Ultraman Wiki

"You will name the monster you transform into. ...Gorefang...... World Ender?.... Hurry up, I don't have all day long. Snake Darkness. It's great, Snake Darkness, even if its read backwards."

―Ultraman Tregear, Tregear's Story/Blue Shadow.

Snake Darkness (スネークダークネス Sunēku Dākunesu) is a Kaiju that appeared in Ultraman R/B The Movie: Select! The Crystal of Bond.

Subtitle: Evil Wish Beast (邪願獣 Ja Gan-jū)



Snake Darkness' name in Japanese is a palindrome. "スネークダークネス", written without the extensions (スネクダクネス), provides the same result written backwards.

Yukio Toi's illustration of Snake Darkness

Ultraman Tregear contacted Yukio Toi, a friend of Katsumi Minato, who gave up on his dream of becoming a game developer. Having eavesdropped their conversation earlier, Tregear found his prime candidate to cause terror and destruction. Tregear made his presence known to Yukio, who had concept art of Snake Darkness on another monitor, and him tempted by saying he will realize his dreams. Despite being confused and skeptical, Tregear nonetheless corrupted Yukio using his evil energy and transported him to Hoster 21 Star System. Soon after, Ultraman Rosso had appeared on the same planet to save a group of Pigmon from Mecha Gomora. After his battle, Yukio confronted Katsumi and transformed into Snake Darkness, saying that it is a kaiju's mission to defeat Ultraman. Snake Darkness easily defeated Ultraman Rosso and left through another one of Tregear's portals.

Snake Darkness making his appearance on Earth

Arriving in Ayaka City, Snake Darkness, and Yukio within, sought to destroy the world he hated so much. He was met with resistance when Ultraman Blu, Ultraman Geed and Grigio Regina, but defeated the three of them. Two hours later, Katsumi manages to get back to Earth and Ultraman Rosso reappeared, but they were beat down once more when Tregear showed up. Refusing to give up, the Minato Siblings and Riku transformed once more. They were once again on the verge of defeat until Grigio Regina evolved into Ultrawoman Grigio, and restored the energies of Rosso, Blu and Geed. Snake Darkness and Tregear still had the upper hand and even had Geed transform into Ultimate Final to match them. The Minato Siblings also joined their hands and unleashed the Makoto Crystal's power, fusing into Ultraman Gruebe.

Snake Darkness and Tregear vs Gruebe and Geed Ultimate Final

Snake Darkness and Tregear alternated between fighting Geed and Gruebe, who are now finally able to match them. Eventually, Snake Darkness is attacked by Gruebe using the Gruebe Kourin Shot, and was finished off by the Gruebing Beam. Despite Snake Darkness being destroyed in an explosion, Yukio was unharmed and floated back down in an orb of light, cleared of Tregear's evil influence as he goes back to his mother.
