Gym Challenge is a set in the Gym series. It was released on 16 October 2000. The printed size is 132, and the checklist is the same length. Brock's Primeape is 35/132, in position 35 of 132 on this checklist. Before it is 34 Brock's Graveler, and after it is 36 Brock's Sandslash. The listed rarity is Uncommon.
Brock's Primeape is a Stage 1 Fighting Pokémon with 70 HP. The card lists level 32. In the Pokédex this is Primeape (#057), generation 1 (Kanto). The card says it evolves from Brock's Mankey. In this catalog that name is Mankey (#056).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Primeape (#057) has 24 other cards in the catalog. Those other cards are in 23 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Primeape 43/64 in Jungle (1999). That card is named Primeape, while this one is Brock's Primeape. Both list 70 HP. Both list the rarity Uncommon. Kagemaru Himeno illustrated that card, and Ken Sugimori illustrated this one. 20 other cards of Primeape list a different HP.
Scram is listed as Pokémon Power. If Brock's Primeape ever has exactly 10 HP left, shuffle it and all cards attached to it into your deck. This power stops working while Brock's Primeape is Asleep, Confused, or Paralyzed. The attack Mega Thrash lists 60 damage. The cost is Fighting, Fighting, Fighting. Brock's Primeape does 20 damage to itself. If there is a Stadium card in play, discard it. Weakness is Psychic ×2. Retreat cost is 1.
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. Primeape 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 Brock and his Pokémon. I still need this card.
