Max Green's relatively normal life changes after he discovers that his newly adopted siblings, Teresa and Goliath, are aliens posing as children. Since his parents will not believe him, Max is left to foil the aliens' earth-dominating plots. Max receives help from his friends, including Violet – Max's friendly nemesis since kindergarten, Pixel – the town's nerd and most convinced alien believer, and Simon Sillicon – a genius scientist fallen into disgrace.
Characters
Max Green is an energetic, outgoing 11-year-old. He is good at sports, talented in music and academics, and was popular at school until Tersa and Goliath, his adoptive "siblings" showed up and stole the show. His goal is to try and expose his alien siblings for attempting to use his home as a home base for stealing Earth, and to stop their daily reports about the human race to their home planet, Kemii.
Loom Prxbtlyp, also referred to as her civilian name, Teresa Green is, upon first inspecton, a polite, neatly-dressed, well-behaved pre-teen girl who was adopted by the Greens family. She's a straight-A student and respects her elders. But in actuality she is an alien creature dedicated to taking over the earth and enslaving its inhabitants, as her job is to send nightly reports describing the human race to the orbiting Kemii to speed up the impending invasion. She has trouble grasping the subtleties of human nature, and tends to see humans as illogical and like an ant farm. Loom chose her disguise of a cute 12-year-old Teresa based on characters she saw on a movie billboard from across the Greens' house, and named his brother Goliath off of a dog's ID tag.
Ran Strb, also referred to as his civilian name, Goliath Green is a 380-year-old alien who was nearing retirement when he got his assignment and thought the job would be a drag. Goliath doesn't speak in any Earth languages, and instead speaks an unintelligible Kemii language. His body is heavily clothed and he has a mop of pumpkin-orange hair, so only a portion of his face is ever shown. He also has a long vegetal tail with a mind of its own, and can extend a slimy psedupodal green stalk-body on which he can elevate his kindergarten-sized self to an intimidating 20-feet high.
Victor Green is a loving, if somewhat distracted, father and a doting husband. He has the ambition of doing great things for his family. He and his son, Max share a positive outlook on life, and a slight tendency to be unrealistically optimistic. He is a mid-level executive at Cucurtown's biggest business, Cutlery Land.
Laura Green is Max's mother, and she loves her children. She also loves gardening. Her primo gourd-growth is the reason her backyard was chosen by Loom as the landing site for the Kemii Advance Team, and her prize-winning pumpkin is alien headquarters. Laura is a happy homemaker with a college degree in Botany, but beyond her garden and family she has a big ambition; to compete someday on the popular weekly TV game showWho Knows What with her large, and growing expertise in koalas and Australian Rules Football.
Pixel Sillicon
Chubby 11‐year‐old Pixel Sillicon loves aliens. His father is a dedicated UFOlogist, which accounts for Pixel's interest, but not for the depth of his ardor. Pixel believes he was abducted by aliens and he sincerely hopes to be abducted again one day – so he leaves his bedroom window open at night and has an arrow of lights on the roof pointing to his room. Pixel's easy credulity makes him a less-than-perfect ally for Max's campaign to convince the townspeople. He's loyal to his good friend Max, not least because Max actually lives with two aliens. Despite his admiration of Max and acknowledgment of Max as the anti-invasion Team Leader, Pixel is romantically attracted to Teresa, and believes he and she could rule earth between them as benevolent King and Queen. Dylan Jones provides his voice.
Simon Sillicon
Pixel's father, Simon Sillicon, abandoned his foundational computer work to devote his genius to discovering the aliens he has been convinced have been walking among us for 30 years. The real scientific community shunned Simon years ago, so for three decades Simon has worked, inventing hitech gleaming gadgets and computer programs to fight the alien onslaught he's certain is coming. Simon is so tech-focused, so intent upon his devices and computer algorithms, the issue of being bossed‐around by two kids doesn’t come up. He's glad to be of service in any plan that Max or Violet contrive. He is voiced by Matt Ban.
Violet Violet
Violet Violet is a smart, strong-willed, trend-bucking 11-year-old girl with a BIG fashion sense and a blog describing how she’d like to improve the world – its music, aesthetics, and especially its rigid, closed-minded people; like the teachers who won’t let her wear a swan hat to class. She wears violet clothing, dyes her hair violet, and is looking for a violet pet. To her, the color represents the repudiation of conformity. Her being strong-willed is a problem, because Max is strong-willed too. These two, competitors in school and now in saving the planet, seldom see eye-to-eye. Each one wants to run their alien-busting outfit and each chafes at anything sounding like "orders" coming from the other. She is voiced by Stephanie Pam Roberts.
