Nationality: Republic of Korea Gender: Male Age: 17 Year of Birth: 2035 Height: 172cm / Weight: 68kg Family: Father Kang Cheol, Mother, Cousins Min-jun, Hana, and Duri Exclusive Suit: Phoenix Affiliation: Firerobo Member He has reddish-brown hair. Like his father, he dreams of becoming a firefighter, but he is usually playful, terrible at studying, and sometimes eccentric. However, he gets his work done properly and is a member who excels in practical application over theory; though his training scores are a mess, he plays a huge role in actual missions. The suit he equips is the Phoenix. His life before transforming is quite a series of misfortunes: his pants were pulled down, exposing his underwear on a live broadcast; his crush Yuri's heart was stolen by Tae-o; he was banned from deploying by Dr. Jeong for fighting with Yu-chi and Chan-ran at school; his lunch box was stolen by Yu-chi and Chan-ran; he was laughed at by friends and kicked in the shin by Sena for claiming he was Phoenix; and he accidentally triggered Team Leader Marie's 'old maid' hysteria and was subjected to torture disguised as special training. His relationship with Tae-o is decent, but he frequently bickers with Sena, who has the opposite personality, like frenemies. Because of this, they both get scolded severely by Dr. Jeong, but they are close enough to worry about each other the most.

The amount of chocolate he receives from girls is endless no matter how much he eats. The suit he equips is the Icarus. He looks cold, but he has a bit of a prince complex and a playful streak, often teasing Ian. His relationships with both Ian and Sena are smooth, so he usually watches or mediates whenever they bicker. However, a downside is his tendency to want to give up on a task before even starting if his performance in it improves. He is the only member among the original Firerobo crew who has siblings.

She is smart, intellectual, and the most intelligent among the three original Firerobo members. In Season 1, Episode 4 'Sena's Past', she fainted during training; in this episode, Team Leader Marie reveals that Sena's parents died while trying to save her when she was trapped in a closet during a fire, and that Dr. Jung invested his entire fortune to create Firerobo because of this incident. In other words, she is the only orphan among the three members. Ian, knowing this, thought Sena collapsed because she was training so hard due to trauma and tried his best to help her, but it turns out she didn't collapse because of trauma, but simply because she was in poor condition due to a cold. The suit she uses is the pilotable Hercules. She has almost no friction with Tae-o, but she has a classic frenemy relationship with Ian.
