Gyarados (#130) has 56 other cards in the catalog. Those other cards are in 38 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 lists 100 HP, and this one lists 150 HP. Both list the rarity Rare Holo. Mitsuhiro Arita illustrated that card, and Hasuno illustrated this one. Retreat cost there is 3, and here it is 4. 55 other cards of Gyarados list a different HP.
The illustrator line reads Hasuno. I count 74 other cards in the catalog with that illustrator.
Team Up set binder is where a full Team Up 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 Magikarp and Gyarados. I still need this card.
