Never feed Gordon chocolate - otherwise, he'll turn into this thing
Considering the show is based on the Grimdark comic Gear, the show has some astonishingly creepy moments.- Waffle goes through a disturbing Nightmare Sequence when he's temporarily convinced that he's evil. He goes completely insane and tries to initially murder Gordon and Mr. Blik in a death trap.
- "Bringing' Down the Mouse" has Waffle trying to catch a mouse to be a part of a mouse-catching brotherhood like Blik and Gordon. He ends up facing a dreaded mouse named Squeakus, who even his brothers are afraid of. The mouse in question is a creepy Killer Rabbit type with a constant drooling Slasher Smile and considerable bloodlust.
- In "Core-uption", Gordon feels sorry for Human Kimberly when she gets an "F" on her science project, a diorama which says that the Earth's core is made from unicorns and rainbows. He decides to make the core just as she thinks it is by drilling to the center of the Earth and sticking the diorama into it, which turns the world into a Sugar Bowl. This has the disturbing effect of turning Mr. Blik into a doll, who painfully loses his body parts, and Waffle into a talking flower. The cuteness eventually becomes too much and threatens to destroy the planet.
- The Body Horror from Gordon's allergy to Broccoli. Even worse when his brothers try to kill him when they think he's a monster.
- As the page image shows, Gordon's later revealed allergy to chocolate turns him into a pulsating mass of pure Body Horror.
- The Bear, a recurring realistic grizzly bear, which aggressively mauls and eats the Cat brothers more than once. It's not played for laughs and is horrifyingly bloodthirsty.
- Waffle inadvertently causes a Zombie Apocalypse by grabbing the wrong book on a bookcase to cook a meal. The zombies invade the Cats' house, eat their food, and then try to eat them. The brothers and Hovis are nearly overwhelmed and eaten if not for Waffle saving the day with lasers.
- Mr. Blik dies on two occasions (first getting eaten by sharks and second getting eaten by a giant meteor worm) and it's shown in full detail.
- Blik temporarily gets magnetic powers from static buildup in his fur. As the episode progresses, it slowly grows more powerful and more uncontrollable, to the point that it was dragging large freight ships and multiple blades towards Blik. He's nearly killed before his powers suddenly wear off.
- Though played for laughs, Gordon's obsession with Kimberly is blatant Pædo Hunt, considering she's a nine year old girl and he's the equivalent of an adult for his species.
- In "Duck and Cover", Gordon was extremely terrified of a duckling because of an incident that happened when he was a kitten (the duckling beat the snot out of him with tremendous superhuman strength and horrific fighting skills, and for no apparent reason at all). At one point, the duckling turns feral, beats Gordon brutally, and then viciously attacks Waffle and Mr. Blik.
