Oggy's Batman Gambit in "Mission Oggy" (and its season 6 remastering, "Crackdown on the Fridge"). After realizing that no matter what, the roaches will always find a way into his fridge even after placing several high-security traps, Oggy formulates a new plan to get back at the roaches. The next day, while Oggy is fake-sleeping, the roaches see this as another opportunity to raid the fridge. However, when they open the fridge, they all scream in terror when they find out that this time, Oggy has put all of the traps inside the fridge and they are all armed and ready to attack the roaches. Cue Smash Cut back to Oggy, where he then reveals that he hid all of the fridge's food under his pillow. He then happily grabs a box of chocolatesnote The same one from "Bitter Chocolate" in which the roaches steal all of its contents from Oggy and get away with it. and prepares to eat one. Made even more cathartic when this is the first time that Oggy has ever outsmarted the roaches thus far in the series.
The ending of "Oggy vs Super Roach". As now-super-powered Joey and Marky are taking their well-deserved revenge on their pal-turned-bully Dee Dee inside, Oggy calmly walks near his house. Then he lifts it up, spins it around and abruptly stops. Cue inertia doing the rest as the cockroach trio is launched into the window which breaks off and sails into space, followed by Oggy dropping the building into place and posing proudly. Cue Iris Out.
The ending of "A Bird Of Ill Omen". Oggy spent the entire episode being shot at by a visually impaired hunter who mistakes him for a turkey he is after, not helped by the cockroaches gleefully pranking him into getting blasted. When Oggy's revenge scheme against the hunter backfires and gets him pumped with lead by a dozen of other hunters with poor eyesight, the turkey from earlier, who caused the whole mess, shows up to laugh at him for his misfortunes. Big mistake: Oggy grabs the hunter's shotgun and points it at him with a deadly focused expression. Cue the Feathered Fiend fleeing in terror as the angry cat chases and shoots at him repeatedly, going on a destructive rampage to the city all the way.
During "Race to the Finish", the cats nearly get the cockroaches to leave just by unknowingly pestering them by their remote cars. Too bad one last car zooming past during their departure makes them realize who's responsible.
The end of "Virtual Voyage": Joey returns to his home, only to find his fellow roaches messing with his stuff and not really caring about his disappearance into a virtual dimension. Cue him advancing onto the startled duo rolling up his left sleeve.
In "The Abominable Snow Moth", Oggy defeats the titular now humongous glutton by making it step onto a crowbar, causing it to fly into the air, land on its head and knock the moth out. Oggy then ties it up while it's unconscious.
The ending of "The Neighbor's Cat" reminds us for as much of a childish sweetheart Oggy is, he isnota pushover; after being forced by his neighbor to act and look like a dog amidst the ridicule of his peers, he starts off by giving the titular Jerkass cat A Taste Of His Own Medicine with a solid whack from the exact same mallet the former used to knock Oggy out and make him take place before forcibly returning him to his owner. When the cockroaches, who spent the whole episode making fun of him (and at one point sabotaged Oggy's attempt to escape his neighbor's clutches), show up at the wrong time and place and continue the mockery, Oggy slams his mallet down on them with nothing more but a look that defines Tranquil Fury... before roping them into a sadistic game of imitating the animal noise he's making with more flattening should they fail as punishment. Then he ups the speed at which he's imitating the animals to further torture them. It looks like putting up with the roaches' shenangians taught Oggy a few tricks.
Jack gets one in the episode "All Out of Shape", in which the roaches torture Oggy by making a clay Voodoo Doll of him. Oggy slowly gets more and more mangled as the trio keeps messing with the doll and by the time they've made a roll of toilet paper out of it, Oggy finally loses hope on ever fixing his body and starts crying. Jack saves the day by using Voodoo Dolls of the roachesnote Which Oggy created in a failed attempt to pay the roaches back for their torture beforehand and starts mercilessly inflating them, even after Joey tries to get out of it by morphing Oggy back to normal, until they pop.
In "Copy Cat", Oggy manages to beat up and kick his Killer Robot copy all the way to the moon after destroying his figurines... then does the same to Bob and the cockroaches. Considering all the times they wronged, harassed or attacked him throughout the show, it's really nice to see Oggy actually fight back against them- especially Bob after all of the times the latter beats him up. The final shot is all of them chasing each other, stranded on the moon.
Oggy's Roaring Rampage of Revenge in the season 4 episode "Panic Room". He had the roaches beaten at their own game and deployed a variety of traps via the titular panic room. And even when they turn the tables on him and destroy the house, Oggy doesn't give up and manages to reclaim victory by crushing the panic room into a small cube... with them inside it!
"Little Tom Oggy" follows with a similar ending to "Virtual Voyage", only this time it's Dee Dee who catches his brothers trying to steal his stuff. Furious, he rolls up his sleeves and marches over to them, growling all the while, to unleash hell on them. And unlike "Virtual Voyage" you actually hear Marky and Joey getting their due.
When the roaches end up getting Oggy, Jack and Bob turned into children by a witch in "Back to the Past! (Featuring Olivia)", said featured character is stuck babysitting and is soon at her wit's end. So she ties up the insects and explains that she and Joey will be going on a trip to locate the witch and convince her to undo the spell while Dee Dee and Marky watch the kids. When they naturally refuse, Olivia, with a look that says, "You misunderstand; I didn't say you have a choice," whips out a spiked swatter and the cockroaches swiftly change their minds! Yes, the character who is Friend to All Living Things actually threatens the trio with bodily harm when she thinks they've gone too far and successfully gets them to do what she wants!
The ending of "Oggy is Getting Married". After a tumultous series of events and a misunderstanding involving an innocent man in Venice, Oggy shows Olivia the wedding ring, and she happily accepts it, finally allowing Oggy to get the girl after three seasons of pratfalls. Doubles as a Heartwarming Moment since it's the biggest bone thrown at him.
