"Woman... I like you.."

―Gorothunder's first words

Gorothunder (ゴロサンダー Gorosandā)[1] is a Kaiju that first appears in episode 19 of Ultraman Taiga.

Subtitle: Thunderstroke Monster God (雷撃獣神 Raigeki Jū-shin)[1]


Ultraman Taiga

Gorothunder was considered a god of lightning, who controlled lightning throughout the universe. It is said that all who see him will meet their end. He was summoned to Earth by Ultraman Tregear to wreak havoc on humanity.

Gorothunder descended in a storm cloud near Kana Sasaki and Hiroyuki Kudo. He took interest in the former and captured her in his belly button piercing prison before growing to giant size. Hiroyuki was unsure of what to do since fighting him would endanger Kana, but Ultraman Taiga convinced him that they cannot save her if they do not take action. Hiroyuki transforms into Taiga to fight Gorothunder, but quickly changed to Ultraman Titas after getting knocked down. He used the Electro Buster, but it was overpowered by Gorothunder's beam, and he was then knocked down by Gorothunder using his club. Kana awakened and cheered Titas on, before he fired the Astro Beam at Gorothunder to knock him away. Titas changed back to Taiga and transformed into Tri-Strium.

Using the Taiga Tri Blade, Taiga narrowly slashes off Gorothunder's belly button prison, setting Kana free. He then uses the Titas Burning Hammer to finish off Gorothunder, who used his own beams in a futile effort to attack him. Withstand the Lightning Strike!

  • Gorothunder seems to be a homage to several monsters of Ultraman Taro, such as Mochiron, Live King and Dorobon.
  • Gorothunder's name might have come from the Japanese onomatopoeia, Gorogoro (ゴロゴロ), which is the sound of thunder rumbling.
  • Gorothunder's motif seems to be based on the Shinto lightning god Raijin, who creates the sound of thunder by beating his drums, which have Tomoe markings on them. He is also said to steal the uncovered belly buttons of young children who go out during a thunderstorm.

Ultraman Taiga The Movie: New Generation Climax

After Ultraman Taiga, Ultraman Rosso and Ultraman Blu were defeated by the Grimdo-possessed Ultraman Taro, the Gorothunder Ring was taken from Taiga by Kirisaki. Tregear later revived Gorothunder and other monsters to fight alongside him and Taro against the New Generation Heroes. Gorothunder fought against Ultraman Rosso and Ultraman Blu, and receives a power up from Grimdo. However, Rosso, Blu and Ultrawoman Grigio fuse into Ultraman Gruebe to finish off Gorothunder.
