Scrameustache
[1] The story tells of how Khena, a young Peruvian boy living in Europe, meets a cat-like alien who has come to Earth in his own flying saucer.
Khena lives with his adoptive father Uncle Georges in the small town of Chambon-Les-Roses and the Scrameustache moves in with them.
Some ten years later, Khena met the Scrameustache and proved himself resistant to the alien's (non-lethal) weapons and other technology.
He does however remain a leading character, some of the stories looking at his development from a boy in his early teens to an actual teenager.
[1] However, in D'où viens-tu, Scrameustache, p. 12, it seems that Scrameustache is a backronym for Sujet Créé par Radiations Artificielles et Manipulations Extra-Utérines Sans Toucher Aux Chromosomes Héréditaires Endogènes (Subject created by artificial radiations and extra-uterine manipulations without touching to hereditary endogenic chromosomes).
In Le dilemme de Khéna (Khena's Dilemma), the young man indicates that George is descended from an aristocratic family called de la Roche (Roche being the French for "rock") Over the years, Gos has expanded the Scrameustache's universe, with him and Khena travelling to other planets and mixing with other aliens, above all the Galaxians.
Aktarka does not have cities like Earth, instead its human populations lives in towns and villages where each person has a bit of land to cultivate food.
It is hinted in later albums that the citizens of Aktarka are descendants of Atlantians who managed to flee before the destruction of their continent on Earth.
It is hinted that the Aktarkian leaders feared his superior intelligence would turn against them and thus sent him into some kind of unofficial exile.
The aerials on the helmet can be used for communicating or listening into radio-emitted conversations, but this requires a certain amount of concentration on the part of the wearer.
His flying saucer is for intergalactic exploration and, by applying theories and calculations based on faster-than-light travel, can go back in time.
Khena and the Scrameustache now spend much of their time travelling to Aktarka and other planets to visit friends and relatives.
Although a very decent man he is quick-tempered at times, and especially finds his son's alien friends a bit of a handful.
The annual head of state is called the Prince-of-the-Year and is the Galaxian who received the most merit points over the past year.
(From the early-1980s to the late-1990s, many one-page gags and short stories were published in Spirou magazine under the title Les Galaxiens, giving humorous descriptions of Galaxian society.
They discover a 'temple' with the story of the first colony ship of the Galaxians, having crash landed on the island due to the same reasons our friends are stuck.
However, an enemy had sabotaged their spaceship and, while testing it, they were sent to an unknown period of time and space leaving Gari behind.
Adjusting to life in another period of Earth's past (the European 16th Century), Torcal and his wife had two more children, son Thibaut and a daughter Berengere.
Khena knew that the local laws restricted families to two children each and used this in order to stay on Earth with Uncle Georges.
Falzar, the Wizard of the Great Bear (Ursa Major), is the nearest the Scrameustache has to a sworn enemy.
Falzar occasionally manages to break free of his imprisonment and gets up to all sorts of devilish plots, such as turning people into animals.
The Stixes, yellow-skinned with pointed heads, are, on the other hand, ingenious and conniving characters and it is they who come up with the plans that the Scrameustache and his friends have to face.
