- Krabby: Some Krabby cards from the Fossil set have an incomplete Fossil set symbol, where the palm of the bony hand is missing a part.
- Seaking: Card reads "Put Seaking on the Stage 1 card" when it should say "Put Seaking on the Basic Pokémon"

- Misty's Seel (1st and Normal Edition): All prints of this card have a transparency error; there should not be a white space around Seel's tail.

- Horsea (1st and Normal Edition): One of the attack cost energy symbols for its attack is oddly off.
- Natu: Energy symbols for attack are moved to left margin

- Umbreon (1st and Normal Edition): The Psychic symbol in Umbreon's resistance is bigger than normal.
- Kakuna (1st and Normal Edition): The copyright text of all other Neo Discovery cards is "©1995-2001", but for an unknown reason, this card's copyright is "©1995-2000".
- Unown O (1st and Normal Edition): The first sentence of its Pokémon Power reads "Once during you turn" instead of "Once during your turn".
- Delibird (1st and Normal Edition): The energy cost for Delibird's attack is off the center.

- Gligar: The energy symbols on Gligar are not in the correct position. Also, in the description beneath the picture the Pokemon Type is missing the "n" from Flyscorpion. This applies to both 1st and Normal Editions.
- Shining Tyranitar: The word "just" is spelled wrong. It is written as "hust".
Legendary Collection Series
- Reverse Holofoil Exeggcute: Normally on Reverse Holofoils, the Energy costs for attacks aren't reflective. On Exeggcute, they are.
- Holofoil Dark Raichu: Electricity on the tail is holofoil, which is inconsistent with the original Team Rocket illustration. This misprint causes the tail of Dark Raichu to look disembodied.

- Dugtrio: Its Attack Energy Costs Symbols are larger than the standard size.
- Gengar: Gengar's Chaos Move Pokémon Power game text has a few spots where the text could go up a line.

- Totodile: When Cyndaquil's card is scanned with the e-Reader a "Cynda!" sound is added to the Melody Box. Totodile being scanned, however, adds "Wani!" rather than "Toto!". As Chikorita and Pikachu (two other cards which received this effect) have the same English and Japanese names, it is unknown if Totodile's was the error, or if Cyndaquil's is.
- Energy Removal 2 and Multi Technical Machine 01: When these cards are scanned with the e-Reader, the TM01 card names the card's move as "Paralyzing Stare" (on the card, it is "Paralyzing Gaze"), and the reader refers to "Energy Removal 2" as the ordinary "Energy Removal".
- Darkness Energy: The card text implies that it can add to damage done to benched Pokémon, which normally cannot be increased.

- Magnemite: The text on this card is quite faded as opposed to other Metal Pokémon in the set.
- Weakness Guard: The "Attach this card..." text is in its own separate paragraph, unlike other cards in the past.
- Ariados: In its Spider Force attack, it should say "Defending Pokémon", not "defending Pokémon". This error is not present in the non-holofoil version.
- Rare Holofoil Cards: For some reason, the bottommost cut out on the left side of the card is not holofoil.
- Nidoqueen: The period is misplaced at the left of the end of Nidoqueen's last attack. This applies to the Holofoil, Rare and Reverse Holofoil versions of the card.
- Persian: Under the "Surprise Slash" attack, it reads "You opponent". It should read "Your opponent".
- Nidoran♀: Nidoran♂ and Nidoran♀ were misspelled as "Nidoran ♂" and "Nidoran ♀", respectively.
- Slakoth: For some reason, the last "f" in the attack "Slack Off" isn't bolded.

- Vigoroth: there is a grammatical error under its "Focus Energy" attack where it says "Vigoroth's Slash is attack".
- Marill: This card is supposed to have a Retreat Cost of 1 but a third to a half of these cards were printed with a Retreat Cost of 0. Alternate Holofoil versions of this card don't have this error.
- Combusken: The card was printed as Stage 2 while it is supposed to be Stage 1. Only cards that were printed from EX Battle Stadium set have this error.

- Team Magma's Baltoy: Under the "Psymist" attack, it reads "choose 1 of you opponent's". It should read "choose 1 of your opponent's".
- Team Magma Belt: The "T" in Pokémon Tool isn't capitalized.

- Lanturn: Under the "Water Gun" attack, it reads "You can't add more then 40 damage in this way." It should read "more than".

POP Series 5
- Prerelease Raichu: Arguably the rarest card printed by Wizards. Rumored to have been about 6 to 50 made, some of which were retrieved by Wizards themselves. These cards came about during the printing of prerelease Clefable from Jungle, when some Base Set Raichu cards were attached to the side of sheets of Clefable cards. Wizards staff denied their existence for years, but have since confessed to the card's existence.

- Mewtwo: Promotional Mewtwo #3 was accidentally printed with the Pokémon the First Movie logo upside down in the lower left corner. So far only three have been found in this condition.
