Gorosaurus (ゴロザウルス,   Gorozaurusu?) is a dinosaur kaiju created by Toho that first appeared in the 1967 Toho film, King Kong Escapes.


Gorosaurus' name might be derived from the Japanese word "gorogoro", meaning "thunder", and the Greek word saurus, meaning lizard or reptile. Another possible explanation may be that it's an intentionally corrupted form of Gorgosaurus , as both names are extremely similar in both English and Japanese; however, no offical word has confirmed the origin of the name.


Gorosaurus is a gray color all over, though in some highlights the color can change from a greenish tint or even a form of teal and blue, and has skin with pronounced scaly bumps. Gorosaurus has a row of triangular plates running down his back, as well as a bipedal stance, strong legs, fairly short arms, and a big head.


According to the Godzilla Movie Studio Tour, it said in Gorosaurus' bio that he is an abrupt descendant of Allosaurus. This is relevant to Gorosaurus' design, as most Allosauroid dinosaurs have a triangular-shaped head. It is also possible that Gorosaurus could be a part of the dinosaur group Carcharodontosauridae, which are closely related to the Allosaurus and succeeded their cousins in the later Cretaceous periods. This could mean that Gorosaurus survived the Cretaceous extinction event.

King Kong Escapes


Gorosaurus in King Kong Escapes

Gorosaurus lived on Mondo Island when he attacked Susan Watson and tried to eat her. King Kong attacked him and saved her. Gorosaurus used his Kangaroo Kick multiple times on Kong, but he was defeated when Kong broke his jaw.

Destroy All Monsters

Gorosaurus was living on Monsterland when it was taken over by the Kilaaks. He was sent to attack Paris, and he was called back to Mount Fuji. After he was released from his mind control, he helped battle King Ghidorah.

Gorosaurus also appears in the series Go! Godman, as a one-time enemy of the eponymous Godman. Godman ends up ripping off Gorosaurus's jaw.

The Gorosaurus suit here is in such poor shape that the inner support seems to be deteriorating. It makes Gorosaurus' torso look like its caving in.

Gorosaurus hitting King Ghidorah in Destroy All Monsters

Aside from the usual tooth and claw, Gorosaurus has been noted for using a "kangaroo kick" against foes like King Kong and King Ghidorah. This is Gorosaurus' most popular trait. Also, in the 1968 film Destroy All Monsters, Gorosaurus is shown with the ability to burrow underground. This is the only incident where this ability is shown.

Gorosaurus' battle against King Ghidorah showed his strategies. While fighting, Godzilla and Anguirus attacked the two outermost heads as a distraction, which Gorosaurus used to sneak behind King Ghidorah; his blind spot. Gorosaurus kicks King Ghidorah down to the ground, where the other kaiju pin him down and finally kill him. Gorosaurus is also known for being just as strong or even stronger than Godzilla when it comes to muscle strength.

RoE Gorosaurus

Gorosaurus in Rulers of Earth

Gorosaurus was seen in a flash back that the Mothra Fairies told Lucy in an attempt to explain the origins of all monsters. Gorosaurus was seen devouring two full grown dinosaurs, a Tyrannosaurus and a Spinosaurus, which were about to fight over a downed Triceratops.

Before he could eat his meal, Megaguirus attacked him, but the Allosaurus-like monster kicked the dragonfly beast and knocked her out of the sky. Gorosaurus was later seen frozen next to Anguirus. He is also present in the 'Land' monsters section of a cave mural.


In King Kong Escapes, much like Baragon, Gorosaurus' roar is also another modified Varan roar, but was more sped up and pitched. Gorosaurus' roar is also created from the chirp of Rodan, another one of Toho's gifted monsters.

In Gorosaurus' protagonistic role in Destroy All Monsters, Gorosaurus still was the same, but this time Toho had edited the roar and deepened, plus slowed the roar, to make the new Gorosaurus sound older. Gorosaurus is one of the very few monsters to be gifted with one of Godzilla's roars, during the fight with King Ghidorah. Gorosaurus also had several roars from other Toho monsters in Destroy All Monsters. Toho blended and higher pitched a particular chirp from Ebirah at the beginning of the roar. Coincidentally, Gorosaurus had one of Varan's unaltered roars at the time it destroyed the Arc de Triumph in France.

  • Gorosaurus was strangely shown to be burrowing in Paris in Destroy All Monsters. This role was originally intended for Baragon, however the Baragon suit was on loan to Tsuburaya Productions for use in the Ultraman series. Toho instead replaced him with Gorosaurus, having Gorosaurus "borrow" Baragon's burrowing ability. Gorosaurus was even referred to as "Baragon." By the end of the film's production, Baragon's suit was replaced and repaired, but he could only make a short cameo because the filming of scenes was almost over.
  • Gorosaurus is one of the three Godzilla monsters that have "saurus" in their names. The other two are Titanosaurus and Godzillasaurus.
  • Gorosaurus' role in King Kong Escapes is similar to the Tyrannosaurus that fought King Kong in the 1933 film.
  • According to Nobuyuki Yasumaru, the creator of Gorosaurus, Gorosaurus was one of Eiji Tsuburaya's favorite monsters.
    • Gorosaurus was the first monster Nobuyuki created. He later went on to creating suits for Ultraman and Ultra Q.
  • Originally in the production King Kong Escapes, suit maker Ryosaku Takayama was assigned in making Gorosaurus, but his concept of the monster was too pure and seemed at most wouldn't best fit Toho's special effects, as implied by Nobuyuki. Nobuyuki decided to create the Gorosaurus suit in his own concept.

    • I thought Goro meant fifth, because it was the fifth monster to appear in Toho showa timeline.
    • Gorosaurus' name could also be derived from Gorgosaurus, as well; they both have similar spellings in both English and Japanese. But I...

    • they seem to be pretty evenly matched. any powers in any games are available and gorosaurus obviously has his signature kangaroo kick
    • I think it could go either way. Goro is really strong so if he could get a couple of good hits he could win, but if Varan was fast enough to do...
