Base Set 2 is a set in the Base series. It was released on February 24, 2000. The printed size is 130, and the checklist is the same length. Poliwrath is 15/130, in position 15 of 130 on this checklist. Before it is 14 Pidgeot, and after it is 16 Raichu. The listed rarity is Rare Holo.
Poliwrath is a Stage 2 Water Pokémon with 90 HP. The card lists level 48. In the Pokédex this is Poliwrath (#062), generation 1 (Kanto). The card says it evolves from Poliwhirl. In this catalog that name is Poliwhirl (#061).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Poliwrath (#062) has 19 other cards in the catalog. Those other cards are in 16 sets. The other printings with a release date run from 1999 to 2024. The earliest other card is Poliwrath 13/102 in Base (1999). Both list 90 HP. Both list the rarity Rare Holo. 15 other cards of Poliwrath list a different HP.
The attack Water Gun lists 30+ damage. The cost is Water, Water, Colorless. Does 30 damage plus 10 more damage for each Water Energy attached to Poliwrath but not used to pay for this attack's Energy cost. You can't add more than 20 damage in this way. Whirlpool is another attack lists 40 damage. The cost is Water, Water, Colorless, Colorless. If the Defending Pokémon has any Energy cards attached to it, choose 1 of them and discard it. Weakness is Grass ×2. Retreat cost is 3. The flavor text reads "An adept swimmer at both the front crawl and breaststroke. Easily overtakes the best human swimmers."
I keep a set binder for Base Set 2, meant to hold every card of that set. This card is one slot in the Base Set 2 set binder. A generation binder holds one card of each species. Poliwrath can fill a slot in Generation 1 binder (Kanto). I still need this card.
