Marblegen

Cosmo, Sam, and Luna, are mega fans of a game of magic marbles: the Marblegens. They meet Aïssa, unbeatable on the rules and fine strategist. The young friends discover that this year, the winner of the Marblegens Tournament will win the legendary Marble Origin Mercury!

Cosmo, Aïssa, Sam and Luna decide to prevent Marcellus King from getting his hands on the Marble Origin: they create the team of Meteors and try to register for the tournament. But for that, they need marbles, and not just any: real Marblegens!

When an alchemical incident in the Lab creates a spatial loop, the Meteors are prisoners in the Observatory! Stalked by a giant spider who wants to catch them in her web, they will have to find a solution before Miss Drex shows up for a routine visit to their Arena.

Cosmos borrowed the Costello's Spell Book, despite Zumeo's interdiction. Archi and Lardo manage to steal it. The Meteors have to retrieve the book at King's Corp and get back on time to play their match against the Crimson Knights.

The Meteors learn that when Zumeo was young he and Gaia Fulmina, the Olympian alchemist, were snipers on the same team! Their collaboration ended after an illegal clandestine Ultimate Battle in which a marble was stolen from them, by two archeologists have just turned up in Olympia after dinosaur bones were discovered!

A shopkeeper offers Luna a product with exceptional properties (the mythic Uroboros fangs)! But Zumeo warns her that she isn't old enough nor experienced enough to use this product. The shopkeeper discreetly gives Luna a sample which Luna uses to create formidable "serpent marbles".

Aissa has to participate in a dance audition on the day of a big match. What at first seems complicated but doable becomes a problem when the time of the audition is changed to take place at the same time as the match. King apparently has something to do with this complication.

A sports clothes brand wants to make Cosmo its new icon. Cosmo loves the idea. Seduced by the glitter and gold of fame, he cuts off ties with Remus (who sulks because the young Sniper wants to use him in a stupid advertisement), blows off practice, yells at his friends and basically gets himself into a hornet's nest in which Marcellus King is no stranger.

The Mirages have apparently gotten their hands on a powerful creature Marblegen, Charybdis, which draws all opposing creature marbles to it and swallows them whole. The Meteors panic. The upcoming match seems in even more dire straits because Cosmo, goofing around with Luna's alchemy supplies, accidentally rubs his eyes with his hands covered with a powder that seriously hinders his vision!

A mysterious team made up of a single masked sniper-alchemist - Unik - takes on the Meteors. At the same time, Cosmo has a crush on Lucile, who is very interested in their training sessions.. Sam investigates to learn about Unik and discovers the Lucile and the masked sniper are one and the same! Cosmo was betrayed and has a hard time accepting it, but there's a match to play and win!

During a match against the Meteors, the Shadows play CHRONOS, a Marblegen that rewinds time if they're losing a match. Having activated Romulus' protective powers, Aissa remembers the past and discovers that she has gone back in time. She will re-live the same day several times. And it happens that today is her birthday, which unfortunately always ends in disaster!

Our heroes take on the Druids, who use plant marbles with the terrific powers of flowers and plants! Tempted by easy solutions, the Meteors search for a miracle marble that will guarantee a victory without having to study or practice. Zumeo tells them about Califerax, the crop-devastating locust marble that Idriss, a friend of his, can loan them.

The Meteors face the Werewolves and their terrifying marble LYCAN. Moreover, they have to play on the night of a full moon. The Marblegens' energy is such that, during a Battle Royale, the battle between Remus and Lycan triggers an explosion that damages the arena.

Cosmo foolishly uses Lethe, a marble that makes you lose your memory, which Zumeo wanted to use to forget the shame of losing Mercury. He has to get his memory back before their match against the Bombeks and especially before nightfall or else his amnesia will become permanent!!

Bombi has tracked down Cosmo and Sam. He steals the Gemini astroset and demands that Cosmo and Sam come home to play the clandestine matches that made him rich in the past. Cosmo agrees; they absolutely have to get Remus and Romulus back!

Romulus has been destroyed! It's a tragedy! But there might be a chance to rebuild it... Zumeo leads Cosmo and Aissa into the secret sub-basements of the Observatory to search for the missing ingredient which made it possible to create the twin Marblegens many years ago, a piece of a Meteorite!

The Meteors take on the Fizzinis, a "circus" style team, during a very acrobatic Parkour Battle with certain shooting areas very high in the air. The problem is that Cosmo suffers vertigo and tries to hide his handicap. But in order to find the recipe for an adjustment for Lyncis, Luna leads the Meteors to meet an old alchemist, a hermit living on the cliffs above Olympia.

When she finds an old family recipe for Bellatrix, Luna starts making the marble. But the alchemist for the team the Meteors play next, the Valkyries, is also making the same recipe! Zumeo points out that both recipes are identical and yet authentic. WHO is the legitimate owner?? While waiting to answer this question, the two teams compete to gather the ingredients needed to make the Marblegen

Zumeo has gotten his hands on Vulcan, a Marblegen capable of jeopardizing all-powerful Jupiter and the Marbletechs. To prevent the Meteors from using Vulcan during the next match against the Monarks, King sends Kali to steal the marble...but he finds a stratagem so she isn't found out: thanks to a Marblegen, Kali and Aissa exchange bodies!!

Sam wants to play at apprentice alchemist but he keeps making mistakes! When Luna loses confidence in him and rejects him, he meets the alchemist of their opponents, the Storytellers, who has him touch a mysterious marble. From this moment, the Observatory laboratory is sabotaged several times at night.

When she wants to create Mesarthim to complete the Aries Astroset, Luna forgets to watch the temperature of the Marblemachine, which implodes. Without the Marblemachine, the tournament if finished. They have to find a replacement part, the Athanor, the main part! But King, who catches wind of the incident, sends his henchmen to scoop up all of the Athanors in the Market.

In his Marblegen collection, King possesses Quetzalcoatl (one of the ultimate Mayan gods, capable of capturing the soul of Spirits/Creatures in his lair!). In order to deal the kiss of death to the Meteors, Kali steals this ancient marble and activates it during the battle. The god goes wild and kidnaps Romulus to take him to the ETHER world with Cosmo and Kali!

The Meteors match against the Tsareviches is interrupted when Baba the Alchemist (100 years old!) faints. The match is postponed and Baba goes home to rest. But her pet hen, Zorya, suddenly comes to find Sam at the Observatory in a panic, and the Meteors discover that the Tsareviches have been burglarized.

The Meteors have a match officiated by Jack Snake, a new referee, who causes them to lose with unfair decisions! But where is Harry Cup? Why isn't he working the tournament anymore?! Sam investigates and discovers that Snake tricked Harry Cup to become the main the referee of the tournament: he stole his voice with a VOODOO ritual!

Aïssa, Cosmo and the Olympian Snipers try to capture Phobos, a terrifying marble. But the Creature leads them into a parallel world where they have to confront their biggest fears. And in this world, King has won Mercury and controls Olympia! The 4 Snipers live their worst nightmares one after another until Phobos chooses the perfect Sniper among them: a fearless Sniper!
