Main

• Mahad (voice: Tim Hamaguchi, performer: Julien Girbig) – Age 17. Mahad is full of life, a show off, likable, charming, full of himself and adventurous. When he was younger, he was always unhappy because he did not have a father and his mother was a lot like Lena. In pilot school, he was always in detention due to making extreme moves on the simulator. Though not a Seijin, his goal is to free his mother. Until that time, he will slug it out with the Sphere. Though young, Mahad is unequalled as a pilot of his father's ship the Hyperion and after him, he is the best pilot in all of Skyland. Though his younger sister, Lena, always insists Dahlia is "too old for him", Mahad keeps trying to convince Dahlia he's the guy for her. He has enormous, often misplaced, self-confidence. His weapon of choice is his boomerang.
• Lena (voice: Phoebe McAuley, performer: Christelle Ouvrard) – Age 12. Intelligent, reasonable, calm but determined, impetuous. When someone she loves is in danger, Lena is a very mature, and formidable, 12-year-old girl. She alternates between carefree playing and grim determination. Adventure is not an end in itself, only a necessary step along the way. Lena is a powerful Seijin, believed by Oslo to be the 'Lady of Light' from the prophecy. She has the powers of telekinesis and telepathy, as well as other abilities such as powering energy and creating energy bolts and balls, projecting memories, and remotely sensing the presence of things and people. She can even levitate herself to great heights, as seen during an aerial battle with Diwan in the episode Heart of the Arena. She is beginning to control her telekinesis, but it tires her quickly. She has still very little control over her telepathy.
• Aran Cortes (voice: Jack Langedijk, performer: Dominic Gould) – Age 37. Gruff, moody, severe and just, with a tendency to be blasé (but still a rebel deep down). He's aware of his responsibilities as "father figure" and protector of Puerto Angel. Often complains that he has no idea why he listens to "kids" (particularly Mahad and Lena). He tends to show his anger physically, often punching a wall or banging his fist on a console when frustrated. Cortes was part of the original Pirate Rebellion and knew Marcus Farrell "by reputation." His weapon of choice is a shotgun. In the English dub, he has a dubious Scottish accent. Despite wearing his uniform with the Pirate crest even when "off duty" in Puerto Angel, Cortes "personalizes" it with a Tartan instead of a belt. He knew Cheng's mother before she was supposedly killed, and seemed to have had a soft spot for her.
• Cheng (voice: Cameron Ansell, performer: Max Gruber and Emile Kaczorowski) – Age 12. Cheng, despite his incredible intellect, is really still a child. He loves to fool around: missions are like video games in the great outdoors and he loves to play practical jokes on people. He is a very good hacker. He'll do anything for attention, like speaking in rhymes. He also has a crush on Celia. Cortes is his foster father. His parents were Pirate scientists that he believes are deceased. He thinks his only living relative is his grandfather, Tybald Ye, a scientist who is truly on the Pirates' side but pretends to be a Sphere supporter. His weapon of choice is a laser bazooka.
• Dahlia (voice: Alyson Court, performer: Tadrina Hocking) – Age 20. She has moved into the world of adults but is nevertheless attracted to Mahad's rebellious and youthful spirit, as well as his love for freedom. She finds Mahad's arrogance both irritating and appealing, which sets an interesting tension between them. She seems to enjoy giving Mahad grief. In "Eye of the storm", she nearly kissed Mahad had Lena not saved them. She often acts "serious" in order to distinguish herself from the "kids" but she breaks down from time to time and shows her mischievous side. She is proud to fight alongside Cortes and protect the people of Puerto Angel. She is a valued member of the pirates. Her weapon of choice is an energy bow and arrow. Mahad and others who disobey her are often quick to see the sharp side of her tongue.
• Diwan (voice: Athena Karkanis, performer: Lena Kowksi) – Age 25. Female master of highly developed Seijin powers, but not at Oslo's level. Appointed by Oslo to personally capture Lena. She's bald and has a red tattoo above her left eye and eyeshadow on both. Currently, Diwan would do anything to show her devotion to Oslo, who treats her like garbage in return. She controls the Brigadiers. While she was a captive of the Pirates, Diwan tried to escape but was cast off in the groundless Skyland, despite Dahlia's attempts to save her.
• Marcus Farrell – Former leader of the Pirate Rebellion. He is the father of Mahad and Lena, partner to Mila. Back when he was Mahad's age, he stole water from the Sphere in broad daylight. Mila and Oslo were sent to capture him and Mila got to him first. He helped Mila to see what the Sphere truly is, and they ran away together. Through their combined efforts, they built up the rebellion in six years, posing a real threat to the Sphere. He mysteriously disappeared during an attack on the Sphere leaving the Pirate Rebellion in disarray. Mahad and Lena discover in episode 10 that he may have survived, and might be hiding on one of the last free blocks.
