An alien who is relatively kind-hearted and naive by nature, but from the Space Police's perspective, he's a legendary screw-up, a liability, and a troll whose very acceptance into the force is a mystery. For comedic effect, his personality is nerfed to the point where he mistakes reality for a game, destroys perfectly fine planets, and shifts the blame to his superiors. To the audience, he's a shameless and selfish troll on par with the Beast Friends. The bigger problem is that he doesn't seem to realize how incompetent he is; instead of improving, he becomes more of a liability as episodes progress. He's also a bit of a simp. A comedy character.

A veteran with decades of experience and the superior officer to Kim Deok-bae and Kim Mal-sook. He's a perennial Deputy Chief aiming for a promotion, but he keeps failing to move up due to Deok-bae's countless blunders. Unlike Deok-bae, who makes many mistakes and gets caught up in emotions, he is a realistic officer who restrains his feelings and makes cold decisions befitting the Space Police. He tends to swear frequently. A comedy character.

As the middle-ranked member of the trio, she suffers the most. She has to endure Park Dong-pal's nagging while cleaning up the messes made by her incompetent subordinate, Kim Deok-bae. However, as a member of the Space Police, her combat prowess is significant enough for Deok-bae to openly describe her as 'insanely strong.' A comedy character.

Forcibly renamed Kim Chun-sik due to a slave contract with the Space Police; he introduces himself as Kim Chun-sik in subsequent videos. He is the former President of Planet Bitoretel. He was unfairly tortured after Deok-bae kidnapped him by mistake instead of the intended target, the Minister of Gender Equality. In the meantime, Planet Bitoretel was destroyed by a meteor strike, making him the sole survivor. Though a slave, he serves as a helper. A comedy character.

An alien lifeform that resembles a puppy. It cannot speak and only says "Hambug." It has ears like sesame buns, a body like a sausage, and a red ball-like object on its tail.
