During the Renaissance, Léonard is an inventor convinced that he is the greatest genius of his time. In his workshop, he constantly imagines new machines, inventions, and experiments, often far ahead of their era. To test them, he regularly relies on Basile, his lazy and unlucky apprentice, who inevitably becomes the first victim of his creations. Between anachronisms, scientific disasters, and absurd rivalries, the series humorously plays with the figure of Leonardo da Vinci and turns each new idea from the self-proclaimed “genius” into an experiment that rarely goes according to plan.

Album 14
Léonard was tired of his disciple and decided to replace him with his nephew Willbur. Poor Basile took the thing badly and seemed to decide to end his life. From the coast of our genius, the euphoria of the first minutes quickly disappeared when he realized that he lacked the malfeasances of his former disciple. Go hop, neither one nor two, things returned to order and Basile resumed his place. Our genius then began to build new inventions, such as fries, the gold making machine or the monorail. Basile was even more clumsy than ever. Will he not regret his choice?
Album 15
Basile is a good disciple, ready to do anything to serve science. His work consists mainly in testing all the crazy inventions of his master, Léonard. This is how he finds himself embroiled by a "photo shoot", sent on a flying chair in space or captured by cannibals...
Album 16
Léonard has a small problem: his disciple has chickenpox. He must find someone else to test his inventions, and unfortunately Mathurine refuses to take care of it.

This strange ship in the form of a beard will allow our two companions to discover life underground, to meet strange species...
Album 19
Léonard never makes a truce, not even at Christmas. This party is just an opportunity for the genius to offer his disciple the opportunity to test one of his new inventions: the jump to the elastic. New activity that is cruelly lacking in development...

Léonard is a genius, of course, but a bit burdensome. His noisy and devastating inventions do not really contribute to the peace of the village...

Except that Léonard had not anticipated such a success...

