Original fiction staring Gfantis are regularly featured in G-Fan as well. Gfantis has taken on a variety of opponents around the globe and is currently the subject of intense observation and study.

Name
Gfantis was scientifically named “Gigantosaurus fantasticus” by professor Hank Taupier. Though the name can properly be abbreviated to G. fantasticus, reporter Sly Lyson further contracted it to Gfantis, and the name stuck.

Origin
Gfantis was “born” in the explosion of an experimental solar power plant on the south seas island of Kalihama, but his origin lies shrouded in confusion to this day. Though he resembles a dinosaur, he is unlike any presently-known species, and possesses some mammalian traits.

Abilities
Able to burrow underground. Solar radiation beam from crescent horn, oral heat ray, derives and replenishes power from solar energy, which can withstand high temperatures (can move through magma). An effective grappler, Gfantis can use his long tail as a whip. Is bipedal and quadrupedal as well.

Gfantis has taken on a variety of opponents around the globe and is currently the subject of intense observation and study.

Dogora (ドゴラ) is a gaseous jellyfish-like alien kaiju created by Toho that first appeared in the 1964 film, Dogora.

History
Dogora
Dogora first appeared in space, feeding on radiation. It destroyed a television satellite, causing it to mutate. It came to Earth and began eating diamonds and other jewels. A professor created a synthetic diamond, and Dogora was attracted to it. It melted the safe doors and ate the diamonds. It attacked a coal plant, and it was discovered that it feeds on carbon. Defense forces detected Dogora, but it was a swarm of bees. The bees flew into a cloud, and dozens of multiple-colored rocks fell out. Dogora was detected again as he attacked Fukuoka. He began to feed on coal and diamonds, but was confronted by the J.S.D.F., where he was blown to bits by missiles, but not before hurling a bridge at the humans in an attempt to ward them off. The pieces of Dogora regrew into their own cells, and attacked again. It was discovered that Dogora was weak to wasp and bee venom, as it's cells turn hard from it. Helicopters released venom on top of the Dogoras, causing them to harden and die.

Godzilla Island
This kid-friendly Japanese TV show was known for its use of plush toys and action figures of famous kaiju to in the portraying of the exploits of Toho's famous kaiju universe. Dogora makes an appearance on one episode being an evil spawn of the Xiliens.

Abilities
Dogora can fly, even when carrying objects of extreme mass.
Dogora has tentacles which it can use to attack or grasp objects, which it can then use to attack.
Dogora's body has a corrosive effect.
Dogora is able to work like a vacuum and suck up needed minerals if their body is divided.
Each piece of Dogora will take on a life of its own and can grow into a mature Dogora.
Weakness
Bee and wasp venom is lethal to the Dogora and will cause their bodies to solidify.

Trivia
Dogora's roar was reused for Ultraman's 4th dimensional enemy, Bullton.
For scenes of it in its full form, the Dogora prop was placed in a small vat of water and puppeteered by people holding wires. This gave it the impression of it floating like an airborne squid.
​The film is unusual for Toho's giant monster series in that the creature is non-anthropomorphic and not presented by an actor in a costume.
There were originally plans to feature Robert Dunham in a series of films based on the "Mark Jackson" character he played in this film. However, those plans never came to fruition.

Film
Dogara, the Space Monster, released in Japan as Uchū Daikaijū Dogora (宇宙大怪獣ドゴラ, lit. "Giant Space Monster Dogora"), is a 1964 Japanese tokusatsu science fiction film produced and released by Toho Studios. Directed by Ishirō Honda and featuring special effects by Eiji Tsuburaya, the film starred Nobuo Nakamura, Akiko Wakabayashi, and Hollywood actor Robert Dunham. The film tells the story of a huge jellyfish-like creature from space that attacks Japan.

The film was released straight to television in the United States, in the Winter of 1966 by American International Television as Dagora, the Space Monster.

Plot
When several TV satellites launched by the Electric Wave Laboratory go missing above Japan in Earth's orbit, it is found out that they have inadvertently collided with unidentified protoplasmic "space cells" of unknown origin. A similar creature suddenly thwarted the efforts of a local branch of the International Diamond Robbery Ring. The diamonds they sought vanished, and similar unexplained events continued to occur across the globe.

