Vaporeon is Pokédex #134, generation 1 (Kanto). Vaporeon is a Stage 1 Water Pokémon with 80 HP. The card lists level 42. The card says it evolves from Eevee. In this catalog that name is Eevee (#133).
Vaporeon sits at 12/64 in Jungle, position 12 of 64. Before it is 11 Snorlax, and after it is 13 Venomoth. The set belongs to the Base series. It was released on June 16, 1999. The printed size is 64, and the checklist is the same length. The listed rarity is Rare Holo.
The attack Quick Attack lists 10+ damage. The cost is Colorless, Colorless. Flip a coin. If heads, this attack does 10 damage plus 20 more damage; if tails, this attack does 10 damage. Water Gun is another attack lists 30+ damage. The cost is Water, Water, Colorless. Does 30 damage plus 10 more damage for each Water Energy attached to Vaporeon but not used to pay for this attack's Energy cost. Extra Water Energy after the 2nd doesn't count. Weakness is Lightning ×2. Retreat cost is 1. The flavor text reads "Lives close to water. Its long tail is ridged with a fin that is often mistaken for a mermaid's."
Vaporeon (#134) has 36 other cards in the catalog. Those other cards are in 28 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Vaporeon 28/64 in Jungle (1999). Both list 80 HP. The rarity there is Rare, and here it is Rare Holo. 34 other cards of Vaporeon list a different HP.
The illustrator line reads Kagemaru Himeno. I count 656 other cards in the catalog with that illustrator.
Jungle set binder is where a full Jungle set goes. This card fills one slot there. A generation binder holds one card of each species. Vaporeon can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Eevee and the Eeveelutions. I still need this card.
