Also known as the Aliens Ate My Homework series.A children's series about a 12-year old that has a tiny spaceship crash into his room, and ends up helping the aliens on their mission.Written by Bruce Coville in The Nineties, the series in chronological order is: Aliens Ate My Homework, I Left My Sneakers In Dimension X, The Search for Snout (or Aliens Stole My Dad if you live in the UK), and Aliens Stole My Body.
Evil Is Petty: BKR is implied to be Space Hitler and starts the book in his latest scheme — bullying children at an elementary school.
It should be mentioned that according to the aliens, the worst possible crime is cruelty, because unlike other crimes which might have mitigating factors, if you're cruel, it's because you willingly choose to be.
Fantastic Honorifics: The "Tar" of Tar Gibbons is an honorific meaning "Wise and beloved master who could kill me with his little finger if he so wished."
For the Evulz: Everything BKR does is for this, such as his plan to merge our dimension with Dimension X and his later plan to freeze time. Grakker notes in both cases that BKR is well aware that he would be affected just like everyone else, but as long as he can hurt people, he just doesn't care.
"It" Is Dehumanizing: Rod points this out when the Tar asks to be referred to as 'it', but as it points out, it is neither male nor female, making the corresponding pronouns wrong and therefore insulting in their own right.
Sarcastic Confession: By accident. "Aliens ate my homework" was the honest truth, but as Madame Pong pointed out, it was such a bizarre explanation that nobody could be expected to take it seriously.
Screw the Rules, I Have Money!: At one point, Arnie the school bully tries to have his dad sue Rod's mother, because Rod (with a little alien help) ducked his fist and he broke it against the school's wall. While there's no way that it would hold up in court, Rod's mother mentions that she can't afford the trouble.
Of the five alien crew members 2 that are roughly male, 1 female, 1 plant that uses male pronouns, and 1 with no equivalent in Earth's biology that considers male or female pronouns insulting. When Rod's cousin asks why there is only one female, she explains that the sheer diversity of species means they don't even pay attention to that kind of thing anymore.
Tragic Monster: Smorkus Flinders, BKR's friend and partner, was once a kind and decent person until he was caught in a particularly horrific Reality Quake and turned into the monster he is. Unlike BKR, who simply does what he does For the Evulz, Smorkus Flinders does what he does as a way of lashing out at life and the universe for what they did to him.
