Omastar is Pokédex #139, generation 1 (Kanto). Omastar is a Stage 2 Water Pokémon with 70 HP. The card lists level 32. The card says it evolves from Omanyte. In this catalog that name is Omanyte (#138).
Omastar sits at 40/62 in Fossil, position 40 of 62. Before it is 39 Magmar, and after it is 41 Sandslash. The set belongs to the Base series. It was released on October 10, 1999. The printed size is 62, and the checklist is the same length. The listed rarity is Uncommon.
The attack Water Gun lists 20+ damage. The cost is Water, Colorless. Does 20 damage plus 10 more damage for each Water Energy attached to Omastar but not used to pay for this attack's Energy cost. You can't add more than 20 damage in this way. Spike Cannon is another attack lists 30× damage. The cost is Water, Water. Flip 2 coins. This attack does 30 damage times the number of heads. Weakness is Grass ×2. Retreat cost is 1. The flavor text reads "A prehistoric Pokémon that died out when its heavy shell made it impossible for it to catch prey."
Omastar (#139) has 16 other cards in the catalog. Those other cards are in 14 sets. The other printings with a release date run from 2001 to 2023. The earliest other card is Omastar 43/75 in Neo Discovery (2001). That card lists 80 HP, and this one lists 70 HP. Both list the rarity Uncommon. Shin-ichi Yoshida illustrated that card, and Ken Sugimori illustrated this one. Retreat cost there is 2, and here it is 1. 14 other cards of Omastar list a different HP.
The illustrator line reads Ken Sugimori. I count 1,112 other cards in the catalog with that illustrator.
Fossil set binder is where a full Fossil set goes. This card fills one slot there. A generation binder holds one card of each species. Omastar can fill a slot in Generation 1 binder (Kanto). I still need this card.
