Robotomy/YMMV

Non Sequitur Scene: Blastus arriving to help Thrasher babysit by dressing up as a nanny and riding a motorcycle into Maimy's house before jumping off as the motorcycle crashes out the window. It's never mentioned again after Thrasher asks Blastus what movie did he see that would possess him to do that.
- Also, Blastus's cabaret-style chair dance after he tells Thrasher that he didn't spend four years of jazz and tap to hide in the shadows. While it does illustrate Blastus's character, story-wise, it comes off as something that could easily be a needless cutaway gag on Family Guy.
Complete Monster: The janitor on the "Mutilation Ball" episode when it's revealed that the "balls" the robot kids use for Mutilation Ball are really the babies of a peaceful race of blue balls that were kidnapped from their parents and that robots who "go pro" (read: get sent to the formerly peaceful blue ball planet to fight the angry parents) aren't supposed to defeat them all; they're supposed to "get caught up in a pointless battle with no end."
Crazy Awesome: Everything, but with special mention to the rules of Mutilation Ball.

"There are 73,411 rules, but once you learn them, it's simple. The ball attaches itself to a player and begins consuming his fluids. Your teammates will mercilessly shoot you with lasers. That's why I suggest you burrow under the ground and suffocate the ball. Then again, I'm your coach and your coach is also trying to defeat you. Anyway, if the field feels like it, it will turn to lava and you'll have a jousting tournament. If not, you can choose to pass the ball or let it eat you, but you must do this above ground and before the dragons attack. See, it's all about strategy."

Crosses the Line Twice: To give you an idea, the friendly, affectionate Weenus gets constantly beaten up and destroyed. In addition, someone dies or is horribly injured just about every 5 to 10 seconds, but gets better moments later.
- Special mention goes to the "Sunshine Class", over-emotional robots who are treated like mentally-challenged children, who their teacher tries to kill by launching them all into the sun.
- And the janitor in the Mutilation Ball episode, who kidnapped the babies from a planet of blue balls and used the kidnapped babies as Mutilation Balls on Isanus, which plunged the blue-ball planet into a never-ending war just for fun -- then gets mad at Thrasher and Blastus for killing the other blue balls because that means the end of Mutilation Ball games for good at Harry S. Apocalypse High.
Ensemble Darkhorse / Memetic Badass: Weenus is already getting this treatment, probably due to his Lethal Joke Character premise... and the fact he's a totally adorable Cloudcuckoomood-swinger.
- Steve.
Memetic Mutation: Weenus's "Shadow Puppet Theater".
Tastes Like Diabetes: The song Blastus and Thrasher perform to get out of taking the No Child Left Benign test was so sickeningly sweet, one robot puked oil, another's head exploded, and a third sliced his own head off with an ax to avoid hearing it (everyone else, however, screamed in terror).
- Also, Thrasher's locker, which is filled with bunny drawings and "Thrasher ♥'s Maimy" grafitti.
Too Good to Last: It got canned after 10 episodes (it would have been 12, but the two unaired episodes were incomplete) and was permanently wiped from Cartoon Network's website.
