Fossil is a set in the Base series. It was released on 10 October 1999. The printed size is 62, and the checklist is the same length. Slowbro is 43/62, in position 43 of 62 on this checklist. Before it is 42 Seadra, and after it is 44 Tentacruel. The listed rarity is Uncommon.
Slowbro is a Stage 1 Psychic Pokémon with 60 HP. The card lists level 26. In the Pokédex this is Slowbro (#080), generation 1 (Kanto). The card says it evolves from Slowpoke. In this catalog that name is Slowpoke (#079).
Kagemaru Himeno illustrated this card. The same name is on 656 other cards in the catalog.
Slowbro (#080) has 26 other cards in the catalog. Those other cards are in 22 sets. The other printings with a release date run from 2000 to 2026. The earliest other card is Dark Slowbro 12/82 in Team Rocket (2000). That card is named Dark Slowbro, while this one is Slowbro. Both list 60 HP. The rarity there is Rare Holo, and here it is Uncommon. Mitsuhiro Arita illustrated that card, and Kagemaru Himeno illustrated this one. Retreat cost there is 2, and here it is 1. 22 other cards of Slowbro list a different HP.
Strange Behavior is listed as Pokémon Power. As often as you like during your turn (before your attack), you may move 1 damage counter from 1 of your Pokémon to Slowbro as long as you don't Knock Out Slowbro. This power can't be used if Slowbro is Asleep, Confused, or Paralyzed. The attack Psyshock lists 20 damage. The cost is Psychic, Psychic. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. Weakness is Psychic ×2. Retreat cost is 1. The flavor text reads "The Shellder that is latched onto Slowpoke's tail is said to feed on the host's left-over scraps."
I keep a set binder for Fossil, meant to hold every card of that set. This card is one slot in the Fossil set binder. A generation binder holds one card of each species. Slowbro can fill a slot in Generation 1 binder (Kanto). I still need this card.
