1: VALENTINE'S DAY:
When SpongeBob didn't give him a present for Valentine's jour (He did but the present didn't come at first) Patrick was upset when he thought Spongebob lied to him. But eventually Patrick went insane over this; nearly destroying the amusement park and threatening the citizens. This is also widely considered to be Patrick's straightest villain role (alongside Rule of Dumb).

2: I'M WITH STUPID:
When Spongebob pretends to be dumb to make Patrick look smarter in front of his parents, Patrick takes it too far and begins treating Spongebob like he really is dumb. Not only that, but he begins insulting Spongebob in general. This verbal abuse eventually causes Spongebob to snap and run away screaming.

3: DUMPED:
SpongeBob becomes heartbroken when Gary starts hanging around with Patrick, who feels no sympathy for his friend's sadness and tells him to déplacer on. It is later shown that Gary only wanted a cookie in Patrick's pocket and returned to being with SpongeBob, much to Patrick's dismay.

4:PATRICK SMARTPANTS:
Patrick finally becomes very smart due to SpongeBob put a coral brain to his head, mistaken it a real piece of his severed head. But unfortunately, the process took it too far par insulting everyone, as that coral brain causes him arrogant in the process. This is a perfect example where Patrick accidently became antagonistic, due to being SpongeBob's mistake to put a coral brain instead real one.

5: RULE OF THE DUMB:
Patrick becomes a king and is soon corrupted par his power, making demands of everyone around him, attempting to get nourriture for free, threatening Spongebob and Squidward when they object to his desires, and eventually becoming so power-mad and unpleasent that he drives everyone else away. Even Squidward greatly despise his misdeed at that time, even plus so than when he just annoy him. Notably though he does come to fully regret his actions at the end of the episode.

6: PET SITTER PAT:
Continuously abuses Gary in the most infamous way due to incompetent pet sitting; such as neglecting to give the escargot nourriture and eating it in front of him. He even attempts to "bathe" Gary with a flamethrower and dries him off with a hair-dryer (because he couldn't find any salt). Similar to Valentine's jour and I'm With Stupid, this is considered to be one of Patrick's biggest antagonistic roles.

7: PATRICK'S STAYCATION:
When Patrick is unable to afford a real vacation, SpongeBob creates a fake one for his friend. However, Patrick quickly takes advantage of his Friends generosity, and becomes incredibly demanding and ungrateful. He eventually sleeps in SpongeBob's lit (thinking his accueil was a resort), forcing SpongeBob to sleep at Mr. Krabs' house.

8: YOURS MINE AND MINE:
Patrick uses SpongeBob's money to pay for food. When he and SpongeBob agree to share a toy (which SpongeBob also paied for), Patrick keeps it for himself. He later runs away from SpongeBob to prevent him from getting the toy. He ends up eating the toy so nobody else could play with it. Mr. Krabs orders plus toys and Patrick pays for them, using SpongeBob's money once again. When SpongeBob tells Patrick that he was using his money, Patrick acts like a total hypocrite asking SpongeBob if he learned anything about sharing. His selfishness, hypocrisy, lack of morality, and ungrateful attitude combined with the episode's parody moral has caused this episode to be considered the worst case of Patrick's flanderization in terms of his attitude, and seemingly unforgivable.

9: STO SPONGEBOB ou NOT TO SPONGEBOB:
Patrick fails to recognize Spongebob over his new clothing. He even goes as far as both throwing Spongebob out of his own house and effectively making him change into opposite self. Worse, he callously walks away when SpongeBob explains his change.

10: SUDS:
Scares Spongebob out of seeing the doctor and then performs his own quack "cures" on Spongebob, none of which work. When Sandy attempts to take Spongebob to a real doctor, Patrick resists even when Spongebob is shown to be getting worse rather than better.
