Sugata is a young rich man who is betrothed to Wako. He is the master of his family martial arts. He is cool and intellectual, and seems to keep his sadness to himself. He's the candidate to inherit the power of the King Cybody. As a candidate to inherit the power of King Cybody, he's not allowed to leave the island. He hates his own birthday because, on his birthday five years ago, his father told him about his destiny to be bound with the King Cybody power. He is resentful of his fate. His first phase power, the King's Pillar, is so powerful that he falls into a coma after using it to save Wako and the others. He eventually wakes up from coma in Episode 7 but, unfortunately, Scarlett Kiss has used her charming kiss power to manipulate him. However, Sugata managed to break from Scarlett Kiss' control and take over her Peshent to test whether Takuto is worthy enough to protect Wako. After the fight, both of them seem to come into an understanding. From then on, Sugata trains Takuto to be prepared for battle. Recently, Sugata seems interested in Head's painting and often visits him to know the progress of the painting. Meanwhile, Head takes this opportunity to get closer to him.

She is also the president of Southern Cross High School Science club and often does experiments, sometimes using students as lab rats, as seen with Tiger. She is the leader of third division of Crux Brigade, Bouganveila. Her alias is Ivrogne. She was childhood friend of Wako and Sugata. They also once built a totem pole in the past. She is the east maiden of the island. It is later revealed that Keito has been in love with Sugata since they were kids.
Age: 21 "Twilight" Suzuka is a female Ultra Class A assassin who only kills when the sun is setting. Her preferred weapon of choice is a bokken, or wooden sword, which through secret, semi-mystical swordplay can be used to slice metal like a cleaver and smash concrete, yet on the next stroke will land only a knockout blow on her opponent. She first appears when she tries to kill Gene Starwind's friend Fred Luo as part of her contract with a rival weapons seller. Gene is able to outsmart her and force her to consent to come after him before she kills Fred as part of her pride. However, in her next appearance, Suzuka saves Melfina from a Kei Pirate and decides to help the group against the Kei Pirates, mainly to go after a member of the Anten Seven named Hitoriga, who killed her family. Surprisingly, Suzuka seems to know more about the Kei Pirates than the rest of the crew. Among the various members on Gene’s ship, Suzuka could best be considered the lone wolf, relying very little on outside help to accomplish her goals and frequently disappearing at ports to take care of "business." She is quiet and pensive, and once tells Gene that she 'sticks around' only because she finds him interesting, much to his chagrin. Much about Suzuka's past is unknown, such as why the Kei pirates would target her family, how she survived, and who trained her or if she trained herself. Even her age is never really mentioned during the run of the series. All that is known is that her pursuit of the Kei Pirates is of personal nature, particularly towards the assassin Hitoraga, who murdered her clan and family. Near the ending of the series, it is implied that she has feelings for Gene. During her fight with Hitoriga, he asked her, "Why are you following this man? Don't tell me you love him." She responded by telling him that he would hear the answer if he defeated her, which ended with Suzuka being the winner. So the nature of her feelings for him has been left unresolved.
Aisha Clanclan belongs to one of the noble houses of the Ctarl-Ctarl Empire. From a young age, she excelled in her classes...but the highest honor in Ctarl-Ctarl society is to go into space. Finally, Aisha won her place in space when she was promoted to the rank of Ambassador Plenipotentiary and given command of the Orta Honehone. But then, as her ship was on its way to Blue Heaven, Aisha got caught in in the middle of an Outlaw chase. Hilda's ship, Horus, (with Gene, Jim, and Melfina inside with her) were trying to escape from several other Outlaws (hired by the MacDougalls)...and the Orta Honehone was in the way! Aisha tried to throw the weight of the Empire by demanding the ships get out of the way, but she didn't realize that Outlaws answer to no one but themselves. Aisha had to order the ship to move aside so Horus could get past...but when a small asteroid hit the ship, she got angry and gave the order to fire. Though she would eventually capture the pursuing Outlaws, Hilda and company got clean away. When word of the fiasco reaches the home planet, Aisha is stripped of her rank and reassigned to Blue Heaven to gather information on the Galactic Leyline. Dejected, Aisha wandered the space colony. Then, when Gene returned, she learned that he knew Hilda, and she confronted him, chasing him all around with Ctarl-Ctarl ferocity and relentlessness...until she ran out of energy. Hoping to learn more about the Leyline, Gene takes her to dinner, and before Aisha can turn the tables on them, Gene KO's her and leaves her with the bill. Aisha doesn't catch up again until the Heifong Space Race, where she commandeers a passing Ctarl-Ctarl patrol vessel and pursues Gene all throughout the race. Eventually, Aisha learns that Gene is looking for the Galactic Leyline, so she happily makes herself part of the Outlaw Star's crew. As Jim described them once, the Ctarl-Ctarl are sort of a cross between a human and a tiger. Aisha, typical of her race, is very proud, very direct, very aggressive...and very tough. Few things faze a Ctarl-Ctarl (surviving a #12 at point-blank proved her point on that account). Even in humanoid form, they are much stronger than most other races, and they have high tolerances for extremes (for example, she doesn't consider hot springs hot unless the water's boiling). Things gets even worse when they need to morph into their beast forms, where their awesome power is magnified even more and can be further boosted by the light of a moon. The only problem with the beast form is that it's hypermetabolic, allowing only a brief period of transformation...and requiring a healthy meal afterwards to recoup the lost calories.
He was a young man who developed a fear of space flight and a hatred of pirates during an attack when he was 15 that resulted in his father's death at the hands of a band of mercenaries led by Ron MacDougall. Gene was thrown into an escape pod by his father moments before their ship exploded and landed on Sentinel III where he would remain until the beginning of the series. Until Hilda questions him, "Are you going to keep running away?" and Gene responds, "Keep running away?" Gene is scared of space—but Hilda's questioning of his courage is the turning point, and Gene's fear of space disappears. While on Sentinel III, Gene met the much younger Jim Hawking and the two went into business; forming a company called Starwind and Hawking Enterprises. Gene is a reckless ladies' man and a bit of a pervert who shamelessly flirts with almost every woman he meets. He would rather try to achieve his goals with a minimum of effort and his reckless attitude proves a continuous source of frustration to Jim. Despite his brash nature, Gene does have a caring side to his personality which he usually displays toward Melfina. After realizing Melfina had no recollection of her past or function, Gene promises to help her find her past and protects her from the various individuals in pursuit of her. Also, throughout the course of the series, he begins to develop feelings for her, and grows rather irritated with Harry on behalf of his apparent relationship with Melfina.
DoroDoron is the third of the Dark Fall to attack Earth after Moerumba fails. He's an arachnid-alike creature that travels underground instead of through the air. DoroDoron transforms earth-related objects such as rocks and cobblestones into Uzainaa monsters. He also occasionally takes commands from two suspicious girls (Kaoru Kiryuu and Michiru Kiryuu) that are in the same class as Mai and Saki. His name comes from the word "doro" which means "mud" in Japanese. Source Wikipedia
