Continuity mistake: Takumi and Shingo both have their right hands duct taped to the steering wheel, as per the rules of the Gum Tape Deathmatch. During one shot of the race, Tak's hand is no longer taped and resting casually on top of the steering wheel as opposed to the right side of it.
Revealing mistake: We can see Ecliptor's zipper from behind - slightly revealing on Saban's part, considering Ecliptor is supposed to be an evil monster henchman of Astromena's.
Continuity mistake: When Kung Lao and Shang Tsung are preparing to fight each other at the tournament, watch Shao Kahn. He gets up off his throne, then it cuts to wide shot and he's sitting down again. Then it shows him standing up again only to go back to sitting down a fraction of a second later. (00:03:40)
The Powerpuff Girls Best Rainy Day Adventure Ever / Just Desserts - S2-E10
Plot hole: The children decided that they hated the Powerpuff girls in one day. Then how did they have supervillain costumes and a van? The mom said they had lots of time to prepare.
Crystal Blue Persuasion - S3-E15
Factual error: When Frank, Olga and he rest of the Back Step Team meet Commander (a Navy O-5 Rank) William Streck, he is dressed in a U.S. Air Force Uniform with the rank of Colonel (O-6).
Winning Through Intimidation - S1-E15
Continuity mistake: Panik's Metal Guardian can be seen on the field several minutes before he actually plays it. (00:10:30 - 00:13:00)
Plot hole: During the episode "Superstition", Onizuka thinks he has cancer because the magnetic pain-pads he was wearing created strange blobs in the X-Ray he has taken. However, given the fact that the X-Ray was so strange, doctors would have given him a complete physical, and noticed the pads much sooner. Here, they literally just assume he has tumors, and fail to ever take notice of the pads. Simply impossible, given the gravity of the situation. (Obviously, this is to pay off at the very end of the episode.)
Sammo Blammo - S2-E1
Continuity mistake: In the scene at the bank, he has a bomb attached to him and an ex-bad guy handcuffed next to him, the handcuff is roughly a foot long, making the distance short between him and the guy next to him. Sammo fights a gang of thugs in the bank and does a swing round kick and his handcuff is detached or widens by 3-4 ft. The guy on the floor is rolling around to make it look like he is attached to Sammo, but is clearly not.
The Planet of Dr. Moreau - S1-E4
Continuity mistake: When the Silver Surfer first discovers he has been enslaved, his board is buried in the ground. When he breaks free of the enslavement and calls his board back to him, it is wedged in the side of a mountain.
Character mistake: When the gang is watering the horses, Chris walks over to meet Mary's man friend (whom she introduces as an old friend of the family) and the mystery man tells Chris that he'd proposed to Mary long before 'Frank' when Mary's late husband was Steve.
