Return of Ultraman

As Goh was trying to help the injured MAT captain escape the foggy valley, the kaiju Detton appeared. Goh 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, Goh 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 Specium Ray, 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.
    • According to "Ultra Kaiju Encyclopedia 6: Return of Ultraman", Detton is a sibling or relative of Telesdon. This would mean that they are of the same species which would make a lot of sense considering they look very similar.
  • Detton's roar is a modified Gubila roar.
  • Sadola and Detton's episode marks the first time in the Ultra 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 Beryudora's right horn in Mega Monster Battle: Ultra Galaxy Legends The Movie.
  • Detton was a part of Alien Empera's army during the Great Ultra War.

Mountain Peanuts

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.

Powers and Abilities

  • 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.
