Continuity mistake: When Simon Carver and David are speaking in Carver's office, Carver's hands instantly change positions form being spread out on his desk to clasped as the camera shots switch.
Battle Scars - S1-E7
Continuity mistake: When Echo prepares to calibrate the surgical pod, he has a bandage on his head, even though the members of the Bad Batch don't get their control chips removed until near the end of the episode. (00:14:11)
The Mind of Simon Foster - S3-E23
Continuity mistake: When the pawnbroker closes his metal gate, he's facing the wire mesh. When the shot cuts, he's instantly facing away from it. (00:10:15)
A Single Piece Was Lost - S1-E10
Visible crew/equipment: When the Gruenaks attack the Scientist a puppeteer is visible to the right of one of the Gruenaks, just before it grabs the bird cage and throws it onto the Scientist's head. (00:28:18)
Revealing mistake: Mr Knight shoots Suzie Boreton - after the muzzle flashes and sounds stop the bolt of his MK14 EBR continues to move back and forth as if it's still firing. (00:30:30)
Plot hole: White Base and the interior of Luna II withstand without a scratch the explosion of the thermonuclear reactor from the Magellan from just a few meters, while the blast literally vaporizes the Zaku far away from the entrance and threatens to damage the Musai, hundreds of meters away.
'Unmei no sentaku' mitaina - S1-E6
Plot hole: Akito's attack is point blank, on a ship part of a fleet with Distortion Field activated (basically, they have shields, like the good guys' robots). The explosion he causes is according to Ruri's damage report big enough that it managed to vaporize 80% of the ships they were facing, but his Aestivalis and the other 3 right floating nearby make out of it literally without a scratch. (00:05:10)
Triumvirate of Terror! - S3-E8
Continuity mistake: Right at the beginning, the camera closes in on a baseball field. It shows several people standing and walking out in the field and just two standing up by home plate. The view changes to behind home plate and suddenly there are several superheroes sitting and stretching there, and the rest of the field is empty. Then after a shot of Jimmy Olson in the commentator stand, it shows a high view of the field again and the people have all changed again. (00:00:10)
There Is No Normal Anymore - S1-E2
Continuity mistake: The beautiful blonde visitor takes a picture of herself on Tyler's phone. However, we get a perfect view of her as she concentrates to take the snap (looking very serious and studious, barely showing her teeth), but when we see the picture she is wearing a classic toothy smile right across her face. (00:23:00)
Visible crew/equipment: When Phones is unravelling the secret plans, a hand can be seen pulling him back to help unravel the plans.
Deliberate mistake: Season 2, episode 6 "Identity Crisis": When Bizarro starts decaying into the parody form of Superman, his costume goes with it; the blue fades, and even the 'S' insignia changes. Strange that superhero garments change right alongside their wearers when they suffer from an unstable genetic effect. Were the clothes cloned right onto his body, instead of sewn?
Other mistake: When we first see the Saito Gemu HQ, the shot is mirrored. It is apparent by the reversed company logo sign. (00:14:25)
Factual error: Henry states that the car bumper of an 2007 'XJ' is a certain height off the ground and led to a particular injury to a dead person. He claims he knows this because he is a Jaguar enthusiast. He then points to a photograph of the 'New York Kids' in a pre-2002 Jaguar XKR as 'circumstantial evidence' that it was this car that caused the injury. A Jaguar enthusiast would never mistake an XKR for an XJ.
The Two Deaths of Jamie B. - S2-E4
Revealing mistake: When Naomi shows Kirsten the money, you can tell it's fake. Not only are the serial numbers all the same, you can read "this note is not real it is to be used for motion pictures."
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).
Here There Be Dragons - S2-E11
Visible crew/equipment: When Prax leads the group to where Dr. Strickland took Mei, just as they reach the door the two green and yellow T-marks are visible on the floor. (00:02:30)
Audio problem: While Pickles is sniffing the ground, she asks Bob "Did you know vomit tastes bad?", but her lips don't match what she is saying.
Continuity mistake: When Miles jumps off the ferry to swim ashore, the camera view is from the ferry: he jumps into quiet, fairly level water, yet the camera recedes from him (he jumped off the back of the boat as the camera continues moving with the boat). The angle changes and we see the wake of the boat - but it's not what he jumped into.
Continuity mistake: When Molly is in space, alone, a man she knew is on The Other Side of a door that has a circular window in it. The man uses his finger to draw the words "HELP ME." When we first see the words, they are legible and about a third of the way below the top of the window, but the next time the words are much higher up and hard to read, and the third time they are now back to the original place.
Other mistake: The URL seen on Siobhan's laptop (https://internet-search.comm7986/index.html) is obviously a fake URL.
