Base is a set in the Base series. It was released on 9 January 1999. The printed size is 102, and the checklist is the same length. Metapod is 54/102, in position 54 of 102 on this checklist. Before it is 53 Magnemite, and after it is 55 Nidoran ♂. The listed rarity is Common.
Metapod is a Stage 1 Grass Pokémon with 70 HP. The card lists level 21. In the Pokédex this is Metapod (#011), generation 1 (Kanto). The card says it evolves from Caterpie. In this catalog that name is Caterpie (#010). The card lists Butterfree, Butterfree (#012) under evolves to.
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Metapod (#011) has 18 other cards in the catalog. Those other cards are in 18 sets. The other printings with a release date run from 2000 to 2025. The earliest other card is Metapod 81/130 in Base Set 2 (2000). Both list 70 HP. Both list the rarity Common. 10 other cards of Metapod list a different HP.
The attack Stiffen lists no damage number. The cost is Colorless, Colorless. Flip a coin. If heads, prevent all damage done to Metapod during your opponent's next turn. (Any other effects of attacks still happen.) Stun Spore is another attack lists 20 damage. The cost is Grass, Grass. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. Weakness is Fire ×2. Retreat cost is 2. The flavor text reads "It is vulnerable to attack because its shell is soft, exposing its weak and tender body."
I keep a set binder for Base, meant to hold every card of that set. This card is one slot in the Base set binder. A generation binder holds one card of each species. Metapod can fill a slot in Generation 1 binder (Kanto). I still need this card.
