Gyarados is Pokédex #130, generation 1 (Kanto). Dark Gyarados is a Stage 1 Water Pokémon with 70 HP. The card lists level 31. The card says it evolves from Magikarp. In this catalog that name is Magikarp (#129).
Dark Gyarados sits at 8/82 in Team Rocket, position 8 of 83. Before it is 7 Dark Golbat, and after it is 9 Dark Hypno. The set belongs to the Base series. It was released on 24 April 2000. The printed size is 82. This checklist is longer, at 83 cards. The listed rarity is Rare Holo.
Final Beam is listed as Pokémon Power. When Dark Gyarados is Knocked Out by an attack, flip a coin. If heads, this power does 20 damage for each Water Energy attached to Dark Gyarados to the Pokémon that Knocked Out Dark Gyarados. Apply Weakness and Resistance. This power doesn't work if Dark Gyarados is Asleep, Confused, or Paralyzed. The attack Ice Beam lists 30 damage. The cost is Water, Water, Water. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. Weakness is Grass ×2. Resistance is Fighting -30. Retreat cost is 2. The flavor text reads "Normally found only in the deep ocean, it has recently been seen in shallow waters as well."
Gyarados (#130) has 56 other cards in the catalog. Those other cards are in 39 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Gyarados 6/102 in Base (1999). That card is named Gyarados, while this one is Dark Gyarados. That card lists 100 HP, and this one lists 70 HP. Both list the rarity Rare Holo. Mitsuhiro Arita illustrated that card, and Kagemaru Himeno illustrated this one. Retreat cost there is 3, and here it is 2. 54 other cards of Gyarados list a different HP.
The illustrator line reads Kagemaru Himeno. I count 656 other cards in the catalog with that illustrator.
Team Rocket set binder is where a full Team Rocket set goes. This card fills one slot there. A generation binder holds one card of each species. Gyarados can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Team Rocket cards and Magikarp and Gyarados. I still need this card.
