Dagon is an extra-dimensional demonic entity who tried to invade this dimension with the help of his Lucubra army during Earth's medieval era. He was banished back to his dimension when Sir George defeated him by cutting out his heart with Ascalon, a powerful weapon given to him by Azmuth nearly one thousand years ago.


Dragon Diagon

One of Dagon's forms: a Dragon

In the legend of Saint George and the Dragon, Dagon was shown as a large black dragon. Its underbelly, claws and wings were green, and it had narrow red eyes with spirals in them.

When it manifests in the "real world" at the end of the series, Dagon is revealed to be a massive beast resembling a giant green octopus. Its "face" is a large mass of tentacles, with either a much larger tentacle or a tail sticking out of its back. It has brown armor on most of its body, with two hooked projections framing its red eyes. In this "natural" form, Dagon is extremely large; dwarfing even Ultimate Way Big.


Dagon is a very arrogant being and excessively power hungry. 

Due to the fact that he himself is power, Dagon sees himself as a very godlike and invincible being who deserves to rule all with his mind control. 

Dagon talks down to all others as if they are merely nuisances or specks (even referring to some as such). 

Dagon does have a sense of honor to the strong and a sense of caution in dealing with them. He addresses Sir George as "George the Triumphant," due to his past victory against him. He also seems to respect Gwen Tennyson, or at least her power. He sent Vilgax to deal with Sir George and Ben due to the danger that George presented to him. 



Carving of Dagon

In The Flame Keepers' Circle, Dagon was first introduced as a legendary alien god who is believed to have visited Earth many years ago and brought advanced technology to humans in the past. He is also believed to have sworn to come back to Earth to bring the "Golden Age". He claimed he would bring alien technology so that Earth will not have war, nor disease, just peace. His appearance was revealed in a carving.

In A Knight to Remember, Dagon took control of Gwen and explains to them that if Vilgax gets his heart, he will be able to take control of the entire universe. After Vilgax defeats the Forever Knights and the Esoterica, Dagon takes control of Winston and tells him that in order to be powerful enough to rule the universe, he must break the seal. However, this was a trick.

In Solitary Alignment, his shadow was seen in a flashback. Azmuth also notes that Dagon has enslaved 100 dimensions at the time.


Dagon's Dimension entry

Dagon's voice was heard in Enemy of My Frenemy, being called by the name Old One, a being who can bring dead people back to life. Charmcaster gave him six hundred thousand souls (from every living thing in Ledgerdomain except herself) and in return, asked to bring her father back to life. Spellbinder disapproves of this, saying that his daughter became a worse tyrant than Addwaitya ever was by doing so. Spellbinder says that even though he loves her, he can't stay in Ledgerdomain with her, knowing that his life was bought by the cost of so many others, and decides to leave again. He returns to the dead and the Dagon makes all the souls return to their bodies, saying that "such is the way of magic".

In The Beginning of the End, Dagon's voice was heard again when Sir George demanded to face him, but Dagon instead summoned his herald, Vilgax.

After killing George

In The Ultimate Enemy: Part 1, Dagon was able to turn every human into an Esoterica except for Ben's Team, Julie, and Sir George. Later, he took control of Gwen again and he tried to use her to break the seal. Eventually, he broke the seal himself, thus allowing him to enter Earth's dimension.

In The Ultimate Enemy: Part 2, after Dagon freed himself, Sir George immediately attacks him. Dagon then ordered his herald Vilgax to destroy Sir George, but he is nowhere to be found, and thus Dagon sends his Esoterica to defeat George. While Gwen, Kevin, and George fight a couple of Esoterica, Ben transforms into Way Big, and Way Big transforms into Ultimate Way Big. Dagon fights Ultimate Way Big and easily defeats him with acid rain, with none of Ultimate Way Big's attacks having an effect on him. He then proceeds to fight Sir George and Chromastone. After he defeats Chromastone and kills Sir George, Vilgax and Psyphon return with their machine. Thinking it was a weapon, Dagon used his laser beams on it; however the machine absorbs powers from other living beings and due to Dagon's essence being only power, he was fully absorbed within the machine. Psyphon fired the machine at Vilgax and he received all of Dagon's power.