• Mila (voice: Alex Belcourt, performer: Julie Delaurenti) – Age 35. Mahad and Lena's mother. Kept in hiding on the Sphere Block, Babylonia, she appears rarely and always in a very symbolic way. Her children only discover her heroic past (from the Vector and Hailong Zalo) after she is abducted. She used to hide in ships like a little stowaway. She was taken to the Sphere Academy of her own free will. She was a highly gifted former student in the Guardian School, where she spent time with Oslo. On her first mission with Oslo, they were sent to capture Marcus Farrell. She got to him first. She chose to renounce her exceptionally strong paranormal powers, as well as many privileges, when she decided not to help the Sphere after seeing how terrible it was. After leaving, she met up with Marcus Farrell and they married. She gave birth to her son Mahad and was about to give birth to Lena when Marcus vanished, crippling the Pirate Rebellion. She knew Oslo would find her again, so Mila decided to go into hiding and raise her children as a Mansa farmer without using her powers. She is a complex mix of Mahad's indomitable personality and Lena's exceptional powers. She was saved by Mahad and Lena in Kharzem Fortress.
• Oslo (voice: Juan Chioran, performer: Simon Flossaut Masnay) – Age 35. Brother of Darius, Comes from Vandegaard, a Scandinavian block. Leader of the Guardians and Commander of the Sphere. He knew Mila back in the Sphere Academy. They were best friends, inseparable. On their first mission together, they were sent to capture Marcus Farrell. When he found Mila, he attempted to turn her to fulfill the Prophecy, rule all of Skyland and take control of the Sphere. After hearing that her daughter was far more powerful, he decided to capture Lena. Absolute master of his highly developed Seijin powers. Oslo is able to use his powers in the dark and light by keeping himself exposed to sunlight night and day. Mila said that being able to use his powers in the dark would destroy him from the inside. He is a rival to Marcus, in that Marcus "stole" Mila from him. He told Lena Marcus was alive but she found it hard to believe. It is slightly obvious that Oslo has strong feelings for Mila, though she does not for him.
• The Vector (voice: William Colgate, performer: Olivier Breuils) – Age 60. A very intelligent smart man. The Vector has always lived as a recluse and was almost never interested in the "practical" aspects of life. He is eccentric and often unaware of danger. He is often pensive, daydreaming and lost in his thoughts. He rarely leaves his lighthouse on Puerto Angel. He taught Lena how to use her powers. The Vector has mapped Skyland, though it is incomplete. He helped Mila escape the Sphere Academy.
• Wayan (voice: Milton Barnes, performer Pete Thias) – Age 30. Wayan is Cortes' First Lieutenant. He is an excellent marksman, capable of total concentration and self-mastery during a battle. Conversely, he is much less organized in real life. Although he is talkative, a joker and a great storyteller, his perpetual optimism does not detract from his mastery of weapons and inborn sense of adventure which he satisfies with his mountain climbing exploits. Sometimes it seems he's Cortes' kid brother that he never had. His weapon of choice is a Shock Blaster.

Supporting

• Alice is a recently graduated Guardian who crash-landed on Puerto Angel and was captured. She believed that the Sphere were the "good guys" and the pirates the "bad guys." She managed to escape by tricking Mahad — who was on guard duty — and hid in the Mosquito bay. When Mahad captured her, she promised not to tell the Sphere about their location but he did not trust her. Alice threw Mahad out an open door but used her powers to save him. Out of pity, he hid her in his closet. However, Lena discovered her during a block-wide search and, through a telepathic communion, Alice learned from Lena that she was wrong about the Sphere. With the help of Cheng who fixed her Patroller, they planned to have Alice find their mother. Suddenly, they were intercepted by Diwan, whom Alice tricked into allowing them to escape. Now a supporter of the pirates, Alice plans to tell the other Guardians the truth, wherever she is reassigned.
• Astrid – Astrid is the daughter of Max. She seems to be very close to her father, as she always calls him 'Daddy.' She seems to be close in age to Mahad, towards whom she displayed requited interest. When she learned that her Dad was not the famous Sean of Aragon, she went to the Sphere but ended up hostage.
• Celia is a young Seijin girl who was taken in by the Pirates. When the crew was captured, Lena helped Celia discover her powers to defeat Jelola and Artemis. On Puerto Angel, Lena was her teacher in her quest to unlock the full potential of her powers. Celia could not talk while captive. She may have a crush on Cheng, calling him cute.
