|Species||Cactus ball creature|
|First Appearance||Godzilla Island|
Gororin appeared in episode 179, Porcupine's Dillema. As part of a plan by the Xilien, a large, spherical cactus was sent to Godzilla Island during the dead of night. By the next morning, the giant cactus had gained the attention of the island's kaiju, curious about the new arrival. The following night, Anguirus moved in to investigate the cactus, which revealed itself to be an evil monster named "Gororin".
Gororin attacked Anguirus, and the spiked quadruped began to fight back before being scolded by the G-Guard Commander for causing a ruckus. Soon, Gororin started a full-on attack on the island, firing its needles in every direction. Growing large spines on its body, Gororin detached itself from the ground began to roll around, slamming into everything in its path. The monsters of the island tried to fight back, but the cactus was too fast and strong, knocking them all to the ground. Even Godzilla's atomic breath failed to injure it.
Later, Gororin tried to attack Anguirus as he slept, but the plant monster merely bounced off Anguirus' shell. The G-Guard Commander arrived with MechaGodzilla to apologize to Anguirus for his earlier scolding, but is nearly run over by Gororin. At the last second, Anguirus came to the rescue, pinning Gororin between his shell and a cliffside. Gororin's thorns dug into Anguirus' shell, causing the monster agony. The other kaiju arrived to help, but Gororin fired its needles at them, keeping them at bay. Godzilla tried to force his way through, but was eventually overwhelmed and fell back.
Nao moved in, piloting Moguera. She used the mech to apply a special type of weedkiller to Gororin, causing all of the cactus' spines to fall off. With Gororin now harmless, the other monsters proceeded to kick it around like a soccer ball until Godzilla kicked it hard into the air, into Xilien's ship, destroying Gororin on impact.
- Gororin has very sharp needles that can detach and fire off of its body & storms down on to its opponents.