At the end of the battle, Ben used Ascalon to defeat Vilgax by absorbing Dagon into it.

Dagon is a nigh-omnipotent extradimensional "demon". His heart alone is said to have the power to reshape the universe itself, and he claims that "his substance is power". His abilities include, but are not limited to:

  • Enhanced Strength:
    • Dagon is extremely strong, as he was able to lift Ultimate Way Big with his tentacles even after shifting into a relatively smaller form.
  • Enhanced Durability:
    • Dagon is extremely durable, taking multiple hits from Ascalon and Ultimate Way Big's attacks without any significant damage.
  • Flight:
    • Dagon is able to float freely.
  • Mind Control:
    • Like the Lucubra, Dagon can control minds, but to a much greater degree. He took over all of Earth in a matter of seconds, while still being partially trapped by the seal.
  • Resurrection:
    • Dagon has the ability to revive the dead.
  • Fire Breath:
    • Dagon is mentioned to have a powerful fire breath, although he is never shown using it.
  • Power Bestowal:
    • Dagon can give a portion of his power to other beings.
  • Laser Beams::
    • Dagon can fire powerful laser beams from his eyes.
  • Weather Control:
    • Dagon can summon acid rain and lightning.
  • Shapeshifting:
    • Dagon can freely reshape his own body into a variety of forms.
      • When battling Ultimate Way Big, he adopts a more serpentine form, with smaller tentacles on his head and a body formed from three large tentacles on his underside.
      • He is said to have adopted the form of a dragon during his first battle with Sir George.
      • Dagon can also change his size at will.
  • Regeneration:
    • Dagon can rapidly heal from seemingly any injury. Ascalon's energy waves left slashes on his face that quickly sealed, and tentacles severed by Ultimate Way Big's cosmic beams regrew themselves in seconds.
  • Transforming:
    • Dagon can transform other beings into Esoterica.
  • Teleportation:
    • Dagon can teleport anywhere he wants.
  • Immortality:
    • Dagon does not age, nor can he be killed by conventional means.
  • Magic Knowledge:
    • Dagon possesses great knowledge of magic.
  • Sharp vision:
    • Dagon can see very small things (compared to him).


Dagon's essence is power, which makes him vulnerable to having his power (and thus himself) absorbed by another. Technically, this makes him exceptionally vulnerable against Osmosians, though the idea never came up in the show.

Dagon's mind control can be blocked by protecting the head with certain metals, as well as mana. Ascalon can also protect its wielder from mind control.

Despite being resistant to damage from conventional weapons, Dagon is very vulnerable to Ascalon.

Dagon is bound to the rules of magic, as seen when he returned a payment from a refused bargain.

Dagon's heart

  • Vilgax was mistaken for, and pretended to be Dagon in The Flame Keepers' Circle.
  • Dagon mentions that his essence is power, which implies that he is technically an energy being.
  • Dagon himself appears to be based on the Dagon from H.P. Lovecraft's short stories which subsequently lead to the popular image of Dagon.
  • Dagon also shares many similarities with Cthulhu, another creation from H.P. Lovecraft:
    • Both are extra-dimensional creatures.
    • Both have mind controlling powers.
    • Both look like an octopus.
    • Both have attributes of a dragon.
    • In Enemy of My Frenemy, Charmcaster calls him "the Old One." Cthulhu's species were known as "The Great Old Ones."
  • Dagon having no heart is similar to Davy Jones (from Pirates of the Caribbean) having no heart either.
    • Also to note of Davy Jones, particularly his head, also resembles an octopus.
  • Dagon shares many similarities with the Evil Entity in Scooby Doo: Mystery Incorporated.
    • Both have been imprisoned for millennia.
    • Both have corrupted others to free them.
    • Both have absorbed or been absorbed by their servants however, when Dagon was absorbed, he was absorbed to the point that Vilgax took over his body. The Evil Entity however was only taken over for a moment before he re-gained his body but had a different form.
    • One major difference is that the Evil Entity was part of the Anunnaki who were sincerely helping the humans, whereas Dagon merely pretended to help them.
