Plot hole: Officer Jenny asks Ash what he knows about the "trio" when he tells her that the pirates are likely Team Rocket, but he hadn't said anything about there being three of them before that. And Jenny obviously didn't know anything about Team Rocket, either. (00:05:30)
The Mandarin Island Miss-match - S2-E18
Character mistake: Prima tells Jynx to use Ice Beam, but she very obviously uses Ice Punch. [This is actually a result of mistranslation. In the Japanese version she orders Jynx to use Ice Punch.]. (00:18:50)
Plot hole: When Team Rocket decides that they're going to capture Dragonite after it's been worn out, they appear in the blimp above the battlefield no less than ten seconds after they were shown in the stands. There is just way too little time for them to have possibly gotten up there that fast, even allowing for anime physics. (00:14:30)
Character mistake: Misty is notoriously afraid of bugs. She makes this clear whenever bugs are around. She seems to be OK with Tracey's Venonat, but for some reason doesn't think it should be classified as a bug, when its type is Bug/Poison, and it's quite obvious that "Venonat" comes from "venom gnat, " a gnat being an insect. She even directly states that "At least they're [Venonat and Marill] not Bug types." [This error doesn't happen in the Japanese version.]. (00:03:19)
Other mistake: When Team Rocket is running away with the trophy, James falls flat on the ground, and an indentation of his body as well as the trophy is made. The indentation shows a perfect match to the trophy, but James' arms were partially covering it, so there shouldn't be a perfect indent of the trophy in the ground. (00:05:18)
Continuity mistake: When Misty says, "I wouldn't be surprised if the next gym leaders are tougher than the last ones," the right strap of Tracey's rucksack is on his collar, but in the next shot, it is not. Also, the marks on Ash's cheek go from looking like zs to looking like two pairs of lines. Additionally, his mouth is open, but in the next shot, it is closed. (00:01:42)
Continuity mistake: When Professor Oak asks, "Are you there already?" there are lights and moulding on the screen, but in the next shot, there are not. (00:06:31)
Continuity mistake: When first showing the entrance to the satellite dish, three blocks are above the doors, but in the next shot, there are two. Also, there is a sign that says, "Keep Out," but in the next shot, there is no text on it. Additionally, there is a sign with "WARNING" with a skeleton angled to the top right coner of it with its arms and legs straight, but in the next shot, it has "WARNING!" with its skeleton pointing to the top left corner with its limbs bent. (00:06:42)
Continuity mistake: When Tracey says, "There'll be guards everywhere now," Misty is behind Ash, but in the next shot, she is not. (00:10:31)
Revealing mistake: As Ash, Misty, and Tracey are making their way through the crowd, Tracey clips through one of the people in it. (00:05:33)
Continuity mistake: When Professor Oak introduces the Johto Pokédex to Ash, its black antenna turns red. (00:14:42)
Continuity mistake: When Tracey recalls Scyther, the ring around the button on the Poké Ball disappears. (00:20:36)
Continuity mistake: When Lickitung runs into Victreebel, its pink eyebrows turn yellow. (00:17:15)
Continuity mistake: When Ash throws a Poké Ball to catch Scyther, his bag disappears. (00:04:40)
Continuity mistake: When Tracey asks if Misty is coming with him and Ash, part of Misty's arms changes from skin-colour to yellow. (00:01:49)
Revealing mistake: When Ash's friends run over to him, as he dives into the pool, Pikachu can be running in midair. (00:14:27)
Continuity mistake: When Team Rocket blasts off, Arbok's pattern changes from red with yellow centres to yellow with red centres. (00:19:03)
Factual error: It is stated in this episode that Ghost types are strong against Psychic Pokémon. However, in Generation I, Psychic types were only weak to Bug-type attacks. It is also implied that Ghost-type Pokémon are immune to Psychic-type attacks. However, they actually take normal damage from Psychic-type attacks.
Continuity mistake: When Ash calls out to Pikachu after he disappears, his bag disappears. (00:03:49)
Revealing mistake: When Ash tells Lapras to go back to the ocean, his left arm is transparent. (00:14:18)
