Frankie (real name Francesca) works as a merchandise factory laborer at Park Planet and also helps out Sparky at his scavenging business. She is incredibly strong, able to lift and throw heavy objects with ease, and also known to have "child-like flexibility." She is friendly and seems to have an affinity for animals. She has a rough past, and previously had a history of getting into fights.Nowadays, she seems to be the one keeping Andi from picking fights. Frankie is a stocky, muscular and fair-skinned woman who is shorter than her friend Andi. She has an oval-shaped head and a short, skinny nose beneath a pair of bright lime-colored eyes and thick black eyebrows. Her backwards purple cap covers a mass of tailbone-length, spiky pale brown hair. On each of her ears, she wears two different earrings; her right ear having a blue moon, and her left earring is a magenta heart. Besides her white and purple cap, Frankie wears a white turtleneck sweater underneath a pair of tan and orange overalls in addition to black, steel-toed worker boots. Said overalls have pockets on its legs and are missing its left shoulder strap. Some concept art depicts her wearing a short-sleeve white t-shirt with blue sleeves and triangular rips on the bottom. Frankie is described as a rough, reckless dreamer with a big heart. She is more cheerful, lively, and easy-going than her friend, yet she’s always on her guard. In the pilot episode, she shows that she is prepared to lend Andy a helping hand, even if it means resorting to theft. She also has a knack for engineering, often creating and/or repairing useful gadgets in the home she shares with Andi. Although at times her temperament leads her to crack awkward jokes or behave strangely, which even baffles Andy.

Andi is a young Filipina woman of average height and slim build. She has deep tan skin, and three large freckles on her face; one on her left cheek and two on her right cheek. She has black hair with a streak of grey, tied back into a low ponytail with an orange hair tie, she also has reddish-brown eyes. As an engineer for Park Planet, Andi wears a mixed light-dark green colored uniform, that consists of a turtleneck crop top with puff sleeves, a matching high-waist pencil skirt, long white gloves, and grey tights. For footwear she has long, knee-high black flat boots with orange soles and knee pads. Andi is depicted often as exhausted from her work, described as "running on coffee, overthinking, and spite" and often shown to have a shorter temper then her best friend, Frankie.[3] Andi is quick-tempered and lives in a constant state of tension, worn down by years of responsibility and the strain of her work. The treatment she receives from others only deepens her frustration, leaving her guarded and often cynical. She is tired of the responsibility and stress at work, as well as the way others treat her with disdain, even though she held the position of junior engineer for Park Planet. This disappointment makes her wary and often cynical towards the world around her, which is why she’s not averse to spicing up her speech with the odd strong word. Working as a junior engineer at Park Planet, Andy’s cynical view of the world has only become more entrenched. Even after losing that job, she braces herself for disappointment and hardship – something which will dog her every step. Her guarded nature shows in her body language. Even in moments of success or pride, she keeps herself closed off, her emotions surfacing only in subtle details, such as in her eyes, rather than open expression. However, she truly lets her guard down when she has something to stand up for. Her anger turns into a frenzy that even her friend finds difficult to contain. She reserves her physical strength for moments when she feels the need not only to speak her mind but also to take a firm stand. She saves physical intensity for moments of true conviction, when she feels compelled to act or speak. (Real name is Andrea)

Krash (real name Isaiah. Also goes by Dr.Krash) is a young man with dark skin, freckled cheeks and cyan eyes. His hair is styled into red locs with black roots that are held in a bun, and he has a tattoo on his right chest. Krash wears a black-and-gray coat with a white collar, and a layered blue shirt with a planet symbol underneath. He carries a stethoscope in his coat's pocket. He wears gray pants and blue foam clogs with Park Planet charms. Krash's nails are painted black, and he wears asymmetrical geometric glasses. Krash has two piercings in his left ear and a stud piercing on his chin. Krash is an easy-going person who always finds a way out of trouble. He's extremely wary of his personal things, as shown during the moment when Gwen was playing with his tamagochi collection. Krash is capable of keeping calm even when he's tied up and prefers to think rationally, which also gave him an opportunity to test his new medical tech to recover his broken finger. Even when he panics, he prefers to keep it down, as shown when Frankie and Andi brought a dead cop to him, hoping Krash will heal the man somehow. Despite his sarcastic shell, Krash is actually caring for his friends, but will only go to certain lengths to protect them. He acts awkwardly and aloof when talking to Andi, hinting at a complex relationship between them.