Meanwhile, Inspector Komai's (Yosuke Natsuki) investigation of these strange events led him to the crystallographer Dr. Munakata (Nobuo Nakamura). In the process of tracking down the self proclaimed diamond broker Mark Jackson (Robert Dunham). He finds him in Dr. Munakata's home but knocks him out and escapes from Komai. He is then picked up by the gangsters for questioning. Komai wakes up and is greeted by Dr. Munakata and his lab assistant Masayo Kirino (Yoko Fujiyama). He tells them about the case he is working on and shows them pictures of the melted safe the gangsters were at that night. Komai then learns that the diamonds the Mark stole were synthetic and worth nothing.

The gangsters bring Mark Jackson to there boss and find a bang containing the stolen diamonds. However they too find out that they are fake and keep him as a prisoner but out wits them and escapes. The gangsters are then given word of a shipment of raw diamonds will arrive in Yokohama.

Meanwhile, Inspector Komai escorts Masayo to her home. Along the way they meet Kirino (Hiroshi Koizumi), Masayo's brother who works at the Electric Wave Laboratory. They witness a strange invisible force suck up coal into the sky from a nearby the factory as well as flaming sparks from the clouds. They meet back with Dr Munakata who tells them that the flaming sparks might be from some form of carbon.

​Later, the professional thieves took advantage of this ripe opportunity and attempted a heist on an armored car carrying the raw diamonds. But a nearby coal truck passing by is lift off the ground by some unknown force and disappear into the atmosphere and is dropped back down to the ground. Unfortunately for them, they were fooled and escaped with nothing but candy.

The police came to learn of the mysterious events of the armored car heist. Inspector Komai tells them of the possibility of a creature that caused the coal truck to list up in the air, but no one believes him. He is then called by Masayo a that Mark Jackson is at Dr. Munakata's house. Komai and the police surround the house to catch him. But he revels himself that he is an investigator dispatched from the World Diamond Insurgence association to find out what has been steeling diamonds world wide. Just then Masayo's brother comes in and tells them that the identity of the monster was reports from the Space Planning Committee at the U.N. that the monster is a space cell that's been mutated by massive amounts of radiation from the satellites. Suddenly, Dogora appears and eats it's way though Dr. Muanakata's safe to eat the diamonds inside.

The creature from outer space is deemed to be the culprit, an alien beast that draws its energy from carbon based minerals. Dr. Munakata, confident in a remarkable scientific discovery, left for the coal mines near northern Kyushu, where it was proposed that the strange being would make its next appearance.

Mark Jackson also took leave for Kyushu, as the realization was finally made that the candy recovered at the heist was likely his doing. It was probable that he had, in truth, absconded with the true gems. Hamako (Akiko Wakabayashi), one of the gangsters responsible for the failed heist, prepared to double-cross her comrades and retrieve the diamonds for herself.

As Dr. Munakata arrived at Dogora's next likely target, unidentified objects began to show on radar. A swarm of wasps was attacking Dogora in retaliation for the disturbance of their hives in the mines, and as they attacked, solid crystal sections of the monster began to fall to the city below.

Over Dokaiwan Bay, as night fell, evacuation orders were put into effect as the jellyfish-like monster began to descend from the sky. The self-defense force fired, to no avail. The monster continued to absorb carbon-based materials wherever they could be located, and the abomination even destroyed the Wakato Bridge in the process. The military continued to unleash their artillery at the alien creature, and succeeded in momentarily silencing their foe. Unfortunately, the creature was only undergoing mitosis.

​It is later found out that when Dogora is stung by the wasps, the venom causes a chemical reaction that crystlises the space cell. Analysis of the crystallizing effects of the wasp venom on Dogora at the Medical Substance Laboratory proves successful, and mass production was soon ordered all around the world for the creation of a similar toxin.

The gangsters, still desperate for a successful heist, tracked Mark Jackson and Inspector Komai and almost immediately jumped to the conclusion that Mark had hidden the real diamonds in a safe-deposit box. Hamako left to retrieve the stash, but instead fled solo with the stolen goods. The thieves left Jackson and Komai tied and doomed to death-by-dynamite, but the two men joined forces and only barely managed to escape.

Meanwhile, Dogora attacked once again, but this time, powerful artificial wasp venom quickly ate away at the creature. The robbers and the police clashed at the beach, and in the heat of a vicious gunfight, the gang was completely wiped out by a falling crystal boulder, once a section of Dogora's extra-terrestrial flesh.

The wasp venom finally took full effect, and Dogora was no more. It was soon discovered that the diamonds Hamako had retrieved from the safe-deposit box were, in fact, synthetic. As this truth came to light, Dr. Munakata and his secretary left for the UN to discuss the peaceful potential of the Dogora incident with the world.
