Ultraman Wiki

Detton (デットン) is a Kaiju that appeared in episode 3 of Return of Ultraman.

Subtitle: Subterranean Monster (地底怪獣 Chitei Kaijū)


Return of Ultraman

As Go was trying to help the injured MAT captain escape the foggy valley, the Kaiju Detton appeared. Go tried firing on the Kaiju to Detton's chargin. After a brief scuffle with the two MAT members, Detton noticed Sadola and the two Kaiju began to fight. As the battle raged on, Go decided to transform into Ultraman Jack and end the conflict himself. At first, Jack had a difficult time wrestling both Kaiju at first, but after separating the two Kaiju long enough from ganging up on him, Jack destroyed Detton with the Spacium Beam, and subsequently killed Sadola with the Ultra Slash.


  • The Telesdon costume was reused to create Detton.
    • Originally, Telesdon himself was scheduled to battle Sadola, but due to the deterioration of the Telesdon costume during the filming of Ultra Fight, the costume was loosely altered in the face to slightly resemble a different kaiju, enlarging the nose and straightening Telesdon's eyes.
  • Detton's roar is a modified Gubila roar.
  • Sadola and Detton's episode marks the first time in the Ultraman Series that more then one kaiju/seijin fought an Ultra at the same time.
  • Although not referring directly to the Kaiju himself, Aide Toriyama of Team GUYS accidentally mistakes Zetton's name as "Detton" in episode 27 of Ultraman Mebius.

  • Detton is one of the Kaiju that makes up Belyudra's right horn in Mega Monster Battle: Ultra Galaxy Legends The Movie.
  • Detton was a part of Alien Empera's army during the Ultimate Wars.
  • In the original proposal, Detton went by the name of Gormon.
  • During production, Detton's mouth-opening machinism was somehow broken, resulting in the mouth hanging open for most of his appearance.
  • In some monster encyclopedias, Detton is stated to have more "guts" compared to Telesdon, likely meaning its more reckless and bold.

Detton made a small appearance in this short novel as a Spark Doll UltraLived by Chigusa Kuno to fight Nosferu. After failing, she swapped it for Ultraman.


  • Before completely swapping to Ultraman, Chigusa expressed how unfortunate it was that she had Detton and not Zetton.

Powers and Weapons
  • Burrowing: While not being seen on how he appeared, and given that Telesdon is similar, it is possible that he burrowed himself out from the ground.

Spark Doll

"UltraLive, Detton!"

―Announcement via the Ginga Light Spark.

While the Spark Doll was never been in sale, but it does appear in Ginga's universe, where it becomes one of the options for one to use when the Ginga Light Spark appears.


  • Chigusa Kuno used the Detton Spark Doll to fight against Nosferu, (whom at that time was MonsLived by Android One Zero). Since Detton is an ordinary monster instead of a Space Beast like the latter, it was easily defeated and in the end, Chigusa swapped it with Ultraman.
