
The colour is a massive help, but green alone is not enough. Other Ramakien figures can also appear green. The crown is where Thotsakan really starts giving himself away.
So where are the ten faces?
This confused me a bit when I first started looking into him.
You hear "ten-faced demon king" and imagine ten full-sized heads sticking out in every direction like some enormous mythological hydra.
That is not usually what the Thai Khon mask looks like.
Look upwards
Khon stacks the faces into the crown
Traditional mask descriptions arrange Thotsakan's faces through several levels of the headdress. So you still get the idea of ten faces, but it becomes one ridiculously elaborate piece of Thai theatrical design.
SACIT's Khon-mask material gets pretty specific about this. Thotsakan's mask has multiple tiers containing different faces, plus the main grimacing green face below.
It is honestly a brilliant bit of visual problem solving. A performer cannot really dance around with ten full-size heads attached to them. So the costume tradition compresses the whole supernatural idea into something that is still wearable and immediately recognisable.
And the twenty arms?
They are part of the same larger-than-human identity.
Multiple faces and multiple arms are a very obvious way of saying: this person is operating on a completely different level from an ordinary human king.
I would be careful with some of the explanations you see online about the ten heads representing ten exact emotions, sins or bits of human psychology. Those lists get repeated a lot, but they are not something I would present as the standard meaning of Thotsakan in the Thai Ramakien without much stronger evidence.
What we can safely say is that the ten faces and twenty arms make his extraordinary power visible.
What does Thotsakan actually do in the Ramakien?
The big one: he abducts Nang Sida.
That decision is what eventually brings Phra Ram's war to Langka.
Thotsakan has power, a kingdom and a huge network of relatives and warriors around him. But he becomes obsessed with Nang Sida and takes her despite her being Phra Ram's wife.
The decision that wrecks everything
Thotsakan takes Nang Sida to Langka
From here the Ramakien becomes a rescue story, a war story and, eventually, a story about Thotsakan refusing to back down even when the cost keeps getting worse.
There is an extra twist in the Thai Ramakien too: Nang Sida is Thotsakan's own daughter, abandoned when she was a baby because of a prediction that she would bring disaster to him.
He does not know who she really is when he abducts her.
Which means the prophecy basically circles back on him anyway.
Is Thotsakan just the bad guy?
He is definitely the villain of Phra Ram's side of the story.
He abducts Nang Sida. He refuses to give her back. He keeps the war going. Loads of characters die because of decisions he keeps making.
So I do not think we need to twist ourselves into knots pretending he is secretly the hero.
But he is also more interesting than a flat evil monster.
Thailand Foundation describes him as a tragic villain shaped by things that are actually very human: anger, pain, ambition, desire and pride.
I think that is a much better way to read him.
"Big green evil demon" explains what side he is on. It does not really explain why he stays interesting for an entire epic.
He looks completely impossible, but his problem is very human
Ten faces. Twenty arms. Magic. Giant army. Hidden heart. Visually he is completely over the top.
But the thing that actually ruins him is much less exotic. He wants something that is not his, refuses to let go of it and keeps pushing long after the damage is obvious.
For me that contrast makes him way more interesting than if he were simply "the monster Phra Ram has to kill".
Then there is the whole hidden-heart thing
This is another part of the Thai Ramakien that makes Thotsakan feel properly mythological.
He removes his heart from his body and keeps it protected elsewhere.
So when Phra Ram attacks him, simply hitting Thotsakan's body is not enough.
Hard to kill
His real weak point is not inside him
The heart is kept in a magical container under the protection of his teacher. Hanuman eventually becomes involved in getting hold of it, and Thotsakan can finally be killed when the heart is destroyed as Phra Ram strikes him.
I love this because it fits his whole character visually as well. Nothing about Thotsakan is normal scale. Not his face. Not his crown. Not his number of arms. Apparently not even where he keeps his heart.
Hanuman plays a huge role in getting around problems like this. If you have not met him properly yet, read Who Is Hanuman in Thailand?
Thotsakan really makes sense when you see the Khon version
A lot of his design starts clicking into place when you stop thinking of it as a normal human face and start thinking about theatre.
Khon performers traditionally fall into character groups including heroes, women, monkeys and giants. The giant and monkey performers are the ones who still use the elaborate masks.
He needs to read from a distance
The green face, wide eyes, fangs, crown and embroidered costume give the audience a huge amount of information before the character has done very much at all. You can tell this is a major yak character and somebody with serious status.
The Queen Sirikit Museum of Textiles specifically lists Tosakanth as the deep-green king and supreme commander of Langka's army.
A surviving early-20th-century Thotsakan Khon mask held by the Museu do Oriente identifies him very simply as the ten-headed demon king of Lanka and enemy of Phra Ram.
That is the thing with Khon. The design is decorative, definitely. But it is also doing a job.
The colours, crowns, mouths and masks help you read who is who.

Something worth looking for in Thailand
When you see Ramakien imagery, try reading the characters before worrying about the exact episode. White monkey usually gets you thinking Hanuman. Deep-green giant with a ridiculous multi-faced crown gets you thinking Thotsakan. I find the whole thing much more enjoyable once those figures stop being anonymous decoration.
That has probably been the biggest change for me while learning more about this stuff.
You can walk past something because it looks impressive, take in all the gold, colours and detail, and move on.
Then later you know who one of the characters is and suddenly there is a story inside it.
Thotsakan is really good for that because he gives you so much to work with visually.

Khon characters were made to be recognised
This is exactly the sort of thing I like about Ramakien and Khon subjects. They already have real visual rules behind them. The colour, mask, crown and character are connected to an actual Thai performance tradition.
You can enjoy the shapes and colour first. Then there is a real story sitting behind it when you want to go further.

Who is Thotsakan in Thailand?
Thotsakan is the king of Langka and the main giant opponent of Phra Ram in Thailand's Ramakien. He is the Thai counterpart of Ravana from the wider Ramayana tradition.
Is Thotsakan the same as Ravana?
Thotsakan is Thailand's version of the Ravana character. He has the same central role as the powerful king of Lanka who abducts Sita, but the Thai Ramakien developed its own names, episodes, character details, visual traditions and performance culture.
Why is Thotsakan green?
Deep green is Thotsakan's prescribed facial colour in the traditional Khon character system. It forms part of the visual language used to distinguish major characters on stage.
Why does Thotsakan have ten faces?
Thotsakan is a supernatural giant king whose traditional form has ten faces and twenty arms. The multiplied body parts make his extraordinary power visible. In Khon, the extra faces are incorporated into the elaborate multi-tiered crown rather than appearing as ten separate full-sized heads.
Does Thotsakan really have twenty arms?
Yes. Traditional descriptions of Thotsakan give him ten faces and twenty arms. Different artworks and performances may not literally show every arm at once, but the twenty-armed form is part of the character's supernatural identity.
Is Thotsakan evil?
He is the main villain opposing Phra Ram and is responsible for Nang Sida's abduction and the war that follows. Thai discussion of the character can still treat him as more than a completely one-dimensional monster, with pride, desire, ambition, anger and pain all contributing to his downfall.
What is the story of Thotsakan's hidden heart?
In the Ramakien, Thotsakan has removed his heart and stored it safely outside his body. This makes him extremely difficult to kill. Hanuman eventually helps obtain the heart container so that it can be destroyed while Phra Ram strikes Thotsakan.
How can I recognise Thotsakan in a Khon mask?
Look for a deep-green giant face, large staring eyes, fangs and a very elaborate multi-tiered crown containing additional small faces. That crown is one of his strongest identifying features.