• Christophe Cortes – Full name "Christophe Mendias Theodore Cortes". Cortes' older brother. He refuses to call him Cortes and calls him by his first name: Aran. He arrives at Puerto Angel in a Mosquito asking a favour from Cortes to help him get his damaged ship that's stuck in ice barriers in a Sphere zone. Christophe's ship is the Callisto, a 'sister' to the Saint Nazaire. After Cortes helps Christophe free the Callisto from the icebarriers, Lena reveals him in possession of exalarium which is only useful to the Sphere in anti-Seijen containment technology. Christophe claims that he was only to going to deliver the supposedly worthless metal to maintain the Sphere's confidence. Unfortunately, when the Sphere left by Diwan assaulted both frigates and the Saint Nazaire being low on power, Christophe pretended to meet with Diwan to discuss their surrender before self-destructing the Callisto. Afterwards, he managed to escape Sphere custody with the promise to reunite with his brother soon.
• Darius is Oslo's twin brother. Was born minutes after his brother and his existence prevented Oslo from gaining his full Seijin potential. Was banished for life on the Vandegaard block.
• Hailong Zalo is an elder Seijin and ruler of Ningxia. He used to know Mila. He was imprisoned in a room where light felt like an intruder. Yet his apprentice Lee rescued him. Unfortunately, while being ambushed by Diwan, Zalo physically transmitted to Lena a message from her mother. Currently, he is weak but he left Lee in charge of Ningxia.
• Jonah is a scientist who was hired by the Sphere to design an Anti-Seijin holding cell on the Monolith for a very special Seijin. However, he heard that he would be executed after the job was done, compelling him to escape. He was intercepted by the pirates who asked for his help to sneak Mahad and Lena onto the Monolith. Instead, he took off in the Hyperion but was captured by Diwan. After a series of fights on the Monoliths, Jonah escaped with Mahad and Lena so the Sphere could never use his genius. Jonah was seen in the episode "Infiltration."
• Lee comes from Ningxia, and apprentice to an old friend of the Vector, Hailong Zalo. He came to Puerto Angel in search of "Little Phoenix" (Lena) for his master had a message from her mother. He was dismayed when the Sphere had turned against Ningxia with the aid of fellow apprentice, Feng. He helped Mahad and Lena escape from the guards and enlists their aid to save his master. He made it look like he was following Feng's orders to capture them. Once he distracted the guards, he freed Mahad, Lena and Zalo. But, they were ambushed by Diwan. Lee went a little offscreen for a while. After Ningxia was freed, Zalo put him in charge to protect Ningxia if the Sphere returns.
• Max is father to Astrid, and was a delivery man to a famous but now dead scientist, Sean of Aragon. He pretended to be that scientist in order to impress his daughter, but was, in reality, little more than a con man. Pretending to be the Sean of Aragon brought nothing but trouble, however, as the Sphere wanted to find the scientist, who had been working on a formula for an endless source of water when his lab 'mysteriously' blew up.
• Patrucci is an extremely paranoid citizen of Puerto Angel, Patrucci lives in constant fear of the Sphere, and of betrayal from his fellow rebels. He does not trust Mahad and Lena, nor seemingly Cortes, although he displayed concern for Dahlia in 'Manipulations'. His character model is often recycled, but most fans agree that the 'true' Patrucci only appeared in 'Manipulations'. Though he wanted to leave, he reappeared in "Alice" who ratted to Cortes that Mahad, Cheng and Lena were helping a Guardian escape.
• Shinseiki is a Guardian student who was banished to the Fringes for her attempts to fulfill the Prophecy on her own. Even in exile, Shinseiki brooded from revenge. Using dark powers, she kidnapped several Seijins in order to absorb their powers to unify the blocks of Skyland and recreate Earth, no matter how many suffered. To this end, she telepathically reached out to Lena to bring her to the Great Wall and then to her tower. However, Lena tricked Shinseiki, overloading her with power and destroying her tower, but the mad Seijin had survived the blast. Shinseiki moves like a circus performer and has a small brigade of Brigadiers as escorts
• Tibald Yee is Cheng's grandfather. He lived in the time before Earth broke up. When it did, he joined the Sphere when it brought order to the chaos. His daughter and her husband were Pirate scientists. Tibald made every last scrap of the Sphere's technology, from the Brigadiers to the S-22 Patrollers to the Monolith. While delaying development on his missile defense system, Tibald dispatched Patrollers all over Skyland to find Cheng. When he succeeded, Diwan found out and arrested him as well as Mahad and Lena who came to rescue Cheng. When the Pirates arrived, he fought with Cortes, passing him the plans to his missile defense system, and they settled on a trade for him, for Cheng. He is now a supporter of the Pirates secretly.
