Kamacuras

The Kamacuras, known in the English dub as Gimantis, are a species of 2-meter tall praying mantises who were mutated by a failed weather experiment. Growing to 40-50 meters tall, these humongous insects are vicious opponents, though they are no match for Godzilla.

Showa History
A group of Kamacuras were mutated by a failed weather experiment. Finding a giant egg, they hacked it open, revealing a baby Minilla. They started to attack him, but his cries were answered by the arrival of Godzilla himself. The Kamacuras attacked, throwing rocks, one of which hit Minilla. However, Godzilla fought back and eventually killed two while the third Kmacuras fled the scene by flying away.

Later on, the Kamacuras returned, trying to eat Saeko the Island girl. However, Minilla came across the Kamacuras and attempted to save Saeko. He tried to blast the Kamacuras with his atomic rays, but they weren't strong enough and came out as weak smoke rings. The Kamacuras hit him in the face, causing him to whack a rock with his tail, which the Kamacuras hit back at him, which struck him in his face, stunning him. During the struggle, Minilla accidently knocked over some rocks which crashed into a canyon where the giant spider Kumonga slept, waking him from his sleep. At the same time, Godzilla arrived and blasted the insect twice before it fled. Kumonga then rose and captured Minilla. As he was about to kill the baby, the Kamacuras appeared and, seeing the giant spider, tried to fly away, but was webbed by the spider and brought down. Kumonga approached the Kamacuras and stabbed it with his poisonous stinger, injecting it with poison and killing it.

Millennium History
In the year 20XX, the Xillens deployed Kamacuras to attack Paris. The ship Eclair, attacked it. The Kamacuras was then taken back by the Xillens. It was then discovered that the Xillens were controlling the monsters. The Xillen ship's and Kamacuras destroyed the Eclair and Paris. The Earth Defense Force then released Godzilla from Antarctica. He killed 3 monsters and headed to Kanto Japan where Kamacuras was. The tidal wave from Godzilla destroyed the bridge that Kamacuras was on. He flew to the mountain nearby and used camouflage to hide from Godzilla. Then when the time was right Kamacuras flew towards Godzilla and head-butted Godzilla. Godzilla then threw Kamacuras into a electrical tower and it went straight through it's body, killing it.

Post Millennium History
Kamacuras was the first monster that attacked the world. It attacked New York in 1999, and was then killed with bunker buster bombs. In it's wake, it killed 2.5 million people.
