• Blake Myers (
Julien Crampon in French and
Robbie Daymond in English) — Blake is a 13-year-old boy who dreams to become a space ranger and is a fan of
extreme sports. He is skilled at
parkour, which helps in escaping the Squaliens. He has a strong lack of sympathy for the self-centered and conceited Leonard and often uses questionable methods to defeat him, which does not please the latter at all. • Mitch de la Cruz (
Emmanuel Garijo in French and
Spike Spencer in English) — Blake's
Mexican American best friend who cherishes nothing more than their friendship and gets a little jealous whenever Blake's attention is diverted to someone else (but he tries hard not to show it or his envy at his fate). Mitch is a genius — but he sometimes struggles to stay focused. He loves inventing gadgets to help his best friend fight the Squaliens. If the Squaliens want to catch Blake, they'll have to face Mitch first! • Maxus (
Marital Le Minoux in French and John Fisher in English) — The bossiest, shortest and sometimes-greediest of the Squalien trio, Jerome's older brother and the General's nephew. At first glance, Maxus may seem like a fool, but if you scratch past the surface, you'll find a true technological genius. The General refers to him as the "team leader", even though it's actually Leonard; Maxus also seems to have tried and claim Leonard's title as leader several times. • Jerome (Emmanuel Garijo in French and Danny Katiana in English) — The jovial, carefree, absent-minded, polite and helpful dimwit of the Squalien trio who is Maxus' younger brother and the General's nephew. Jerome does his best not to offend anyone. He often falls in love with inanimate objects (dolls, stuffed animals, chess pieces, even bedside lamps or trash cans), and is mocked for being too kind or for his somewhat silly attitude. But beneath his easygoing exterior, Jerome is actually very intelligent: he is the one who has the most knowledge about humans. He is also the only one who seems to have an interest in Earth's flora and fauna, often bringing plants and insects back to the Squalien base to study them and, possibly, use them against Blake by genetically modifying them. The General calls him the "heart"; indeed, Jerome is often the buffer between Leonard and Maxus. When he makes long speeches, his voice changes slightly. • Leonard (
Jérémy Prévost in French and Kevin Glikmann in English) — The jaded genius and self-appointed leader of the Squalien trio with only one goal in mind: to capture Blake Myers. He is always the one who invents the gadgets necessary for their missions. Leonard sees himself as a great evil genius; solitary and ingenious, he would surely have already caught Blake a long time ago if he were not accompanied by the two worst teammates imaginable: Maxus and Jerome, the General's idiotic and clumsy nephews. Leonard is determined to catch Blake before he becomes a space ranger at all costs. Leonard gradually turns out to be an expert in prestidigitation, and so at the end of the series, he does not accompany the General and his nephews who thought they had taken him once they're sent back into space, instead managing to escape and stay on Earth to capture Blake all by himself as he follows the boy home, ending the show on a
cliffhanger. • Squalien General (
Philippe Catoire in French and Kevin Glikmann in English) — The Squaliens' commander who sent Leonard, Jerome and Maxus from the future to apprehend Blake. Although Leonard is the ace of the team, as Maxus and Jerome's uncle, he mostly takes their side and doubts Leonard, calling him the "weak link" of the three. He always finds his nephews Maxus and Jerome the best because Leonard is not part of his family, and when they come up with a plan, he chooses his nephews' instead of the old method that Leonard loves: his trusty
burlap sack. When Leonard goes alone, or does something that, most of the time, he should do as a team, the General comes to criticize what he does, and he always blames Leonard when the mission fails. He calls himself the team's "strongman". • Zorka (
Emmanuel Curtil in French and Danny Katiana in English) — The resident Russian contractor, Roy's guardian, and Blake's neighbor. He always comes to help him when he's in need. He is the only character in the series who mentions his racial origins. • Skye Gunderson (Audrey Sablé in French and
Katie Leigh in English) — Blake's neighbor, as well as his love interest. She is strong, compassionate, a bit of a tomboy, and a budding photographer. She also volunteers as a dental nurse helping her father. • Roy Cronk (
Gérard Surugue in French and Faruk T. Jenkins in English) — The obnoxiously cranky neighbor whose nerves Blake and Mitch often get on, and Zorka's friend. He takes great pleasure in criticizing those around him, and usually gets around in a wheelchair, which he calls Miss Daisy, only occasionally walking. • Dale Myers (
Mark Lesser in French and Derek Dressler in English) — Blake's father, and co-owner of the family travel business, "Let's Travel!". • Darla Myers (Alexandra Garijo in French and Tarah Consoli in English) — Blake's mother, and co-owner of "Let's Travel!". • Rodrigo de la Cruz — Mitch's father who is also a skilled inventor. • Carmen de la Cruz (
Fily Keita in French and
Yeni Álvarez in English) — Mitch's mother who organizes the town's block parties. • Dr. Björn Gunderson (
Jérôme Pauwels in French) — Skye's father of Swedish descent, who is the resident dentist and, like her, has
gap teeth. He enjoys fixing other people's teeth and hates candy. This doesn't stop him from distributing candy to children in order to keep his business afloat. • Isabelle Gunderson — Skye's mother. • Sunshine Gunderson — Skye's baby sister. • Fast Eddy — Zorka's pet
miniature bull terrier that keeps protecting his lawn. • Wanda — A weasel, a space ranger, and Leonard's ex-girlfriend. Originally neutral, she joined the fight against the Squaliens after Leonard chose to join the squirrel army to fulfill his ambitions, abandoning her days before their wedding. Much later, she joins Blake and fights Leonard because he cheated during the traditional rope fight. Lithe and agile like a weasel, she trains Blake to help him become an effective space ranger. She finds potential in Blake's skills. ==Episodes==
