King Cobra - S3-E6
Continuity mistake: When Miguel realises Johnny liked all Ali's photos, he looks embarrassed and shakes his head to the right, with his mouth open. In the next frame he looks significantly different, with his mouth shut. (00:09:23)
Revealing mistake: When Silver cuts open the box of new equipment, the razor knife has no blade. (00:05:53)
Other mistake: Johnny is browsing Facebook and accepts a friend request for his childhood crush and checks out her profile. The Facebook post on Ali Mille Schwarber's profile with a photo of her smiling has a lock icon next to the date. This indicates that the photo/post is private and no-one should be able to see it except for Ali. (00:36:58)
Other mistake: When Miguel and his friends use the restroom, he zips up after using the urinal, but there is no zipper on his costume when he turns around.

Continuity mistake: Tory's hair looks disheveled at the start of the house brawl. When she shouts "No Mercy!", her hair looks better. The intro must have been filmed after the brawl.
The Good, The Bad, and the Badass - S3-E8
Continuity mistake: In the beginning of the episode when Daniel and Johnny try to pick up Robby from juvie, the background shows that the weather changes in an instant. When they're arguing, it's raining. When Robby refuses their help, it's sunny.
Audio problem: The man Larusso neglects to sell his dealership to thinks he just got the deal before being punked. He turns around to talk to his assistant but the audio here is off enough to be noticeable. His mouth doesn't match briefly.

Continuity mistake: When Daniel threw his Crane Kick in the '84 movie, Johnny fell back and crawled away holding his nose as Daniel jumped around on one leg. But in the opening scene of this episode, Johnny is now prone on the mat as "Daniel" stands there in fighting position.
Character mistake: Considering she was wearing heeled boots, Ms. Underwood should have either taken her shoes off or at least have had a carpet provided to her if she was going to sing on the competition mat, as her shoes could have torn it. Other than emergency medical professionals, anyone who is going to step on the mat should remove their footwear.
Strike First - S1-E2
Continuity mistake: During the pool party where Sam is hanging out with Yasmine and Moon, Yasmine holds her cup high in one shot but then low in the next.
Answer: Just like in the original film, some guys want that brutality. Johnny in part opens the dojo because of his past rivalry with Daniel and to train a kid that's being bullied. But also, other kids that are being bullied want to join in order to learn to fight back. Johnny is also teaching the Cobra Kai creed (Strike First. Strike hard. No Mercy.") so that's why he opens his dojo with that name and the old Cobra Kai dojo's past reputation is exactly what he wants to elicit.
