Robotboy (2005-2008) is an animated television series. The eponymous protagonist is the latest creation of the world-renowned scientist Professor Moshimo. Due to fears that Robotboy would be stolen by his arch-rival Dr. Kamikazi and his main henchman, Constantine, to be used to take over the world, Professor Moshimo entrusts Robotboy to 10-year-old Tommy Turnbull, his biggest fan. While being protected by Tommy and his two friends, Lola and Gus, or "G-man" as he calls himself, Robotboy learns how to behave and act as if he were a real boy.
The spider on Robotboy's flashlight in "The Return of Robotgirl" has four eyes instead of eight.
The tapeworm situation in "Tummy Trouble" — geez, where do we start? First, tapeworms are several feet long, not one inch. Secondly, tapeworms eat their food by diffusion and active transport, not with a mouth. Third, the doctor's scan near the beginning of the episode shows the tapeworm in Gus's stomach, not his intestines where it should be. Finally, having a tapeworm in your stomach does not make you super-thin in less than a few days.
Evil Counterpart: Protoboy to Robotboy, Kamikazi to Moshimo, Kurt to Tommy. Especially noticeable in the Robotboy/Protoboy case — Robotboy was turned evil in a couple of episodes by Kamikazi, but it's always reversed by the end, and Protoboy is pretty much what Robotboy would be if Kamikazi turned him evil without Tommy finding a way to switch him back.
Evil Is Petty: In "Bad Nanny!" aside from getting trying to get revenge on Gus and Tommy, Felonious Hexx (in disguise as their nanny) also orders pizzas for a hundred people all the way from Mexico.
In "Kamispazi!" when Constantine disguised as Deb bends over to steal Robotboy from off of Tommy's bed, he's interrupted when Dwight sneaks up on "Deb" and squeezes "her" butt off-screen, complete with honk sound effect.
Gone Horribly Right: Kamikazi attempted to turn Protoboy evil, but went too far and made Protoboy too evil to the point of being nigh-uncontrollable.
Gretzky Has the Ball: In "Bowling for Dummies" when Debs thinks she's scored a strike she yells "Homerun!"
Happy Birthday to You: In "Everybody Loves Grandma" General Yakitori throws a birthday party for himself and has his robots sing The Birthday Song, but as they're malfunctioning they can only repeat the first verse over and over.
Jerk with a Heart of Jerk: In "The Revenge of Protoboy" when Donnie thinks he's killed Gus he first appears to show remorse, but it's soon made clear he's more concerned about getting in trouble than having killed someone.
Karma Houdini: Donnie. This is lampshaded by Tommy in a few episodes.
Kick the Dog: Kurt throwing a ball at some random crippled kid in "Kami-Chameleon".
Ocular Gushers: Robotboy in "Crying Time" after he watches the ending of a sad play, and Robotgirl in "The Return of Robotgirl" after Gus tells her she looks terrible. Did we mention they both cry oil instead of water?
Panty Shot: Several kids in "The Donnienator"; Lola in "Traffic Slam."
Pinocchio Syndrome: Robotboy wanting to become more human is a recurring theme, especially in seasons three and four.
Pintsized Powerhouse: Robotboy and Robotgirl. Averted with Protoboy, since he's a little bigger than both of them.
Psycho Prototype: Protoboy. Even before Kamikazi made him evil, he was still one hell of a nutjob — this is seen in a flashback when Moshimo first activated him and Protoboy's immediate reaction was to beat him up.
Psychic Powers: Robotboy's probability calculator in "The Soothsayer".
A Real Man Is a Killer: Subverted in "Kamispazi!" when Donnie gives his mom a cooked squirrel with his dad saying that he trapped and skinned it by himself...but then reveals it was actually roadkill.
Retcon: In "Brother," Moshimo says that his first encounter with Kamikazi was when he kidnapped Protoboy. Later, in "The Legend of Brainy Yak," Moshimo relates his childhood as a yak herder in the Alps, and notes that a young Kamikazi made fun of one of his yaks.
Rummage Fail: In "Traffic Slam" when Dwight needed a spark plug for the car, Debs ironically found one in the glove compartment while frantically looking for more cookies, but since it wasn't cookies she just threw it out the window and it fell off the bridge and into the water.
Scarecrow Solution: Used very briefly when Gus pretends to be another Moshimo robot in "The Return of Robotgirl" to distract Protoboy, but it only works for a few seconds.
Small Name, Big Ego: Lance Cosgrove, a self-absorbed investigate reporter who keeps making up the most ridiculous tabloid explainations for anything Robotboy is involved in. Both Tommy's and Lola's dads love watching his show because they think he's So Bad He's Good.
Also Gus — an example would be when he tries to show Robotboy how to win a girl over and ends up making Robotgirl cry.
Too Dumb to Live: In "Science Fear" Kurt almost died from heat exhaustion because he got into a mecha without air conditioning and refused to get out because he was having too much fun trying to kill Tommy.
Too Spicy for Yog Sothoth: In "Runaway Robot!" when Robotboy runs away to live with Gus, Kamikazi refuses to go anywhere near Gus' house because Gus' Amish parents creep him out.
Undying Loyalty: Robotboy and Robotgirl to Moshimo, to the point where they (or at least Robotgirl) would willingly sacrifice themselves for him as proven in "The Return of Robotgirl".
Unusually Uninteresting Sight: In the episode "Kami-Chameleon", two of the teachers have weird limbs and different voices (they're actually Kamikazi's cronies in disguise) and Robotboy shows up in gym pretending to be a student.
Villain over for Dinner: Subverted in the final episode, when the Turnbull family and the Kamikazi family end up having Thanksgiving dinner (or something resembling that) together after Tommy's mom drops by the house of Kamikazi's mom. Apparently, the two mothers knew each from before on.
Why Do You Keep Changing Jobs?: Felonious Hexx has a different job every time he appears. First he was s a magician, then a school nurse, then a dentist and then a nanny.
With Friends Like These...: Gus is selfish, self centred, greedy, vane, ego centric, rude and disgusting with no redeeming quallities whatsoever. Yet is Tommy's best friend, despite the boys willingness to take advantage of the young hero whenever possible, and its never explained why that is.
