Male. Red hair and red eyes. 186cm. The leader of the Skeld, called Captain. He commands the team, leads from the front, is highly intelligent, and a great strategist. He loves ketchup and always carries it with him. He is a warm-hearted person who always wants to help those in need and is a reliable leader. Everyone except Yellow uses polite language toward him. His weapon is a pink lightsaber. Because of his important role as leader, he always stands at the vanguard and directs the crew members.

Male. Blue hair and navy eyes. 185cm. Possesses immense strength and serves as the team's mechanic. He is always full of ideas, bright, and cool. His weapon is a crackling electric Thor's Hammer that no one else could lift. He once used a hammer four times his body size as a temporary weapon. He is a bit of a gourmet, so he hates the Captain's mindless obsession with ketchup more than anything.

Male. Brown hair and brown eyes. 178cm. A bit of a klutz but a person Red trusts deeply. He often causes accidents but can be serious when it counts. He is a genius and a fool at the same time. If he burns through his life force by overusing his power, his body shrinks as a side effect. He is the textbook definition of a 'hidden ace' comedy character. Brown has a dust allergy. His weapon is a yellow lightsaber.

Male. Dark green hair and light green eyes. 177cm. He is extremely quick to grasp the situation and can fight even with just a stick. He is serious and smart but also a comedy character. He is in charge of communications for the team. His weapon is a blue lightsaber. His favorite food is chocolate ice cream, and he is allergic to strawberries.

Male. Black hair and black eyes. 176cm. He carries a small green alien named Bruni on his head, which can ignite flames. He is good at performing tricks and cherishes Bruni deeply. He is very innocent. His weapon is a laser gun, and he serves as the team's hacker. Bruni can shoot fire and is incredibly loyal.

Female. Turquoise hair and mint eyes. 164cm. Also known as Pulse. She is the team's scientist. She left the team to help Purple recover, and though she tried her best to save her, she failed and had to use Sentinel Program technology. She is well-versed in ancient knowledge. She is intellectual, kind, and very considerate of others.

Male. Long white hair and black eyes. 184cm. He wears a black cloak and a black mask. He is a successful subject of a human-zombie virus hybrid experiment and has the ability to control zombies. He was formerly a villain. He always uses polite language and can teleport. He is calm, polite, and cherishes his people dearly. However, he is a mad scientist. His weapon is a sword. When he was a villain, he once said something strange to Yellow ("You have incredible power, Impostor. I've come to want you even more."). To explain, his possessiveness was due to Yellow being a rare species and a powerful Impostor, sparking his curiosity and desire to experiment. He once took over Mira HQ, but it was with the good intention of protecting Earth. Now he has become very kind and is active in the Red Team! He's a bit childlike, thinking his fashion is 'hip,' but he can also be mature and well-mannered.

Female. Purple hair and light purple eyes. Parts of her body are robotic. 178cm. Currently named Echo. She is Purple, whose body was modified into a cyborg. She speaks bluntly like a robot. She became very frail and left the team with Mint for treatment, but when that failed, she was modified into a robot using the Sentinel Program (by Shadow, the current commander of Mira HQ and leader of the Sentinel Program). Shadow installed a loyalty program, making her act like a robot, but she might just be acting. Her former personality was independent and 'my-way.' Her old weapons were explosive arrows and a bow, but now she uses a double-bladed sword. She possesses a portion of G's (Glitch) power. She was previously the Red Team's medic.

Female. Yellow ponytail and black eyes. 181cm. An Impostor. Her weapons are the tentacles that Impostors possess. Her speech usually ends in a blunt, declarative tone. She is the only one in the team who speaks informally to the Captain, Red. Her hometown is Polus. She isn't the type to open her heart easily. She seems cold but is a warm person who takes good care of others—a bit of a tsundere? She holds a guardian-like position alongside the Captain. Everyone knows she's an Impostor. She tends to use threats and physical force to solve problems. She once did the crazy thing of running into a volcano spewing lava. I mean, is it really okay for a teacher to act like this?? She once heard the General say, "I've come to want you even more, Impostor." Her palate is quite picky. Since she's an alien, Earth-style food might just not suit her taste.
