Venusian (Supersonic Saucer)

Venusians are a race of aliens living on the planet Venus in the 1956 children's film, Supersonic Saucer. Although only the young Venusians are seen, they are shown to possess psychic abilities and be able to shape-shift, with one Venusian child in particular - a male nicknamed "Meba" - ending up paying a visit to Earth and having an adventure with a trio of children from a boarding school.

Biology
Although only the young Venusians are seen, they are diminutive beings that resemble a featherless owl/penguin wearing a white niqab - although one of the children describes them as looking like "Amoeba Proteus". They have large eyes and appear to have no mouth, so it's unknown what they eat on Venus as they cannot eat human food. They are shown as been intelligent, as evidenced with Meba been able to read English and learn how to find places/use human devices along with been able to use strategy to overcome a situation.

In terms of their abilities, the Venusians are capable of psychic powers including telepathy - of which they can communicate with others using both words and pictures, and during which they make a make a whirring/humming noise - as well as telekinesis and pyrokinesis. They are also capable of rewinding time to affect certain people or animals - during which their eyes spin wildly. Most notably, the young Venusians are taught by the adults to shape-shift into a form resembling a flying saucer, which grants them not only the ability to fly at great speed but the ability to travel between planets. Their shape-shifting also allows them to get through narrow holes and openings without any issue.

Finally, while in their flying saucer form they can transport large amounts of objects from one location to another - as evidenced with Meba been able to carry various loads on separate occasions.

Personality
While only Meba is focused on in the film, it's clear that the Venusians do possess emotions. Meba explains during a flashback when he was struggling to transform to a flying saucer form that his friends (who had all mastered it) making fun of him for not been able to shape-shift.

Meba displayed a curious interest about Earth and humanity, while also showing affection to the children he befriends and trying to make them happy when he heard them casually wish for things. However, been unfamiliar with Earth customs and due to taking what the children said literally, his attempts to please the children would often backfire. He can also be pretty blunt at times to the point of potentially being offensive, as he refers to one of the children as "the one with the goggle eyes", referring to the fact that the boy is wearing glasses.

Meba was shown to get upset when his attempts to please the children failed, which included him crying as a result. He was also naive as he openly believed the word of a criminal despite having never communicated with the man before, which led to him getting captured. However, he was shown as been clever and able to create and use strategy - especially regarding how he helped to save the children from the criminals and get the attention of the authorities.

History
On the planet Venus, a group of Venusian children were been taught how to shape-shift into a flying saucer form. While each member of the group soon worked out how to do it, one of the group - a young male - was proving able to spin but not to transform, with the rest of the group who had managed to do it making fun of him for his struggles as they flew around him. After they left, the male continued trying - finally figuring it out. Ecstatic about finally managing to transform, the male began to zoom around in his saucer form - his excitement leading him to flying around Venus and out into space. When he finally came to his senses, he found himself far from Venus but very close to Earth, with a curiosity to explore the planet and learn more about the 'humans' who lived there compelling the youngster to travel to Earth.

Sure enough, the young Venusian headed towards England - flying over London and eventually coming to a stop in a tree near the boarding school, which was mostly devoid of pupils due to the summer holidays. His landing was heard and witnessed by the School's Janitor (secretly a member of a gang of criminals), who proceeded to leave but kept what he'd saw secret for the time being. The others who heard and witnessed the Venusian's landing were a pair of girls from the school - Greta and Sumac - who had been unable to go home for the holidays and calmly approached the diminutive alien before talking to it; discovering that the alien could speak to them telepathically as it explained that it was from Venus and had come to Earth to see what humans were like. After showing off its ability to rewind time when it made Juno - a dog that was running towards him and the girls - run backwards, the girls decided to show the alien to their schoolmate Rodney, who was the son of the Boarding School's Headmaster and had a keen interest in science.

Rodney's opinion of the alien is that it looked like an amoeba - specifically "Amoeba Proteus", with the girls suggesting they called the Venusian "Meba". "Meba" himself approves of the name and states he would prefer to talk to Greta and Sumac as he finds Rodney to be hard to understand - referring to Rodney as "the one with the goggle-eyes". When asked about why he came to Earth, Meba shows Sumac a telepathic vision which explains about how young Venusians learn how to shape-shift, his initial struggles with it and eventually his success and flight through space - with Rodney stating that when the school had gone to the observatory for a school trip before the summer holidays the day before, he'd seen Meba as a flying saucer when he looked at Venus through the observatory's telescope, even though no-one believed him. Meba also explains that he intends to stay on Earth for a day or two to rest before making the journey back to Venus.

When the children complained about having a dull supper and wishing they had various sweet items like toffee, cake and ice cream, Meba took what they said literally - not realizing that the children weren't been serious but seeking to please his new friends anyway as he transformed into his flying saucer form before flying out of the window. After flying over London for a while, he came across a cake shop called "Dutch Oven Teas" and entered - taking a large number of cakes and buns back for the children. The children were initially thankful, but quickly realized that Meba must have stolen them from somewhere; telling Meba (who admitted to taking them but said they were 'borrowed') to take the cakes and buns, along with money from the children for the buns they had started eating. Meba complied and returned the items back to the shop before returning - although he ended causing another problem when he heard Rodney wish about having a fire instead of radiators; using his power to set several items on fire.

Although Meba soon extinguished the fires when the children told him to and reversed the damage the fires he had created caused, he began crying - stating to the children that he found them difficult to understand as he only wanted to please them but when they wish for things, they no longer want them when he provides them - with Sumac and Greta apologizing and promising to be more careful when they wish for things. When Meba began shivering due to also feeling the cold of the night air, the girls put a sweater on Meba to keep him warm and take him to their room for bed, tucking him into a dolls bed for the night. Later in the night, Meba is awoken by the girls - who both are upset that they couldn't go home for the summer holidays as Greta's parents are in Norway and Sumac's parents are in South America. While talking about how much it costs to go to either country, the girls suggest they'd have to rob a bank to get the money they'd need for both of them to go home as they theorize that there must be a million pounds in a bank - along with how goo dit would be to have that much money.

Once again taking what he'd heard literally, Meba transformed into his flying saucer form and headed out into the night - flying around and above London until he found the bank. After sneaking inside, he managed to get inside the vault and successfully steal a million pounds before returning it to the Boarding School.