Album 31
Who will stop the Léonard de Turk and de Groot? Still as fanciful and uncontrollable, this Vinci spends his time persecuting his disciple Basile rather than giving birth to real probative inventions. Once it is not customary, this album sees the old bearded convoking the most mythical strokes of mallet and tromblon in order to shake the "disciplus simplex" that takes place for him to valorize. Let both track the "dodo", this mythical bird of Mauritius giving its title to this 31st volume, which the Master invents – let's say more precisely: tries to invent – vocal recognition, the intelligent textile fibre or horoscope. So many "new technologies" commented by the impavid and objective chat Raoul Chatigré.
Album 32
Basile is a good tester, very resistant. His master Léonard has done everything to him! Discover in this new opus, how he puzzled it, the chamboule, melts it, the tromblone, the cannon, the telescope, the mill, the flame, compresses it, makes it sweat... Let's hope that at least his inventions will revolutionize the daily lives of future generations!
Album 33
The 2003 Cuvée des trouvilles du Genie des Génies bears the number 33. You said 33? Is it serious, Doctor? We had warned Léonard, the Genie and Basile, his disciple, that it was dangerous to put the finger between the tree and the bark, especially if it is terrestrial. We had also told them that it was even less necessary to put it in the eye of the cyclone. But, it is not so much deaf than those who do not want to hear anything. Apart from that, apart from a journey in time that ends in prison, apart from the invention of the encyclopedia and the marriage agency, everything is not so bad in the universe of unbridled madness of the genius inventor. And it is not Raoul, the philosopher cat of the house, who will mial the opposite! Moreover, it is once again the deceiving opportunity to remember the true meaning of the word "Genie". At the strength of finding all super and hyper, even mega-genial, it is not even so hard to open up a bit of the truth that it is a bit of the essence of the fact that it is a bit of the essence of the fact of the fact of the fact of the fact that the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact is the fact of the fact is the fact of the fact is the fact of the fact of the fact is the fact of the fact of the fact is the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact is the fact of the fact of the fact of the fact of the fact of the fact is the fact of the fact of the fact of the fact of the fact of the fact of the fact is the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact is the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the fact of the
Album 34
Inventing and still inventing to never stop inventing, this is the only reason for Léonard's life, the most brilliant of the Genies. Sleeping and still sleeping to wake up as often as possible, this is the happiness to which Basile, his devoted disciple aspires. Follow all the adventures of the ingenious duo ...
Album 35
Leonard, the famous service genius, has obviously found LA parade... against the bobos of his disciple Basile: he invents health by the plants. If he no longer has any money, he gains by raising snails: the helicoculture that this is called! At the radius of his creations, we will add the longest pipe in the world, the translator of alien languages, the fight against the "POP". With this 35th album, we celebrate the 30 years of the creation of the character: happy birthday, dear Monsieur Léonard! (Birthday page, photos of the birthday party)
Album 36
What is more intelligent than a genius, was he supremely superior? Several geniuses, pardi. In this case, they will not be too four to help Léonard overcome the riddle on page 13, mysteriously absent from his grimoire. Neither one, nor two, here is Léonard and his faithful Basile en route to Venice, in search of the descendants of the author of the grimoire, all geniuses as it should be....
Album 37
Can we imagine Laurel without Hardy, or Bip Bip without the Coyote? Never to a daring close, Leonard has decided to break this absolute taboo of the comic duo by licenciant Basile, his faithful «Disciple». Like this, without notice! It must be said that the substitute has everything to please: he solves the equations as he breathes and finds himself the nephew of our favorite genius! Would the famous «Debout Disciple !» have finished resonating?
Album 38
There are no more seasons, my good genius! What are we going to become if the snow begins to melt at the end of January? To this question, the average pekin answers with an increase of shoulders. It is that is not Genius who wants! Leonard, for his part, has somewhat extrapolated and analyzed the thing to reach the following conclusion: global warming will go from bad to worse, until changing the face of the planet in the twenty-first century! Fortunately for us, poor inhabitants of the future, Leonard, Basil and their time-traveling machine are on the move. Let's laugh a little while waiting for the melting of the ice.
Album 39
After so many years in the shadow of genius, his disciple Basile decided to compete with him. Let's take care that the national lottery and the database are only the beginning of a fulcruming ascent that will prove to the world that the genius is transmitted by simple prolonged contact! Let fans reassure themselves: Leonard still has many other resources! He has also just created the real estate agency, transforming the (old) stone into gold! Turk and Groot are far from having finished with our favourite genius!
Album 40
It's been 35 years since we've been wondering why Basile, the Disciple, has stayed with Leonard. We know that now: to make a little pocket money, he sells the genius's inventions to brokers. This misunderstanding solved with great blows of tromblon, it's time for him to make up for the risks involved in any treasure hunt. At the local hospital, we rub our hands! As long as Bob de Groot and Turk are at the hands, doctors and nurses will not experience the crisis!
Album 41
