Deliberate mistake: When the T-Ship is hit from the blast from the exploding space station, it spins around for a while before it re-stabilizes. Just before it does so, look out of Raven's canopy: the background outside with the stars and even a planet spin as the ship does, whereas realistically it should remain calm and stable.
Continuity mistake: In the beginning of the episode, Cyborg is sleeping and the console beside him begins beeping and says "sleep cycle complete". Each beep, a red line on the screen wiggles jaggedly like a heart monitor. But it cuts to a close up during one of these beeps and suddenly the line is not moving half way through the beep, then starts up again after a short delay. (00:00:15)
Continuity mistake: When Starfire asks what is the Maximum 7, her, Robin, Raven, and Beast Boy are standing together looking at Cyborg in a wide shot. Raven is slightly behind Beast Boy but to his right, and her body is facing to her left. But then it cuts to a close shot from in front of the Titans and suddenly Raven is on Beast Boy's left and right beside him, with her body facing her right. (00:03:50)
Continuity mistake: The Titans race to confront Billy Numerous for the first time. When the T-Car skids to a stop in front of Numerous, he just looks at it, startled. But in the very next shot (the close-up of his head) Billy is suddenly jump-cutting to shield his eyes with his right arm. (00:09:25)
Continuity mistake: Once Billy Numerous splits into 10 copies, you see the Titans standing outside the T-Car. The boys are on the ground and the girls, Raven and Star, are hovering above them. It then cuts to a camera move going around the car and suddenly Raven and Star are hovering above the car itself. (00:09:45)
Continuity mistake: When trying to redistribute his power to continue chasing down Billy, Cyborg looks at a bar graph read out on his arm of what is using how much power. The bars are constantly fluctuating back and forth on the close up. But in the angle showing all of Cyborg's torso, his arm is visible with the graph on it, and the bars are not moving. (00:12:40)
Continuity mistake: After Cyborg is hit by the truck, he stands up and sees three Billy copies in the back of it. The one on the right has his arm behind the leg of the one in the middle. It then cuts to a close up and suddenly the one on the right has that same arm out waving at Cyborg. Also the box on the top left has dirt appear in the left corner below the lid. (00:13:25)
Continuity mistake: Cyborg reawakens after being overloaded by the Max 7 and opens his eyes. Robin is standing directly in front of him. But then it cuts to a different angle and suddenly Robin is off to Cyborg's side and he has to turn his head right to look at Robin. (00:17:05)
Continuity mistake: When Starfire is force-fed pie by Mother May-Eye, she swallows a rough clump of pie before pretending to be mind-controlled. But after may-Eye leaves, her tongue evicts a whole pie from her mouth, plate and all.
Suggested correction: It's not hard to believe that Starfire's tongue has the ability to retrieve things from her stomach. As she is an alien who has multiple stomachs and many strange qualities.
Continuity mistake: Starfire manages to keep away the pies Mother Mae-Eye is force-feeding her, even to the point that her lips are kept clean. But when Mae-Eye sends in the Turbo Love 3000 XL mega pie, Starfire's mouth is suddenly stained with pie filling.
Continuity mistake: When Mother Mae-Eye beds the Titans down in the pie plate, we can see the cushions being close together, forming a closed line. But when Mae-Eye says good night to each Titan in turn, the cushions behind each Titan are isolated from one another.
Continuity mistake: After Mae-Eye is banished back into the pie, the Titans assemble around it to ponder its fate. In the shots where we can only see their feet, they are positioned (clockwise, starting at 1 o'clock): Beast Boy, Starfire, Robin, Cyborg, Raven (who takes Silkie's place). But when we see their faces from the ground up, their positions are (taking the new perspective into account): Beast Boy, Robin, Starfire, Cyborg, Raven - on the whole meaning that Robin and Starfire switch places from one cut to the other, and back again.
Plot hole: After the Titans have recovered their senses, they engage Mae-Eye and her gingerbread men. Just before Cyborg and Raven are trapped in giant jars, they blast Mother Mae-Eye directly from behind. But for her to enchant them, she just turns to her left and casts her spell to her side instead of behind her.
Continuity mistake: Hot Spot and Wildebeest get captured by the Brotherhood of Evil and flash-frozen as battle trophies. In each instance where they are seen afterward, the two are seen standing in different stances.
Factual error: 5-2 "Homecoming Part 2": The key Madame Rouge forms with her finger to open the handcuffs in the introductionary flashback scene is a key for a cylinder lock. But the handcuffs' keyhole is styled to accept a bit key.
Other mistake: When Red Star introduces himself, he takes off his parka with both hands. But as it drops to the ground, you can see the fingertips of his hands on top of the screen, standing completely still. This setup looks unnatural, as if he had suddenly taken off the parka with some telekinetic power.
Plot hole: When the raptors bring down Beast Boy in his Tyrannosaurus form, he escapes the batch lying atop of him by turning into a dragonfly. When he does so, the heap of dinosaur bodies does not sag down at all, and to fill out the gaps, a whole lot of additional raptors appear in his stead from God-knows-where.
Continuity mistake: When Gnarrk attacks Dr. Light's amplification machine, the wrench Cyborg threw at him has suddenly grown in length. At first his fist encloses the whole grip, but a minute later it is long enough to be used as a club.
