Gym Challenge is a set in the Gym series. It was released on October 16, 2000. The printed size is 132, and the checklist is the same length. Giovanni's Pinsir is 24/132, in position 24 of 132 on this checklist. Before it is 23 Giovanni's Nidoqueen, and after it is 25 Koga's Arbok. The listed rarity is Rare.
Giovanni's Pinsir is a Basic Grass Pokémon with 70 HP. The card lists level 27. In the Pokédex this is Pinsir (#127), generation 1 (Kanto).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Pinsir (#127) has 23 other cards in the catalog. Those other cards are in 21 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Pinsir 9/64 in Jungle (1999). That card is named Pinsir, while this one is Giovanni's Pinsir. That card lists 60 HP, and this one lists 70 HP. The rarity there is Rare Holo, and here it is Rare. Kagemaru Himeno illustrated that card, and Ken Sugimori illustrated this one. Retreat cost there is 1, and here it is 2. 20 other cards of Pinsir list a different HP.
The attack Snapping Pincers lists 10+ damage. The cost is Grass, Colorless. Flip a coin. If heads, this attack does 10 damage plus 10 more damage; if tails, this attack does 10 damage. Overhead Toss is another attack lists 40 damage. The cost is Grass, Colorless, Colorless. If you have any Benched Pokémon, flip a coin. If tails, choose 1 of your Benched Pokémon. This attack does 20 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Fire ×2. Retreat cost is 2.
I keep a set binder for Gym Challenge, meant to hold every card of that set. This card is one slot in the Gym Challenge set binder. A generation binder holds one card of each species. Pinsir can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Kanto Gym Leaders and their Pokémon, and Giovanni and his Pokémon. I still need this card.