The car is to the honor in this new album by Léonard who sees the Genie explore all the possibilities of the machine, starting with the journey through time. But a real genius has an eco-consciousness and Leonard is no exception to the rule! Besides the wind-up car, he has found a new concept: the auto-stop. Of course, Basile is designated guinea pig of this new experience, since it is necessary to list everything that can happen to a hitchhiker and an unlucky driver. Science is at this price... Our laugh too!
Album 42
As great as he may be, Leonard does not always measure the consequences of his inventions. His elixir of gigantism seemed an excellent idea at first glance... After all, it was a question of solving the thorny problem of hunger in the world. But, even the most brilliant inventor could not predict that the apple-test contained a worm of the most aggressive. To enlarge a bird to get rid of it, then to call upon Raoul Chatigré to solve the bird's question, is this really the best solution...?
Album 43
Léonard, his indispensable disciple, Mathurine and Raoul are tired of playing the wrong straighteners for all, of taking a full face and of constantly being rattled by brutes of all kinds. Léonard invents a mixture that gives a superhuman strength. He is now a Super-Hero... a Super Genius!
Album 44
Too many people ignore it... After inventing the bike, Léonard has also created the most famous cycling race: the Tour de France. In his genius, he has not forgotten anything about what makes him famous today: the impassable passes (except by the disciple), the caravan of the tour, the "Belgian pot"...
Album 45
A champion of all kinds of morning fat, the Disciple suddenly faces his worst nightmare: insomnia. Fortunately, he shares the dwelling of the greatest inventor of all time. Léonard will ingenuine himself to find the ultimate remedy for this widespread evil. At the risks and perils of his patient...
Album 46
Leonard is never short of inventiveness and always at the cutting edge of technology. This time, he invents 3D TV without glasses and of course it is Basile, his disciple, who once again serves as a guinea pig!
Album 47
Since gastronomy is an infinite source of invention and of how useful it is in everyday life, Léonard and his disciple could not neglect this field of experimentation! So they are engaged in fierce competition with the other candidates and especially with Mathurine who is already a step ahead of them. Who will therefore win the Master Genie competition?
Album 48
The continuation of the adventures of Leonardo da Vinci's caricature which invents the most incongruous machines and makes all kinds of experiments with his faithful Disciple.
Album 49
Be careful, Leonard pulls out the heavy artillery! Here he is at the head of his last invention: the army. Of which to set up once and for all this flemmard of disciple! And make him a good little soldier. He and the whole house have no choice but to stand at your attention. Fortunately, Mozzarella is there to make resistance...
Album 50
On the occasion of the 500th anniversary of the death of Léonard De Vinci, his alter ego in comics pays tribute to him. But a tribute to the way of Léonard, involving moult painful experiments for his disciple.
Album 51
The continuation of the adventures of Leonardo da Vinci's caricature and his faithful Disciple, who engage in all kinds of experiments. Here, they develop organized crime.
Album 52
If you don't know what to do for your next holiday, don't worry: Leonard has some great ideas! Starting with his invisible bridge in the heart of the Dolomites, printed in Pleoxiglas by a 3D Vinci. Then the Genius Rock Festival, of which he is designer and organizer. And even the space, thanks to the agency Space Léoliday?!? Suffice it to say that Basile is not ready to take off. So, he tries to become a realistic comic hero in the company of a certain... Ric Hochet!
Album 53
Did you know that? It was a time – which the under eighty years cannot know – where Leonard's heart vibrates for another than Science. But the fate and father of Giovanna decided otherwise, and she married a banker rather than this strange jewel. Fortunately, patient in heart nothing impossible: Giovanna is now widowed and orphaned. It is therefore time for our Genius to seriously tackle the deepest of mysteries: Love!
Album 54
Will the heading of the 54th album be the one that will see Leonard become a genius of evil? After all, he travels through time, manipulates firearms and has a cohort of robots... What nenni! Our mad scientist potential has decided to take over, and to concentrate on inventions all that is quieter, like futon or female football. And the world of breathing: once again, Leonard's only victim will be Basil, because the service of science is at this price!
Album 55
After 54 albums, it had to happen: Basile makes us a little depressed! He still serves science, but where is the joy? Fortunately, eager to save Mozzarella from boredom, Léonard had a great idea that is worth all the antidepressants in the world: the circus! Take pies, blows, face fawns or amuse the gallery – all in joy – that, Basile, he knows how to do. It's even a genius in the matter!
Volume 56 — Flash of Genius
Basile makes us a little depressed! He still serves science, but where is the joy? Fortunately, eager to save Mozzarella from boredom, Léonard had a great idea that is worth all the antidepressants of the world: the circus! Taking pies, beatings, facing fawns or amusing the gallery? All in joy? That, Basile, he knows how to do. He is even a genius in this matter!
Volume 57 — Brilliantly Yours!
Will the heading of the 57th album mark the end of Basil's patience? This time, the indefatigable disciple decides to strike! But Leonard is not the kind to be stopped?: he deploys all his ingenuity to prevent his disciple from resting, multiplying inventions and creating new robots to assist him in his daily tasks. Never short of ideas, the genius will even found the order of the Leonardins, bringing together inventive minds in a monastery, where science reigns in master. At the end of these turbulent adventures, Basil will reveal an unexpected secret about Léonard, upsetting everything that was thought to be known about genius...
